The commands in “Commands for Linux X9000 clients and file serving nodes” (page 156) can be executed on file serving nodes and/or Linux X9000 clients. Any user can run these commands. All commands are run from the working directory /usr/local/ibrix/bin. Command syntax Names.
2 X9000 File Serving Software commands This chapter lists commands used to configure and manage X9000 File Serving Software. The commands must be run on the Fusion Manager host. ibrix_activedirectory Configures and lists Active Directory settings. Description Active Directory settings must be configured on the Fusion Manager to allow Windows X9000 clients to query the Active Directory server when reading or writing on a file serving node.
Option Description -S Configures static user mapping. -W WIN_USER_NAME Sets the “Unknown” Windows user, who takes ownership of files when a mapping cannot be resolved. -d DOMAIN_NAME Identifies a fully qualified Active Directory domain name. -i DOMAIN_CONTROLLER_IP The domain controller IP address. -l Displays Active Directory settings on this Fusion Manager. -p PROXY_PASSWORD Sets the Active Directory proxy password.
ibrix_auth Configures Active Directory or Local Users and Groups authentication for CIFS, FTP, and HTTP shares. Description The ibrix_auth command configures Active Directory or Local Users and Groups as the authentication method for users accessing CIFS, FTP, or HTTP shares.
Option Description -h HOSTLIST A list of file serving nodes. -n DOMAIN_NAME Specifies the domain name for Active Directory authentication. -i Displays current information about authentication. -t Modifies the authentication settings. -? Shows the usage for this command.
ibrix_av Manages miscellaneous Antivirus operations. Description The ibrix_av command is used to start a cluster-wide update of Antivirus definitions and to display or delete Antivirus statistics. You can schedule periodic updates of the virus definitions. The cluster connects with external virus scan engines, which have the current definitions, and the definitions are updated on the cluster nodes as needed.
ibrix_avconfig Configures Antivirus operations on an X9000 cluster. Description The ibrix_avconfig command can be used to enable or disable Antivirus operations on file systems, to add the virus scan engines running the Antivirus software, to configure exclusions on directories, and to configure other policies. To configure the Antivirus feature on a cluster, complete these steps: 1. Add the external virus scan engines to be used for virus scanning. These systems run the Antivirus software.
The -G option specifies the policy that determines which file operations trigger AV scans. There are three policies: • O — Scan on open. • C — Scan on close. • B — Scan on open and close. The -k option specifies the file sharing protocol affected by the scan policy. Currently, only the CIFS protocol is supported. Add exclusions on the specified directory: ibrix_avconfig -a -E -f FSNAME -P DIR_PATH {-N | [-x FILE_EXTENSION] [-s FILE_SIZE]} Exclusions specify files to be skipped during Antivirus scans.
Option Description -g Updates the Antivirus unavailable policy. -k PROTOCOL Specifies a file sharing protocol for scan policies. -l Lists the Antivirus configuration. -p PORTNUMBER Specifies the port number of an external scan engine. -r Removes an existing item from the Antivirus configuration. -s FILE_SIZE Specifies the file size limit (in MB) for exclusions. -u Updates an item in the Antivirus configuration.
ibrix_caseinsensitive Manages case insensitivity on a file system or directory. Description By default, X9000 file systems and directories follow POSIX semantics and file names are case-sensitive for Linux/NFS users. (File names are always case-insensitive for Windows clients.) If you prefer to use Windows semantics for Linux/NFS users, you can make a file system or subdirectory case-insensitive. Doing this prevents a Linux/NFS user from creating two files that differ only in case (such as foo and FOO).
ibrix_certificate Manages SSL certificates. Description Servers accepting FTPS and HTTPS connections typically provide an SSL certificate that verifies the identity and owner of the web site being accessed. You can add your existing certificates to the cluster, enabling file serving nodes to present the appropriate certificate to FTPS and HTTPS clients. X9000 Software supports PEM certificates. When you add an SSL certificate file to the cluster, the file must contain both the certificate contents (the .
