automatically assigns disks to RAID groups and creates new RAID groups as each RAID group is filled with its maximum number of disks. RAID group size: The following characteristics apply to RAID group size: The default number of disks in a RAID group (including the parity disk) is 14. A RAID group must contain at least two disks. The largest RAID group size you can create manually is 28 disks. The maximum RAID group size is 52 disks.
8VH 'LVN 6FUXEELQJ WR 3URWHFW 'DWD )URP 0HGLD (UURUV The filer uses the RAID disk scrubbing procedure to increase data availability. The filer scans each disk in the RAID group for media errors.

(IIHFWV RI 'LVN )DLOXUH RQ )LOHU 2SHUDWLRQ The effects of a disk failure on filer operation depend on whether the filer has a hot spare disk. Without a hot spare disk: If the filer is not equipped with a hot spare disk, after a disk fails the filer enters a state called degraded mode.
The sysconfig -r command displays which disk is reserved as the hot spare disk. In addition to disk failure and hot spare disk replacement activity, the /etc/messages file logs any failure in a periodic check of the hot spare disk. Command to control RAID data reconstruction speed: You can control the speed of RAID data reconstruction by entering the following command: RSWLRQV UDLG UHFRQVWUXFWBVSHHG VSHHG where speed is a number ranging from 1 (slowest) to 10 (fastest).
The filer uses two naming conventions to indicate the root volume: /vol/vol0 / In the /vol/vol0 convention /vol Indicates that the next part of the path, such as vol0 in this example, is a volume name. /vol0 Indicates the default name of the root volume for a filer. You can change this name using the vol rename command. Mounting volumes: On filers configured with multiple volumes, mounting / is equivalent to mounting /vol/vol0/, (where vol0 is the root directory of the root volume).
Take individual volumes off-line, for example, to perform administrative tasks on their file systems or associated RAID groups, while the other volumes remain online, without interrupting the availability of the data on them. Limitations of configuring with multiple volumes include The filers storage space is partitioned. You can expand but not concatenate, shrink, or split volumes.

Because these clients interact with a file server differently, you need to understand how the read and write operations performed by one client affect the operations performed by the other client.
Byte-range locks work on portions of a file. Byte-range operations other than reads by a UNIX-based NFS client fail if the attempted operation is forbidden by the lock. As is appropriate for NFS, a UNIX-based NFS application might be forbidden to access a byte-range that is locked by CIFS. NOTE: There is one exception to the enforcement of locks set by CIFS clients on the filer.
CIFS client applications often perform operations such as writing to a temporary file, renaming the original file to a backup name, then renaming the temporary file to the original name. Therefore, take care in using symbolic links whose ultimate target is a file, as opposed to a directory.
+RZ WR 3UHYHQW 6\PEROLF /LQN &\FOLQJ You can create directory structures that are cyclic by creating a symbolic link that refers to a directory higher in the same tree, through use of a symbolic link having a dot or dot-dot component. Therefore, a simple recursive descent of the tree goes deeper and deeper until the maximum path length is reached. At that point an error is returned.
described in the preceding paragraph, a file with the read-only bit turned on appears to an NFS client not to have any write permission bits turned on. If a file has no write permission bits turned on and an NFS client turns on any write permission bit, the filer turns off the read-only bit for that file.

It truncates the file name to six characters. 2. It appends a tilde (~) and a number or letter to the name.
&DVH 6HQVLWLYLW\ LQ )LOH 1DPHV Uppercase and lowercase characters are significant to NFS clients but not to CIFS clients. For example, if a file named specifications already exists, an NFS user can still save another file under the name Specifications, but a CIFS user is instructed by the application to choose another file name. This section describes how both NFS and CIFS users can use file names that differ only by case. When a client creates a file name, the filer preserves the case.

6QDSVKRWV 0DLQWDLQ 2ULJLQDO )LOH 3HUPLVVLRQV Snapshot files carry the same permissions and inode numbers as the original files, keeping the integrity of the security system intact. Inodes are data structures that hold information about files on the filer. There is an inode for each file and a file is uniquely identified by the file system on which it resides and its inode number on that system.
Before any snapshot is taken, disk space is consumed by the active file system only. After a snapshot is taken, the active file system and snapshot point to the same disk blocks. The snapshot doesn´t use extra disk space. After the foo file is deleted, the space previously used by foo is referenced by the snapshot. That´s why deleting active file system data doesn´t free disk space.
6QDSVKRW &RPPDQGV DQG 2SWLRQV 6QDSVKRW &RPPDQGV The commands related to snapshots are listed in Table 9-1. If the volume name is omitted in any of these commands, the command applies to the root volume. 7DEOH 6QDSVKRW &RPPDQGV &RPPDQG 0HDQLQJ snap lista volume_name Lists all available snapshots. snap create volume_name snapshot_name Creates a snapshot with a specified name. snap delete volume_name snapshot_name Deletes a specified snapshot. snap rename volume_name from to Renames a snapshot.
$XWRPDWLF 6QDSVKRW &UHDWLRQ The filer uses the snap sched command to create snapshots automatically and to keep them on-line for a predetermined amount of time. 7\SHV RI $XWRPDWLF 6QDSVKRWV Table 9-3 describes the three types of automatic snapshots. 7DEOH $XWRPDWLF 6QDSVKRW 7\SHV 7\SH 'HVFULSWLRQ Weekly The filer creates these every Sunday at midnight. Weekly snapshots are called weekly.n, where n is an integer. weekly.0 is the most recent weekly snapshot, and weekly.

Create a snapshot every day and keep a maximum of six. Create a snapshot every hour, or at the times listed in the optional time list and keep a maximum of eight. Optional list of times, in 24-hour format at which an hourly snapshot is created.
The following list shows the snapshots that are created by this snapshot schedule in 1998 (when January 11 is a Sunday): % ls -lu .
([DPSOH For example, if you want to create two snapshots for the volume named vol1 each week, you can set up a cron job on the administration host to run twice each week at an appropriate time to execute the following snap create command: rsh filer snap create vol1 filename NOTE: The snap create command does not accept a snapshot name containing a slash (/).
NOTE: The numbers in this example were rounded off to make the example easier to understand. Also, to make the output easier to read, the Mounted on column is not included in the sample df output in the following sections. In this example, the vol0 volume contains 4 GB of disk space. It has 1 GB (or 25%) reserved for snapshots (the idea of reserving space for snapshots is described in more detail later). That leaves 3 GB for the active file system, and 2 GB of the file system is in use.
$GPLQLVWHULQJ 6QDSVKRW 'LVN 6SDFH Even with the snapshot reserve, the job of administering snapshot disk space consumption is important. There is no way to prevent snapshots from consuming disk space greater than the amount reserved for them. Consider what would happen in the example if all files in the active file system were deleted. Before the deletion, the df output was as follows: Filesystem /vol/vol0/ /vol/vol0/.
(IIHFWV RI 6QDSVKRWV RQ 4XRWDV Quotas do not count disk space consumed by snapshots. If snapshots were included in the quota calculations, users could end up in a state where they could not create any new files until all snapshots containing their old files expired.
If the data changes very quickly, reduce the number of snapshots scheduled. For example, if a volume is filled and emptied each day, for example, a volume storing large temporary files for a CAD application, it might not make sense to use daily or weekly snapshots at all. On a very active volume, schedule snapshots every hour and keep them for just a few hours, or turn off snapshots.
The first number is equal to cumulative snapshot space x 100% cumulative snapshot space + file system space The second number is equal to this snapshot x 100% this snapshot + file system space 7KH 7RWDO &ROXPQ The %/total column shows space consumed as a percentage of total disk space in the volume.
If you do not want the total amount of disk space consumed by all snapshots to exceed a certain percentage of the used disk space, use the cumulative values in the snap list output to determine which snapshots to delete. In the preceding example, if you dont want more than 5% of used disk space to be spent by snapshots, delete all snapshots listed below nightly.1 in the snap list output; that is, nightly.2, nightly.3, and nightly.4. After deleting the snapshots, nightly.

$FFHVVLQJ 6QDSVKRWV )URP &OLHQWV $ERXW &OLHQW $FFHVV WR 6QDSVKRWV Snapshots can be accessed by any user with the appropriate permissions. Every directory in the filers active file system contains a directory named .snapshot, through which users can access old versions of files in that directory. How users gain access to snapshots depends on the file-sharing protocol used: NFS or CIFS.
For example, at the mount point of a filer file system, a directory listing looks like this: ls -a . .. .snapshot dir1 dir2 The same command entered in a directory below the mount point does not show the .snapshot directory; for example: cd dir1 ls -a . .. file1 file2 If you enter the ls command with the directory name .snapshot, you can see a listing of the snapshots for the dir1 directory: ls .snapshot hourly.0 hourly.1 hourly.2 hourly.3 hourly.4 hourly.5 hourly.6 hourly.7 nightly.0 nightly.

There is no limit as to how much disk space or how many files the user mfisher can use. You can, however, use the quota report command to display the amount of disk space and the number of files used by this user. Both user and group quotas apply to the entire specified volume (or the root volume if no volume name is specified). This is true even if the quota target in the quotas file is specified in the form of a path name.
5HVL]LQJ 4XRWDV The quota resize command updates active quotas without recalculating disk usage, and is faster than quota off followed by quota on. An active quota is one that appears in the output of the quota report command, discussed in Displaying Information about Quotas. You use the quota resize command after changing limits for a group or user. For example, jdoe has a disk quota of 500 MB, as shown in the following example.
Because the quota target now has an active quota record, you can enter the quota resize command, including the volume name, to make the quota entry go into effect. This procedure takes less time than executing the quota off command followed by the quota on command because only the newly active quota is recalculated.
Alternatively, if jdoe is already under quota restriction, for example, if his files were restricted by a default user quota, enter the following command so that the user quota you just created can take effect: TXRWD UHVL]H KRPH &UHDWLQJ D *URXS 4XRWD Follow these steps to limit disk space used by a group named service: 1.

disk NAME disk - RAID disk configuration control commands SYNOPSIS disk fail disk_name disk remove disk_name disk scrub start disk scrub stop disk swap disk unswap DESCRIPTION The disk fail command forces a file system disk to fail; the disk remove command unloads a spare disk so that you can physically remove the disk from the filer. The disk scrub command causes the filer to scan disks for media errors.
disk disk being removed is available, the contents of the disk being removed will be reconstructed onto that spare disk. The disk being removed is marked as broken, so that if it remains in the disk shelf, it will not be used by the filer as a spare disk, and if it is moved to another filer, it will not be used by that filer as a spare disk. disk remove disk_name removes the specified spare disk from the RAID configuration, spinning the disk down when removal is complete.
disk_fw_update NAME disk_fw_update - update disk firmware SYNOPSIS disk_fw_update [ disk_name ] DESCRIPTION Use the disk_fw_update command to update out-of-date firmware on all disks or a specified disk on a filer. Each filer is shipped with a /etc/disk_fw directory that contains the latest firmware revisions. This command makes disks inaccessible for up to 2 minutes, so network sessions using the filer should be closed down before running it.
download NAME download - install new version of Data ONTAP 5.3 SYNOPSIS download DESCRIPTION download copies Data ONTAP 5.3 executable files from the /etc/boot directory to the filers boot block on the disks from which the filer boots. To install a new version of Data ONTAP 5.3, extract the files for the new release onto the filer from either a CIFS or an NFS client that has write access to the filers root directory.
dump NAME dump - file system backup SYNOPSIS dump [ options [ arguments ] ] subtree DESCRIPTION The dump command examines files in a subtree and writes to tape the files that need to be backed up. The Data ONTAP 5.3 dump command differs slightly from the standard UNIX dump, but the output format is compatible with SunOS 4.x/ Solaris 1.x and SunOS 5.x/Solaris 2.x dump. Data ONTAP 5.
dump Another advantage of running the dump command through rsh is that you can control backups from UNIX shell scripts or crontab entries. OPTIONS 0-9 Dump levels. A level 0, full backup, guarantees the entire file system is copied. A level number above 0, incremental backup, tells dump to copy all files new or modified since the last dump of a lower level. The default level is 0. f files Write the backup to the specified files.
dump /etc/dumpdates may be edited to change any of the fields, if necessary. See dumpdates for details. b factor Set the tape blocking factor in k-bytes. The default is 63 KB. If the density is set to greater than 6250 BPI, then the default blocking factor is 32 KB. NOTE: Some systems support blocking factors greater than 63 KB by breaking requests into 63-KB chunks or smaller using variable sized records; other systems do not support blocking factors greater than 63 KB at all.
dump To make a level 0 dump of /home on a 2 GB tape to a remote tape device, use: filer> dump 0ufbB adminhost:/dev/rst0 63 2097151 /home To make a level 0 dump of /home on a 2 GB tape to a local tape drive (no rewind device, unit zero, highest density) use: filer> dump 0ufbB nrst0a 63 2097151 /home To make a level 0 dump of the entire file system to a local tape drive (no rewind device, unit zero, highest density), with each tape file in the dump being less than 2 GB in size, without operator intervention,
dump performed on the filer. It can also be performed via a restore done on an NFS client machine; if such a restore is being done, the client system should be checked to ensure it supports SunOS-compatible dump/restore format. Client Dump and Restore Capability If a client is to be used for performing filer dump and/or restore, it is important to check what the maximum dump and restore capabilities of your client system are before setting up a dump schedule.