Option Description -e Exports a certificate. -i Shows information about a certificate. -m Modifies a certificate. -p CERTPATH Specifies the location of the certificate file. -? Shows the usage for this command. NOTE: The -m and -S SETTINGLIST options shown in the command usage message are not currently supported.
ibrix_chassis Display information about the chassis in an X9720/X9730 system, or unregister a chassis. Description The chassis in an X9720/X9730 system is registered automatically for hardware monitoring. The ibrix_chassis command displays information about registered chassis or about servers registered in a chassis. You can also use the command to unregister a chassis.
ibrix_cifs Manages CIFS shares. NOTE: Be sure to use the ibrix_cifs command located in /bin. The ibrix_cifs command located in /usr/local/bin/init is used internally by X9000 Software and should not be run directly. Description CIFS is the file-sharing protocol used in Windows-based networks. Use the ibrix_cifs command to configure CIFS shares. You can configure the following options when creating a share: • Default modes for creating files and directories in the share.
Options Option Description -A ALLOWCLIENTIPSLIST Lists client IP addresses that are allowed access to the share. Use commas to separate the IP addresses, and enclose the list in quotes (for example, ibrix_cifs -A “192.186.0.1,102.186.0.2/16”). The default is "", which allows all IP addresses. -D SHAREDESCRIPTION Describes the share. -E DENYCLIENTIPSLIST Lists client IP addresses that are denied access to the share.
ibrix_cifsconfig Configures global settings for CIFS. Description The ibrix_cifsconfig command configures global settings for CIFS operations. The settings apply to all CIFS shares configured in the cluster. Synopsis Configure CIFS settings: ibrix_cifsconfig -t [-S SETTINGLIST] [-h HOSTLIST] For the -S SETTINGLIST option, enclose the list of settings in quotation marks, and use commas to separate the settings.
See also ibrix_cifs ibrix_cifsconfig 21
ibrix_cifsmonitor Monitors CIFS services on file serving nodes. Description The ibrix_cifsmonitor command configures monitoring for the following CIFS services: • lwreg • dcerpc • eventlog • lsass • lwio • netlogin • srvsvc If the monitor finds that a service is not running, it attempts to restart the service. If the service cannot be restarted, that particular service is not monitored.
ibrix_cifsperms Manages user and group permissions for CIFS shares. Description The ibrix_cifsperms command adds a user or group to a CIFS share and assigns share-level permissions. You can also use the command to modify or delete existing share-level permissions, or to display the current share-level permissions. The share level permissions are fullcontrol, read, or change. NOTE: Permissions on a CIFS share managed by the MMC cannot be modified by the X9000 management console GUI or CLI.
ibrix_client Performs management and control procedures for X9000 clients. Description ibrix_client enables the following X9000 client procedures: • Registers a Linux X9000 client with a Fusion Manager. Clients that are to communicate with multiple management consoles must be registered on each console. (To register a Windows X9000 client, use the Windows X9000 client GUI.) • Sets a preferred user interface for an X9000 client. (To prefer a user interface for a hostgroup, use ibrix_hostgroup.
Options Option Description -A Assigns a preferred NIC. -D DESTSERVER Deletes the network interface preference established between the source client and the destination server. -a Adds an X9000 client. -d Deletes a client from the configuration database. -e IPADDRESS Specifies the IP address for a client. -h CLIENTLIST One or more clients (specify as CLIENT1,CLIENT2,CLIENT3,...). -i Provides detailed information for one or more clients. -l Lists clients.
ibrix_cluster Registers a remote cluster for remote replication. Description The source and target clusters of a remote replication configuration must be registered with each other before remote replication tasks can be created. Use ibrix_cluster -r on the target cluster to register the source cluster before creating a remote replication export with ibrix_crr_export. Use ibrix_cluster -r on the source cluster to register the target cluster before starting a remote replication task with ibrix_crr.