dump load another tape and use the norewind tape device to dump etc, finance, home and users subtrees to that tape volume. CIFS Data The Data ONTAP 5.3 dump command dumps the CIFS attributes and 8.3 name data for each file that is backed up. This data will not be backed up by a dump run on an NFS client machine. This data will not be restored by a restore run on an NFS client machine. This data will only be restored if a local restore is done of a backup created by the Data ONTAP 5.3 dump command.
exportfs NAME exportfs - export and unexport files or directories SYNOPSIS exportfs [ -aiuv ] [ -o options ] [ pathname ] DESCRIPTION If no pathname is specified, exportfs lists all currently exported directories and files. If pathname is specified, exportfs makes the specified file or directory available or unavailable for mounting by NFS clients. OPTIONS -a Takes the list of path names to be exported or unexported from the /etc/ exports file.
exportfs root=hostname[:hostname]... Give root access only to the specified hosts. By default, no hosts are granted root access. Netgroup names are not allowed in the list. When you export a file or directory using the ro, rw, or root option, you can specify that the file or directory be exported to a subnet instead of individual hosts. You cannot export to a subnet when using the access option.
fctest NAME fctest - test Fibre Channel environment SYNOPSIS fctest [ adapter ] DESCRIPTION Use the fctest command to test Fibre Channel adapters and disks on an appliance. This command provides a report of the integrity of your Fibre Channel environment. It is only available in maintenance mode, and takes about 5 minutes to complete. If the adapter argument is missing, all Fibre Channel adapters and disks in the system are tested, otherwise only the specified adapter, and disks attached to it, are tested.
fctest Crc = number of CRC errors observed in the Fibre Channel frames. Sync = number of Fibre Channel synchronization errors. F = the total number of inbound and outbound frames seen by the adapter.
filestats NAME filestats - collect file usage statistics SYNOPSIS filestats [ ages ages] [ timetype {a,m,c,cr}] [ sizes sizes] [ snapshot snapshot_name] [ style style] [ volume volume_name] DESCRIPTION The filestats utility provides a summary of file usage within a volume. It must be used on a snapshot, and the only required argument is the snapshot name. The volume name defaults to vol0 if not specified. If the volume you are examining is named otherwise, specify the name explicitly.
filestats atime Time of last read or write (in seconds). mtime Time of last write (in seconds). ctime Time of last size/status change (in seconds). crtime Time file was created (in seconds). atimeage Age of last read or write (Now - atime). mtimeage Age of last write (Now - mtime). ctimeage Age of last size/status change (Now ctime). crtimeage Age of file creation (Now - crtime). timetype timetype This lets you specify the type of time that will be used in the age comparison.
filestats 3. Produce file usage breakdowns for inodes whose size is less than 100000 bytes and whose access time is less than a day old: filestats volume vol0 snapshot hourly.1 expr {size}<100000&&{atimeage}<86400) 4. Produce a breakdown of the total number of files and their total size. You can control the set of ages and sizes that get used for this breakdown, with the ages and sizes arguments. The output also contains a breakdown of file usage by user-id and group-id. filestats snapshot hourly.
halt NAME halt - stop the filer SYNOPSIS halt [ -d ] [ -t mins ] DESCRIPTION halt flushes all cached data to disk and drops into the monitor. NFS clients can maintain use of a file over a halt or reboot (although experiencing a failure to respond during that time), but CIFS clients cannot do so safely. Therefore, if the filer is running CIFS, the halt command invokes cifs terminate, which requires the -t option.
help NAME help - print summary of commands and help strings SYNOPSIS help [ command ... ] ? [ command ... ] DESCRIPTION help prints a summary for each command in its argument list. With no arguments, help prints a list of all available Data ONTAP 5.3 commands. Full UNIX-style man pages for all filer commands and files are available in the /etc/man directory.
hostname NAME hostname - set or display Dell filer name SYNOPSIS hostname [ name ] DESCRIPTION hostname prints the name of the current host. The hostname can be set by supplying an argument. This is usually done in the initialization script, /etc/rc, which is run at boot time. name must exist in the /etc/hosts data base.
httpstat NAME httpstat - display HTTP statistics SYNOPSIS httpstat [ -tz ] [ interval ] DESCRIPTION httpstat displays statistical information about HTTP (HyperText Transfer Protocol) for the filer. It can also be used to reinitialize this information. If no arguments are given, httpstat displays statistical information since last reboot, or last zeroed with the -z option. If the -t option is specified, statistical information since the last reboot is given.
ifconfig NAME ifconfig - configure network interface parameters SYNOPSIS ifconfig interface [ [ alias | -alias ] address ] [ netmask mask ] [ broadcast address ] [ mediatype type ] [ mtusize size ] [ up | down ] [ trusted | untrusted ] [ wins | -wins ] ifconfig -a DESCRIPTION ifconfig assigns an address to a network interface and configures network interface parameters.
ifconfig duplex 10Base-T RJ-45 twistedpair), or 100tx (100Base-T RJ-45 twistedpair), or 100tx-fd (Full duplex 100Base-T RJ-45 twisted-pair), or auto (Auto RJ-45 twisted-pair). The default media type is set to tp or to auto where applicable. On a 10/100 Mbps auto-negotiable interface, the system will auto-negotiate a 10 Mbps half or full duplex or 100 Mbps half or full duplex link and set the network interface accordingly when it is configured up.
ifconfig untrusted Specifies that the network to which the network interface is attached is not trusted relative to firewall-style security. wins Specifies that the network interface is to be registered with Windows Internet Name Services (default). Such registration is only performed when CIFS is running and at least one WINS server has been configured. -wins Specifies that the network interface is not to be registered with Windows Internet Name Services.
ifstat NAME ifstat - display device-level statistics for network interfaces SYNOPSIS ifstat [ -z ] -a | interface_name DESCRIPTION The ifstat command displays statistics about packets received and sent on a specified network interface or on all network interfaces. The statistics are cumulative since the filer was booted. The -z argument clears the statistics. The -a argument displays statistics for all network interfaces including the virtual host and the loopback address.
license NAME license - license Data ONTAP 5.3 services SYNOPSIS license [ service=code ] ... DESCRIPTION The license command enables you to enter license codes for specific Data ONTAP 5.3 services. The license codes are provided by Dell. With no arguments, the license command prints the current list of licensed services and their codes. It also shows the services that are not licensed for your filer.
logout NAME logout - use control-D to logout DESCRIPTION The filer doesnt have a logout command. (Since the telnet connection and the console are multiplexed into the same session, there would be no way for a logout command to tell which connection to drop.) To log out, type control-D. Over telnet, typing control-D disconnects the session. On the console, typing control-D returns the console to the password prompt. If no password is set, control-D has no effect.
maxfiles NAME maxfiles - increase the number of files the volume can hold SYNOPSIS maxfiles [ vol_name [ max ] ] DESCRIPTION maxfiles increases the number of files that a volume can hold to max. Once increased, the value of max can never be lowered, so the new value must be larger than the current value. If no argument is specified, maxfiles displays the current value of max for all volumes in the system. If just the vol_name argument is given, the current value of max for the specified volume is displayed.
mt NAME mt - magnetic tape positioning and control SYNOPSIS mt [ -f | -t tapedevice ] command [ count ] [ command [ count ] ... ] DESCRIPTION mt is used to position or control the specified magnetic tape drive supporting the commands listed below. Commands that support a count field allow multiple operations to be performed (the rewind, status and offline commands do not support a count field). mt will output failure messages if the specified tape drive cannot be opened or if the operation fails.
mt EXAMPLES The following example uses mt to display status information for the no-rewind tape device, unit zero, highest format (density): filer> mt -f nrst0a status Tape drive: Exabyte 8505 8mm Status: ready, write enabled Format: EXB-8500C (w/compression) fileno = 0 blockno = 0 resid = 0 To skip over a previously created dump file to append a dump onto a no-rewind tape device, use the fsf (forward space file) command: filer> mt -f nrst0a fsf 1 SEE ALSO sysconfig, tape A-54 Dell PowerVault 720N, 740N, an
netstat NAME netstat - show network status SYNOPSIS netstat [ -an ] netstat -mnrs netstat -i | -I interface [ -dn ] netstat -w interval [ -i | -I interface ] [ -dn ] netstat [ -p protocol ] DESCRIPTION The netstat command symbolically displays the contents of various networkrelated data structures. There are a number of output formats, depending on the options for the information presented. The first form of the command displays a list of active sockets for each protocol.
netstat -n Show network addresses as numbers. netstat normally interprets addresses and attempts to display them symbolically. This option may be used with any of the display formats that display network addresses. -p protocol Show statistics about protocol , which is one of tcp, udp, ip, or icmp. A null response typically means that there are no interesting numbers to report. The program will complain if protocol is unknown or if there is no statistics routine for it. -s Show per-protocol statistics.
netstat H The route is to a host (otherwise, its to a net). L The route includes valid protocol to link address translation. M The route was modified dynamically by a redirect. R The route has timed out. S The route was manually added with a route command (see route). U The route is usable (up). Direct routes are created for each interface attached to the local host; the gateway field for such entries shows the address of the outgoing interface.
nfs NAME nfs - turn NFS service off and on SYNOPSIS nfs [ on | off ] DESCRIPTION nfs turns NFS service off or on. With no arguments, nfs shows the current state of NFS service. nfs is normally used in the initialization command script, /etc/rc.
nfsstat NAME nfsstat - display NFS statistics SYNOPSIS nfsstat [ interval ] nfsstat [ -c ] [ -t ] -h [ ip_address | host_name ] nfsstat -l [ -t ] nfsstat -z DESCRIPTION nfsstat displays statistical information about NFS (Network File System) and RPC (Remote Procedure Call) for the filer. It can also be used to reinitialize this information. If no arguments are given, nfsstat displays statistical information since last zeroed with the -z option (or since reboot if statistics have not been zeroed).
nfsstat DISPLAYS The server RPC display includes the following fields, with separate values for TCP and UDP: calls The total number of RPC calls received. badcalls The total number of calls rejected by the RPC layer (the sum of badlen and xdrcall as defined below). nullrecv The number of times an RPC call was not available when it was thought to be received. badlen The number of RPC calls with a length shorter than a minimumsized RPC call.
options NAME options - display or set filer options SYNOPSIS options [ option value ] ... DESCRIPTION options is used to change configurable filer software options. If no options are specified, then options prints the current value of all available options. The default value for most options is off, which means that the option is not set.
options the users lower-cased Windows login name, they will see a share of that name (truncated to 12 characters) that is their home directory. Only the user can access the home directory using this share. All other users cannot see the share name since they are logged in under a different user. cifs.idle_timeout Specifies the amount of idle time in seconds before the filer disconnects a session. An idle session is a session in which a user does not have any files opened on the filer.
options If you do not plan to use share-level ACLs to control access to UNIX security style files (e.g. in a UNIX qtree), you might wish to change this setting to on. cifs.save_case By default, the filer preserves the case of CIFS names, even though a case insensitive hash and search is done.
options symbolic links and will repeatedly loop on them. Users should use caution when changing this option. cifs.symlinks.enable When cifs.symlinks.enable is on (the default), if the object being accessed by a CIFS client is a symbolic link (whether absolute or relative), the filer follows the link with the proviso that the ultimate target turns out to reside within the originating share (thus ensuring that the client has access permission to the target). cifs.trace_login When cifs.
options name /etc/http/man/name can be accessed with the URL http:// filer/na_admin/man/name. httpd.log.max_file_size Specifies the maximum size that the HTTP log file /etc/log/ httpd.log can grow to. The default is 2147483647, which is the largest file size that many clients support. httpd.rootdir Specifies the complete pathname of the root directory that contains files and subdirectories for HTTP access. httpd.
options nfs.v3.enable When enabled, the NFS server supports NFS version 3. By default, the feature is enabled; it can be disabled if there is a problem with some client when using NFS version 3, and that client cannot be configured to use NFS version 2. nfs.webnfs.enable When enabled, the NFS server supports WebNFS lookups. By default, WebNFS lookups are disabled. nfs.webnfs.rootdir Specifies the WebNFS rootdir.
options telnet.enable Enables the Telnet server on the filer. telnet.hosts Specifies up to 5 clients that will be allowed telnet access to the server. The host names should be entered as a commaseparated list with no spaces in between. Enter a * to allow access to all clients; this is the default. Enter a - to disable telnet access to the server. timed.enable Determines whether a time daemon (timed) runs on the filer. If timed.enable is on, the filer synchronizes its time with a time server. timed.
options wafl.convert_ucode Setting this option to ON forces conversion of all directories to Unicode format when accessed from both NFS and CIFS. By default (OFF), access from CIFS causes conversion of pre-4.0 and 4.0 format directories; access from NFS causes conversion of 4.0 format directories. vol.copy.throttle Specifies the default speed of all volume copy operations. The speed can be a number in the range from 1 to 10, 10 being the highest speed and the default. wafl.
options wafl.wcc_minutes_valid Specifies the number of minutes a WAFL credential cache entry is valid. The value can range from 1 through 20160. The default is 20. Multiple options can be set at once in an options command. For example: options nfs.tcp.enable on nfs.v2.df_2gb_lim on raid.timeout 48 sets nfs.tcp.enable to on, sets nfs.v2.df_2gb_lim to on, and sets raid.timeout to 48.