ibrix_clusterconfig Sets or displays cluster configuration parameters. Description Configures cluster configuration settings such as the default gateway and time zone. The settings are used during cluster setup and can also be used to update the configuration of existing systems. Synopsis Show cluster-wide configuration parameters: ibrix_clusterconfig -i -P Set cluster configuration parameters: ibrix_clusterconfig -c -P PARAM1=VALUE1[,...
ibrix_clusterconfig -d -L DEV -I ADDRESS Show OS parameters and tunings: ibrix_clusterconfig -i -O Create or update an OS parameter: ibrix_clusterconfig -c -O KEY=VALUE,[...KEY=VALUE] Delete/reset an OS parameter: ibrix_clusterconfig -d -O KEY List OS parameters and defaults: ibrix_clusterconfig -Q Synchronize parameters on file serving nodes: ibrix_clusterconfig -s [-P] [-O] [-o keyword] [-h HOSTLIST] Use -P to synchronize cluster parameters such as DNS and NTP. Use -O to synchronize OS tunings.
ibrix_collect Collects information from X9000 cluster nodes for diagnosis by HP Support. Description This command collects relevant information from X9000 systems for diagnosis. You can invoke the collection manually using ibrix_collect or the GUI, or it can be invoked automatically by a system crash. When you invoke the collection manually, you can specify a name for the collection. A collected data set includes logs and output from specific operating system and X9000 commands.
Delete all data collection sets: ibrix_collect -F Show details for the specified data collection: ibrix_collect -v -n NAME The details include the description, state, initiator, and time of invocation. List the details of all data collections: ibrix_collect -l For each collection, the output reports the collection name, description, state, time of invocation, and initiator. List the ibrix_collect configuration: ibrix_collect -i Options 30 Option Description -C options Configures ibrix_collect.
ibrix_crr Starts and stops the replication process and monitors the state of replication activity. Description The Continuous Remote Replication service (CRR) provides a transparent method to replicate changes in a source file system on one cluster to a target file system on either the same cluster or a second cluster. The remote replication service has two modes: continuous and run-once. For detailed information about these modes, see the HP IBRIX X9000 Network Storage System File System User Guide.
Omit the -o option to start a continuous replication task. A continuous replication task does an initial full synchronization and then continues to replicate any new changes made on the source. Continuous replication tasks continue to run until manually stopped by the user. Start an intra-cluster remote replication task: ibrix_crr -s -f SRC_FSNAME [-o [-S SRCDIR]] -F TGT_FSNAME [-P TGTDIR] The command starts a continuous or run-once intra-cluster replication task for file system SRC_FSNAME.
Use -h to limit the output to the specified host. When the command is run from a target, the -C option identifies the source cluster and is required. It is optional when the command is run from the source cluster. Options Option Description -C TGT_CLUSTERNAME The remote cluster name. -C SRC_CLUSTERNAME The source cluster name. When a command is run from the target cluster, this argument is required. –F TGT_FSNAME The target file system. -K Forcefully stop a replication task.
ibrix_crr_export Configures a target export for continuous remote replication (CRR). Description This command exports a target file system and directory for remote replication. Before remote replication can take place, you must create a mapping between the source cluster and the target file system that receives the replicated data. This mapping ensures that only the specified source cluster can write to the target export (exported file system and directory).
ibrix_crr_nic Identifies server assignments for the servers and corresponding NICs that handle replication requests. Description If you are replicating a file system to a remote cluster, you can use ibrix_crr_nic on the target cluster to select or modify the servers that handle replication requests and the corresponding NICs that carry replication traffic in the cluster. The default server assignments are: • Use all servers that have the file system mounted. • Use the cluster NIC on each host.