passwd NAME passwd - modify the system administrative users password SYNOPSIS passwd DESCRIPTION passwd changes the filers administrative users password. First it prompts you for the login name (if any non-root users are configured). Then it prompts you for the current password. If you type the current password correctly, the filer requests a new password. The passwd command imposes no minimum length or special character requirements for root .
ping NAME ping - send ICMP ECHO_REQUEST packets to network hosts SYNOPSIS ping [ -s ] [ -Rrv ] host [ packetsize [ count ] ] DESCRIPTION ping uses the ICMP protocols mandatory ECHO_REQUEST datagram to elicit an ICMP ECHO_RESPONSE from the specified host or gateway. ECHO_REQUEST datagrams have an IP and ICMP header, followed by a struct timeval and then an arbitrary number of bytes used to fill out the packet. If host responds, ping prints host is alive.
qtree NAME qtree - create and manage qtrees SYNOPSIS qtree qtree create [ name ] qtree security [ name [ UNIX | ntfs | mixed ] ] qtree oplocks [ name [ enable | disable ] ] DESCRIPTION The qtree command creates qtrees and specifies attributes for qtrees. A qtree can be an entire volume or a subset of a volume. It is similar to a partition in that you cannot move files into or out of a qtree.
qtree To delete a qtree, remove it from a client as you would any directory. You can create up to 254 qtrees on a filer. The qtree security command changes the security style for files and directories. Security style means the method the filer uses to determine whether a user has access to a file. If name is the path name to a qtree, the security style applies to the files and directories in the specified qtree. The path name to a qtree does not need to end with a slash.
qtree If the cifs.oplocks.enable option is off, oplocks are not sent even if you enable the oplocks on a per-quota-tree basis with the qtree oplocks command. The cifs.oplocks.enable option is enabled by default. If you do not specify enable or disable in the qtree oplocks command, the oplock attribute for name is displayed. If you omit name, the oplock attributes for all quota trees on the filer are displayed.
quota NAME quota - control filer disk quotas SYNOPSIS quota [ on | off | resize ] [ volume ] quota report [ path ] quota qtree [ name ] DESCRIPTION A quota limits the amount of disk space and the number of files that a particular user or group can consume. A quota can also restrict the total space and files used in a qtree, or the usage of users and groups within a qtree. A request that would cause a user or group to exceed an applicable quota fails with a disk quota exceeded error.
quota an entry in /etc/quotas to increase a users quota, quota resize will cause the change to take effect. The volume name may be omitted if the system has only one volume. quota resize can be used only when quotas are already on. Because it does not rescan the file system to compute usage, quota resize is faster than turning quotas off and then on again. quota resize will apply all updated entries in /etc/quotas; however, it will generally ignore newly added entries.
rdate NAME rdate - set system date from a remote host SYNOPSIS rdate hostname DESCRIPTION rdate sends a request to the time server on hostname and sets the local date and time to the value returned by the server. rdate will time out if the server doesnt respond in 10 seconds. rdate can be added to /etc/rc to automatically synchronize the system time with the time server on each reboot.
reboot NAME reboot - stop and then restart the filer SYNOPSIS reboot [ -d ] [ -t minutes ] DESCRIPTION reboot halts the filer and then restarts it. reboot is commonly used to allow modified configuration files to take effect or to run a newly installed version of Data ONTAP 5.3. NFS clients can maintain use of a file over a halt or reboot (although experiencing a failure to respond during that time), but CIFS clients cannot do so safely.
restore NAME restore - restore files or file systems from backups made with the filers dump command SYNOPSIS restore key args... DESCRIPTION The restore restores files from backup tapes created with the dump (see dump) command. A full backup of a file system may be restored and subsequent incremental backups layered on top of it. The actions of restore are controlled by the given key, which is a string of characters containing at most one function letter and possibly one or more function modifiers.
restore b The next argument to restore is used as the block size of the media (in kilobytes). If the b option is not specified, restore tries to determine the media block size dynamically. f The next argument to restore is used as the name of the archive instead of the standard input. If the name of the file is -, restore reads from standard input. s The next argument to restore is a number which selects the file on a multifile dump tape. File numbering starts at 1.
restore Tape read error while restoring filename Tape read error while skipping over inode inumber Tape read error while trying to resynchronize A tape (or other media) read error has occurred. If a file name is specified, then its contents are probably partially wrong. If an inode is being skipped or the tape is trying to resynchronize, then no extracted files have been corrupted, though files may not be found on the tape.
route NAME route - manually manipulate the routing table SYNOPSIS route [ -fn ] add|delete [ host|net ] destination gateway [ metric ] DESCRIPTION route allows the system administrator to manually manipulate the network routing table for the specific host or network specified by destination. The gateway argument is the nexthop gateway to which packets should be addressed for the corresponding destination. The metric argument indicates the number of hops to the destination.
route DIAGNOSTICS add [ host|net] destination:gateway The specified route is being added to the table. delete [ host|net] destination:gateway The specified route is being deleted. destination gateway done When the -f flag is specified, each routing table entry deleted is indicated with a message of this form. network unreachable An attempt to add a route failed because the gateway listed was not on a directly-connected network. The next-hop gateway must be given.
routed NAME routed - network routing daemon SYNOPSIS routed on routed off routed [ -n ] status DESCRIPTION routed (pronounced route-D) uses a variant of the Xerox NS Routing Information Protocol (RIP) to manage selection of the default gateway used for IP network routing.
routed In addition, when routed is running, it deletes dynamic routes, created by ICMP redirects, every 3 minutes. USAGE routed on The route daemon may be turned on at any time with the routed on command. This causes routed to read the /etc/ dgateways file, and turn on RIP snooping, dynamic route timeouts, and default gateway selection. If routed is already running, this option causes it to reread the /etc/dgateways file, and reinitialize. By default, routed is invoked at boot time in /etc/rc.
routed FILES /etc/rc for default initialization /etc/dgateways for the list of default gateways. SEE ALSO netstat, route, setup, dgateways, rc DIAGNOSTICS routed: unable to allocate free entry - too many valid entries were found in the /etc/dgateways file. Only the first 128 are used. routed: duplicate gateway entry not allowed - a duplicate gateway name or address was found in the /etc/dgateways file. Only the first one found is used.
savecore NAME savecore - save a core dump SYNOPSIS savecore DESCRIPTION savecore is meant to be called near the end of the initialization file /etc/rc. Its function is to save the core dump of the system (assuming one was made) and to write the panic string to /etc/messages. savecore saves the core dump in two files /etc/crash/core.n, and /etc/crash/core.n-small, where n is determined by the /etc/crash/bounds file.
setup NAME setup - update filer configuration SYNOPSIS setup DESCRIPTION setup queries the user for the filer configuration parameters such as hostname, IP address, and timezone. It installs new versions of /etc/rc, /etc/hosts, /etc/ exports, /etc/resolv.conf, /etc/hosts.equiv, and /etc/dgateways to reflect the new configuration. When setup completes, the configuration files have been updated, but their new contents do not take effect until the filer is rebooted (see reboot).
setup SEE ALSO ifconfig, reboot, dgateways, exports, hosts, hosts.equiv, resolv.
shelfchk NAME shelfchk - verify the communication of environmental information between disk shelves and the filer SYNOPSIS shelfchk DESCRIPTION The shelfchk command verifies that the disk shelves and the filer can exchange environmental information. If the environmental information is being exchanged, you can hotswap disks in the disk shelves. The shelfchk command is interactive. It requires that you type in your responses after observing the LEDs on the disks.
shelfchk In the following example, the shelfchk command finds an error: filer> shelfchk Only shelves attached to ha 9a should have all LEDs ON. Are these LEDs all ON now? n *** Your system may not be configured properly. Check cable connections.
snap NAME snap - manage snapshots SYNOPSIS snap list [ vol_name ] snap create | delete vol_name name snap rename vol_name from to snap sched [ vol_name [ weeks [ days [ hours[@list] ] ] ] ] snap reserve [ vol_name [ percent ] ] DESCRIPTION The snap family of commands provides a means to create and manage snapshots in each volume. A snapshot is a read-only copy of the entire file system as of the time the snapshot was created.
snap using the sched command, then on the hour, hourly.7 would be deleted, hourly.0 would be renamed to hourly.1, and so on. USAGE snap list [ vol_name ] displays a single line of information for each snapshot. Along with the snapshots name, it shows when the snapshot was created and the size of the snapshot. If you include the vol_name argument, list displays snapshot information only for the specified volume. With no arguments, it displays snapshot information for all volumes in the system.
snmp NAME snmp - set and query SNMP agent variables SYNOPSIS snmp snmp authtrap [ 0 | 1 ] snmp community [ add | delete ro | rw ] snmp contact [ contact ] snmp init [ 1 ] snmp location [ location ] snmp traphost [ add | delete hostname | ipaddress ] snmp traps [ on | off | reset | delete ] snmp traps trapname[.parameter value | on | off | reset delete] DESCRIPTION The snmp command is used to set and query configuration variables for the SNMP agent daemon (see snmpd).
snmp community [ add|delete ro|rw community ] Add or delete communities with the specified access control type. Specify ro for a read-only community and rw for a read-write community. For example, to add the read-only community private use the following command: snmp community add ro private Currently the SNMP SetRequest PDU is not supported, so all readwrite communities will default to read-only. The default community for the filer SNMP agent is public and its access mode is ro.
snmp trapname[.parameter value | on | off | reset | delete] traps affects a specified trap. It assigns a parameter and value, or turns it on or off, or resets or deletes it. You can trap on any MIB variable, but to do so you need a trap data parser function at the traphost application or a management script to interpret the TRAP name, OID value fields, and so on. EXAMPLES A typical set of snmp commands in the /etc/rc file will look like the following: snmp contact Network Manager snmp location Bldg 2.
sysconfig NAME sysconfig - display filer configuration information SYNOPSIS sysconfig [ -d | -m | -r | -t | [ -v ] [ slot ] ] DESCRIPTION sysconfig displays the configuration information about the filer. Without any arguments, the output includes the Data ONTAP 5.3 version number and a separate line for each I/O device on the filer.
sysstat NAME sysstat - report filer performance statistics SYNOPSIS sysstat [ interval ] DESCRIPTION sysstat reports filer performance statistics such as the current CPU utilization, the amount of network I/O, the amount of disk I/O, and the amount of tape I/O. By default, sysstat prints a new line of statistics every 15 seconds. The interval argument overrides the default causing sysstat to report once every interval seconds. Use control-C to stop sysstat.
sysstat NFS the number of NFS operations per second during that time; CIFS the number of CIFS operations per second during that time; HTTP the number of HTTP operations per second during that time; Net kB/s the number of kilobytes per second of network traffic into and out of the server; Disk kB/s the kilobytes per second of disk traffic being read and written; Tape kB/s the number of kilobytes per second of tape traffic being read and written; Cache age the age in minutes of the oldest read-on
timezone NAME timezone - set the local timezone SYNOPSIS timezone [ name ] DESCRIPTION timezone sets the system timezone and saves the setting for use on subsequent boots. The argument name specifies the timezone to use. See the system documentation for a complete list of time zone names. If no argument is supplied, the current time zone name is printed. Each timezone is described by a file that is kept in the /etc/zoneinfo directory on the filer.
uptime NAME uptime - show how long system has been up SYNOPSIS uptime DESCRIPTION uptime prints the current time, the length of time the system has been up, and the total number of NFS operations the system has performed since it was last booted. The filer runs uptime automatically once an hour and automatically logs its output to /etc/messages.
useradmin NAME useradmin - add, delete or list administrative users SYNOPSIS useradmin useradd [-c comments] login_name useradmin userdel login_name useradmin userlist [user_name_list] DESCRIPTION The useradmin command can be used to add, delete, or list administrative users. The useradd option is used to add administrative users. The user name can be up to 32 characters long.
version NAME version - display Data ONTAP 5.3 version SYNOPSIS version DESCRIPTION version displays the version of Data ONTAP 5.3 running on the server, and the date when the version was created.
vif NAME vif - create and destroy virtual interfaces SYNOPSIS vif create [ vif_name ] interface_name ... vif destroy vif_name vif stat vif_name [ interval ] DESCRIPTION The vif command creates and eliminates virtual interfaces. It also displays statistics for a specified virtual interface. The vif create command creates a virtual interface. The name of the virtual interface to be created is specified as vifn, where n is a number. Make sure that the specified virtual interface name is not already in use.
vif The following example displays statistics about virtual interface 1: filer> vif stat vif1 Virtual interface (trunk) vif1 e5d In e5c Out In e5b Out In e5a Out In Out 8637076 47801540 158 159 7023083 38300325 8477195 47223431 1617 9588 0 0 634 3708 919 5400 1009 5928 0 0 925 5407 1246 7380 1269 7506 0 0 862 5040 1302 7710 1293 7632 0 0 761 4416 964 5676 920 5388 0 0 721 4188 981 5784 1098 6462 0 0 988 5772 1003 5898 2212 13176 0 0 769 4500
vol NAME vol - commands for managing volumes, displaying volume status, and copying volumes SYNOPSIS vol command argument ... DESCRIPTION The vol commands manage a volume, apply options to a volume, or display the status of one or more volumes. Also, some vol commands copy volumes on the same filer or between two filers. You can use the volume copy feature only if you have purchased the volcopy license and entered the license code for a filer that is involved in a vol copy command.