Options Option Description -D Restores the default server assignments (automatically use all servers and the cluster network interface on each server). -P ASSIGNMENT_ID1 [,...,ASSIGNMENT_IDn] Server assignment ID. -a Creates a server assignment. A previous server assignment for the same export must not exist, or must be removed before a new server assignment is created. —f FSNAME An exported file system. -h HOSTLIST The servers to use for remote replication.
ibrix_datavalidation Performs a data validation scan of a file system or subdirectory configured for data retention Description To ensure that WORM and retained files remain unchanged, it is important to run a data validation scan periodically.
ibrix_dbck Ensures that information maps on hosts are consistent with the configuration database. NOTE: ibrix_dbck should be used only under the direction of HP Support. Description Hosts (file serving nodes and X9000 clients) maintain information about a file system based on information that they obtain from the configuration database. If a host’s information about a file system becomes outdated, the host cannot access the file system or communicate with other hosts about the file system.
ibrix_edquota Sets and manages file system quotas for users, groups, and directory trees. Description The ibrix_edquota command sets, lists, and deletes storage quotas for users or groups on a specific file system. It also sets directory tree quotas, which limit the amount of storage and the number of files that can be created on a file system located at a specific directory tree. By default, quotas are not set. The recommended order for handling quotas is as follows: 1.
If you are creating multiple directory tree quotas, you can import the quotas from a file. The system then uses batch processing to create the quotas. If you add the quotas individually, you will need to wait for ibrix_onlinequotacheck to finish after entering each ibrix_edquota command.
Options Option Description -C Sets the grace period for a file system. The default is seven days. -D Deletes user, group, or directory tree limits. -G Specifies all groups with quota settings. -I SOFT_FILES Sets the soft limit on the number of files. -K INODES_GRACE_TIME Specifies the number of Hours/Days/Weeks/Months to set as the grace period for the inode limit (for example, 10H/1D/2W/2M). -M SOFT_MEGABYTES Sets the soft limit on the megabyte allocation. –T All directory trees.
ibrix_evacuate Evacuates all files from the specified segments to other segments in the same file system. Description Before retiring storage, move, or evacuate, all files from the segments on that storage to other segments in the same file system. If segments with adequate space are not available, use ibrix_fs to extend the file system. The evacuation operation is transparent to users or applications accessing the file system.
ibrix_event Sets up email and SNMP notifications of cluster events, displays event messages, and removes event messages from the events table. Description Use ibrix_event to set up two types of event notifications: • Email notification, which sends to one or more addresses an email containing the event, the originating server, the severity level, a timestamp, an autogenerated number, and the Fusion Manager name. • SNMP notification, which sends an SNMP trap to one or more trapsinks.
Before sending a test message to the email address, notifications must be turned on. If the address is valid, the command signals success and sends an email containing the settings to the recipient. If the address is not valid, the command returns an address failed exception. Remove events from the events table: ibrix_event -p [-o DAYS_COUNT] Events are removed starting with the oldest events. The default is to remove the oldest seven days of messages.

ibrix_exportfs Maintains the list of NFS-exported file systems and specifies file-system access for X9000 clients. Description ibrix_exportfs makes local directories available for NFS clients to mount. The Fusion Manager manages the table of exported file systems and distributes the information to local /etc/exports files. All entries are automatically re-exported to NFS clients and, optionally, to the file serving node standbys. A file system must be mounted before it can be exported.
ibrix_exportfs -U -f FSNAME -p CLIENT1:PATHNAME1,CLIENT2:PATHNAME2,.. Options Option Description -U Unexports the named file system. -b Excludes the file serving node standby from the export. -c Specifies file-system access for an X9000 client. -f FSNAME A file system. -h HOSTNAME or HOSTLIST A file serving node or a list of file serving nodes exporting a file system. -l Lists all NFS export entries, or lists entries on a named host. -o “OPTIONS ” Linux exportfs options.
ibrix_fm Controls an agile Fusion Manager configuration. Description Typically, the Fusion Manager is installed on all file serving nodes when the cluster is installed. The Fusion Manager is active on one node and passive on the other nodes. This is called an agile Fusion Manager configuration. An agile Fusion Manager can be in one of the following modes: • active. In this mode, the Fusion Manager controls console operations.