vol nl pt sv (Dutch) (Portugese) (Swedish) To use UTF-8 as the NFS character set append .UTF-8 vol add volname ndisks[@size] | -d diskname... adds disks to the volume with the name volname. Specify the disks in the same way as for the vol create command. When adding disks to a volume, the filer fills up one RAID group with disks before starting another RAID group. Suppose a volume currently has one RAID group of 12 disks and its RAID group size is 14.
vol the filer is rebooted. If you change your mind after entering this command, you can enter vol online volname before the reboot. vol options volname optname optval sets the option named optname of the volume named vol_name to the value optval. The command remains effective after the filer is rebooted, so there is no need to add vol options commands to the /etc/rc file. Some options have values that are numbers.
vol storing database files. If the filer finds any problems, database instances hang or shut down, and the filer sends error messages to the console to alert you to check the state of the database. snapmirrored off If SnapMirror is enabled, the filer automatically sets this option to on. Set this option to off if you no longer want to use SnapMirror to update the mirror. After you set this option to off, the mirror becomes a regular writable volume.
vol the filers /etc/hosts file. Otherwise, the filer cannot send packets to itself through the loopback address when trying to copy data. The usable disk space of the destination volume must be greater than or equal to the usable disk space of the source volume. Use the df pathname command to see the amount of usable disk space of a particular volume.
vol vol snapmirror status displays whether SnapMirror is enabled. If so, the command displays whether the filer is copying data between the source volume and the mirror, and the percentage of data that has been copied. EXAMPLES vol create vol1 -r 10 20 creates a volume named vol1 with 20 disks. The RAID groups in this volume can contain up to 10 disks, so this volume has two RAID groups. The filer adds the current spare disks to the new volume, starting with the smallest disk.
vol vol copy status displays the status of all the volume copy operations. vol copy abort 1 terminates volume copy operation 1. vol copy throttle 1 10 changes volume copy operation 1 to one-tenth of its full speed.
ypwhich NAME ypwhich - display the NIS server if NIS is enabled SYNOPSIS ypwhich DESCRIPTION ypwhich prints the name of the current NIS server if NIS is enabled. If there is no entry for the server itself in the hosts database, then it prints the IP address of the server. The NIS server is dynamically chosen by the filer.
)LOH )RUPDWV This section contains file formats.
tape NAME tape - information on filer tape interface DESCRIPTION The filer supports up to four local tape drives (tape drives connected directly to the system). The tape drive interface follows a UNIX-like device name allowing use of a rewind, norewind or unload/reload device. The format of a filer tape device name is crstud where: c use n to specify the norewind device, use u to specify the unload/reload device, or no flag to specify the rewind device.
tape nrst0m - no rewind device, format is: EXB-8200C (w/compression) urst0m - unload/reload device, format is: EXB-8200C (w/compression) rst0h - rewind device, format is: EXB-8500 5.0GB nrst0h - no rewind device, format is: EXB-8500 5.0GB urst0h - unload/reload device, format is: EXB-8500 5.
Command ReferenceA-117
+HDGHUV 7DVNV DQG 0DFURV This section contains headers, tasks, and macros.
boot NAME boot - directory of Data ONTAP 5.3 executables SYNOPSIS /etc/boot DESCRIPTION The boot directory contains copies of the executable files required to boot the filer. The download command (see download) copies these files from /etc/ boot into the filers boot block, from which the system boots. FILES /etc/boot directory of Data ONTAP 5.3 executables /etc/boot/netapp-alpha symbolic link to current version of Data ONTAP 5.
crash NAME crash - directory of system core files SYNOPSIS /etc/crash DESCRIPTION If a filer crashes, it creates a core file in the crash directory. The core files are very useful for finding and fixing bugs in Data ONTAP 5.3, so notify Dell technical support of any core files on your filer. See savecore for more details about how core files are saved. FILES /etc/crash/core.* saved core files /etc/crash/core.*-small compact core file.
dgateways NAME dgateways - default gateways list SYNOPSIS /etc/dgateways DESCRIPTION The /etc/dgateways file is used by the routed command to construct a set of potential default gateways. The file is comprised of a series of lines, each in the following format: gateway metric gateway is the name or address of a gateway to be used as a potential default gateway. metric is a metric indicating the preference weighting of the gateway. 1 is the value to use for highest preference, 15 for the least.
dumpdates NAME dumpdates - data base of file system dump times SYNOPSIS /etc/dumpdates DESCRIPTION The dump command (see dump) uses /etc/dumpdates to keep track of which subtrees have been dumped and when. Each line in dumpdates contains the subtree dumped, the dump level, and the creation date of the snapshot used by dump. There is only one entry per subtree at a given dump level. dumpdates may be edited to change any of the fields, if necessary.
exports NAME exports - directories and files exported to NFS clients SYNOPSIS /etc/exports DESCRIPTION The /etc/exports file contains a list of directories and files that are exported by the filer. Changes to this file do not take effect until the filer executes the exportfs command or the filer is rebooted. When the filer is rebooted, it executes the exportfs -a command from the /etc/rc script to export all files and directories listed in the /etc/exports file.

When the client issues an unmount request, the corresponding entry is marked as unused.
serialnum NAME serialnum - system serial number file SYNOPSIS /etc/serialnum DESCRIPTION The file /etc/serialnum should contain the serial number of your machine. The serial number is found on the back of the machine in the lower right hand corner. If the file does not exist on your system, create it and put the machines serial number in it. The file should contain a single line that only has the serial number.
shadow NAME shadow - shadow password file SYNOPSIS /etc/shadow DESCRIPTION The shadow file provides more secure storage for the users password (which would otherwise be in /etc/passwd). When the password field of an entry in /etc/passwd is empty, /etc/shadow must contain a corresponding entry with the same user name but a non-empty encrypted password. username:password: The following list explains the required fields: username The users login name, not more than eight characters.
sm NAME sm - network status monitor directory SYNOPSIS /etc/sm DESCRIPTION The network status monitor provides information about the status of network hosts to clients such as the network lock manager. The network status monitor keeps its information in the /etc/sm directory. The /etc/sm/state file contains an integer that is incremented each time the filer is booted. The /etc/sm/monitor file contains a list of network hosts the filer is monitoring.
sm snap reserve [ vol_name ] | [ vol_name percent ] Sets the size of the indicated volumes snapshot reserve to percent. With no percent argument, prints the percentage of disk space that is reserved for snapshots in the indicated volume. With no argument, the snap reserve command prints the percentage of disk space reserved for snapshots for each of the volumes in the system. Reserve space can be used only by snapshots and not by the active file system.
snapmirror.allow NAME snapmirror.allow - list of filers to which you can replicate volumes from this filer SYNOPSIS /etc/snapmirror.allow DESCRIPTION The /etc/snapmirror.allow file exists on the source filer used for SnapMirror. It contains a list of filers to which you can replicate volumes from the source filer. If the source volume and the mirror exist on the same filer, you still must enter the filer name in this file. In this file, type one filer name per line. EXAMPLE The following snapmirror.
snapmirror.conf NAME snapmirror.conf - configuration file specifying how filers replicate volumes using SnapMirror SYNOPSIS /etc/snapmirror.conf DESCRIPTION The /etc/snapmirror.conf file exists on the filer containing the mirror used for SnapMirror. Each entry of the file specifies the volume to be replicated, an argument for the replication, and the schedule for updating the mirror. Each entry of the /etc/snapmirror.
syslog.conf NAME syslog.conf - syslogd configuration file DESCRIPTION The syslog.conf file is the configuration file for the syslogd daemon (see syslogd). It consists of lines with two TAB separated fields: selector action The selector field specifies the types of messages and priorities to which the line applies. The action field specifies the action to be taken if a message the syslogd daemon receives matches the selection criteria. The selector field is encoded as a facility, a period (.
syslog.conf debug Debug messages used for diagnostic purposes. These messages are suppressed by default. If a received message matches the specified facility and is of the specified level (or a higher level ), the action specified in the action field will be taken. Multiple selectors may be specified for a single action by separating them with semicolon (;) characters. It is important to note, however, that each selector can modify the ones preceding it.
syslog.conf Also see the sample configuration file in /etc/syslog.conf.sample FILES /etc/syslog.conf The syslogd configuration file. /etc/syslog.conf.sample Sample syslogd configuration file.
zoneinfo NAME zoneinfo - time zone information files SYNOPSIS /etc/zoneinfo DESCRIPTION The directory /etc/zoneinfo contains time zone information files used by the timezone command (see timezone). They are in standard UNIX time zone file format as described below. The time zone information files begin with bytes reserved for future use, followed by six four-byte signed values, written in a standard byte order (the high-order byte of the value is written first).
zoneinfo specified in standard time ignores any offset due to Daylight Savings Time. On the other hand, a time specified in wall clock time takes the prevailing value of Daylight Savings Time in to account. Finally there are tzh_ttisgmtcnt GMT/local indicators, each stored as a one-byte value; they tell whether the transition times associated with local time types were specified as GMT or local time.

autosupport NAME autosupport - email notification daemon SYNOPSIS Data ONTAP 5.3 is capable of sending email notification to other designated addressees in certain situations. The email contains useful information to help them solve or recognize problems quickly and proactively. The system can also be configured to send a short alert notification containing only the reason for the alert to a separate list of recipients.
autosupport 7. If a disk shelf reports errors, notification is sent with SHELF_FAULT!!!. This event also sends the short note mail. 8. If one of the power supplies in the filer fails, notification is sent with POWER_SUPPLY_DEGRADED!!!. This event also sends the short note mail. 9. If the system shuts down because it has detected that the temperature inside the filer is too high, notification is sent with OVER_TEMPERATURE_SHUTDOWN!!!. This event also sends the short note mail. 10.
autosupport 18. Output from sysconfig -r 19. The /etc/messages file The autosupport feature is manipulated through the options command (see options). The options choices are: autosupport.enable: on,off autosupport.mailhost: Comma-separated list (no spaces) autosupport.to: Comma-separated list (no spaces) autosupport.noteto: Comma-separated list (no spaces) autosupport.from: Local user name autosupport.doit: text word describing reason autosupport.enable: Default is on.
autosupport autosupport.from: Default is autosupport. Enter a user name designated as the sender of the autosupport mail. This allows replies to the mail to be received by a responsible representative at the site. options autosupport.from sysadm autosupport.doit: This is a trigger to send the email out. The text word argument to this option is sent in the email subject line. This is used to identify the reason for the notification.
DNS NAME DNS - Domain Name System DESCRIPTION Domain Name Service provides information about hosts on a network. This service has two parts: a resolver which requests information and a nameserver which provides it. Data ONTAP 5.3 supports only the resolver. When the filer needs to resolve a host address, it first looks at the /etc/nsswitch.conf (see nsswitch.conf) file to get the order in which various name services are to be consulted.
NIS NAME NIS - NIS client service DESCRIPTION The NIS client service provides information about hosts, user passwords, user groups and netgroups on a network. In NIS terminology, each of the above is referred to as the map and the specific information being looked up is called the key. For example, the hosts map is like the /etc/hosts file; it provides a translation from host names to IP addresses.
rmt NAME rmt - remote magtape protocol module SYNOPSIS /etc/rmt DESCRIPTION /etc/rmt is a special command that can be used by remote computers to manipulate a magnetic tape drive over a network connection; for example, the UNIX dump and restore commands often can either use /etc/rmt to access a remote tape, or have rdump and rrestore variants that can do so. /etc/rmt is normally run by the rshd daemon (see rshd) as a result of a remote machine making a request to rshd to do so.
rmt The protocol is comprised of the following commands, which are sent as indicated - no spaces are supplied between the command and its arguments, or between its arguments, and \n indicates that a newline should be supplied: Odevice\nmode\n Open the specified device using the indicated mode.
rmt 5 rewind the tape 6 rewind and unload the tape The return value is the count parameter when the operation is successful. Any other command causes /etc/rmt to close the connection. DIAGNOSTICS All responses are of the form described above.
rquotad NAME rquotad - remote quota server DESCRIPTION The filer supports the remote quota service that allows NFS clients to determine their quota allocation on the server.
rshd NAME rshd - remote shell daemon DESCRIPTION The filer has UNIX-compatible remote shell capability that enables you to execute certain filer commands from a UNIX command line or shell script. It also enables you to use a remote shell application on a PC to enter filer commands. The /etc/hosts.equiv file controls which hosts have access to the filer remote shell. The hosts listed in the /etc/hosts.equiv file are called trusted hosts.
snmpd NAME snmpd - snmp agent daemon DESCRIPTION The filer supports an SNMP version 1 compatible agent that provides support for both the MIB-II management information base for TCP/IP based internets as well as a Dell Custom MIB. A number of user configurable options for the SNMP agent can be set and queried from the console using the snmp command (see snmp). Due to weak authentication in SNMP version 1, SetRequest commands that allow the remote setting of configuration variables have been disabled.
snmpd raid Information on RAID equivalent to the output of the sysconfig -r command (see sysconfig).
syslogd NAME syslogd - log system messages DESCRIPTION The syslogd daemon logs system messages to the console, log files and other remote systems as specified by its configuration file, /etc/syslog.conf. The syslogd daemon reads its configuration file when it starts up during the boot procedure, or within 30 seconds after the /etc/syslog.conf file is modified. For information on the format of the configuration file, see syslog.conf. If /etc/syslog.