ibrix_fm -l Options Option Description -A With the exception of the local node running the active Fusion Manager, moves all instances of the Fusion Manager to the specified mode. -B Backs up the Fusion Manager configuration. -I Specifies an IP address. -R Registers a Fusion Manager. -a Specifies the IP address of the cluster virtual interface. -c Adds information about a virtual interface to the Fusion Manager configuration.
ibrix_fm_tune Sets or resets configuration tuning parameters on the Fusion Manager. Description CAUTION: Manager. This command sets or resets the configuration tuning parameters on the Fusion The default values for the Fusion Manager tuning parameters are suitable for most cluster environments. Changing parameter values can alter file-system performance. HP recommends that you exercise caution before implementing any changes, or do so only under the guidance of HP technical support.

ibrix_fs Creates, extends, and manages file systems. Description ibrix_fs is used to: • Create a file system from physical or logical volumes. • List information about file systems (including snapshot file systems). • Extend a file system by adding new segments. • Delete a file system. • Migrate segments to another file serving node. • Enable or disable export control on a file system. • Disable 32-bit mode on a file system. • Assign or unassign a standby server.
Create a file system from the specified physical volumes in one step: ibrix_fs -c -f FSNAME -p PVLIST [-a] [-q] [-o OPTION1=VALUE1,OPTION2=VALUE2,...] [-t TIERNAME] The file system is created from the physical volumes in PVLIST. One volume group is created per physical volume. Segments are then created from the volume groups and assigned to file serving nodes in a round-robin manner.
-o compat=no Enable 64-bit mode on the file system. -o compat=yes,maxsegs=n Create a 32-bit file system and specify the maximum number of segments to allow in the file system. The valid values for maxsegs are 15, 31, 63, 127, and 255. If none of these options are specified, the new file system is created with quotas disabled, with no mountpoint, and with 32-bit mode compatibility enabled.
Migrate segment ownership Use the following commands to migrate ownership of segments to another file serving node. Migration does not move segments from one physical location to another. Instead, the ownership is recorded on the physical segment itself. Migrate ownership of segments to a new host and update the source host: ibrix_fs -m -f FSNAME -s LVLIST -h HOSTNAME [-M] [-F] [-N] The segments in LVLIST on file system FSNAME are migrated to the new host. To force the migration, include -M.
ibrix_fs -w -f FSNAME Assign or delete a standby server for the specified segments Identify a file serving node as the standby for the specified segments: ibrix_fs -b -f FSNAME -s LVLIST -h HOSTNAME The command assigns HOSTNAME as the standby for the segments in LVLIST on file system FSNAME. To identify a standby server for all segments on a file serving node, use the following command, where HOSTNAME2 is the standby for HOSTNAME1.
Option Description compat=yes|no. Declares whether this file system is 32-bit compatible. maxsegs=n. Defines the number of segments per file system in 32-bit file systems. n can be set to 15, 31, 63, 127, or 255. Data retention options are also set with -o. -p PVLIST A list of one or more physical volume names, expressed as a comma-separated list (for example, d1,d2,d3) or a range (for example, d[1-3]). -q Enables quotas on a file system.
ibrix_fs_ops Manages directory tree quota entries. IMPORTANT: The ibrix_fs_ops command is deprecated in the X9000 File Serving Software 6.0 release. Use the ibrix_edquota command to create, delete, or view directory tree quotas. Description Directory tree quotas apply to a file system located at a specific directory tree. Use the ibrix_fs_ops command to create, delete, or view directory tree quotas.
ibrix_fs_tune Overrides the default file allocation behavior on file serving nodes and clients. Description File allocation policies are set per file system on each file serving node and on X9000 clients. The policies define the following: • Preferred segments. The segments where a file serving node or X9000 client creates all new files and directories. • Allocation policy.
Deprecated segment preferences and allocation policies IMPORTANT: HP recommends that you do not use these options. They are currently supported but will be removed in a future release. Name Description Comment AUTOMATIC Lets the X9000 Software select the allocation policy. Should be used only on the advice of HP support. DIRECTORY Allocates files to the segment where its parent directory is located.
Reset the specified hosts or hostgroups to the default allocation policy for the file system: ibrix_fs_tune -f FSNAME {-h HOSTLIST|-g GROUPLIST} -p -U Prefer a pool of segments for the specified hosts or hostgroups: ibrix_fs_tune -f FSNAME {-h HOSTLIST|-g GROUPLIST} -s LVNAMELIST The segments to be included in the pool are specified by logical volume name (LVNAMELIST). To prefer a pool of segments for NFS/CIFS clients, specify only NFS/CIFS servers in the HOSTLIST.
Options Option Description -N NFS readahead Specifies the number of KB that X9000 Software pre-fetches under NFS. The default value is 128 KB. -O Sets one or more allocation policy tuning options. -P prealloc Sets the number of KB a file system pre-allocates to a file. Default: 256 KB. -R Sets allocation policy for directory segments only. -S SEGMENT_NUMBER Specifies a segment.
ibrix_fsck Analyzes inconsistencies in a file system. Description CAUTION: Do not run ibrix_fsck in corrective mode without the direct guidance of HP Support. If run improperly, the command can cause data loss and file system damage. CAUTION: Do not run e2fsck or any other off-the-shelf fsck program on any part of a file system. Doing so will damage the file system. The ibrix_fsck command command can detect and repair file system inconsistencies.
The command can be run on file system FSNAME or optionally only on segment LVNAME. This phase can be run with a specified block size and an alternate superblock number. For example: ibrix_fsck -p 1 -f ifs1 -B 4096 -b 12250 NOTE: If phase 1 is run in analytic mode on a mounted file system, false errors can be reported. Run phase 2: ibrix_fsck -p 2 -f FSNAME [-s LVNAME] [-c] [-o "options"] The command can be run on the specified file system or optionally only on segment LVNAME.
ibrix_ftpconfig Manages configuration profiles for the FTP service. Description A configuration profile specifies a set of global FTP parameters that are in effect on the file serving nodes listed in the profile. The vsftpd service starts on these nodes when the cluster services are started. Only one configuration profile can be in effect on a particular node. When you create an FTP share, you will need to associate it with a configuration profile.
Option Description -S SETTINGLIST Specifies the settings that are to be applied to a configuration profile. Use a comma to separate the settings, and enclose the settings in quotation marks, such as “passive_enable=true,maxclients=200,...”. To see a list of available settings for the share, use ibrix_ftpconfig -L. -a Adds a configuration profile. -d Deletes a configuration profile. -h HOSTLIST Specifies one or more file serving nodes.
ibrix_ftpshare Manages FTP shares. Description An FTP share provides access to data on X9000 software file systems. FTP clients access the shares using standard FTP and FTPS protocol services. The ibrix_ftpshare command can be used to add a share to an existing file system. You can create multiple shares having the same physical path, but with different sets of properties, and then assign users to the share that is appropriate for their usage. NOTE: The file system must be mounted when you add the share.
Use -v 1 to display detailed information. List the valid settings for a share: ibrix_ftpshare -L Options Option Description -I IPaddrs:Port Specifies the IP addresses/ports assigned to this share. -L Lists valid FTP share settings. -S SETTINGLIST Specifies the settings to apply to an FTP share. Use a comma to separate the settings, and enclose the settings in quotation marks, such as “browseable=true,readonly=true,...”.

ibrix_hba Discovers HBAs, identifies standby pairings of HBA ports, monitors HBA ports for failure, deletes HBAs from the configuration database, and lists information about HBAs. Description ibrix_hba sets up HBA monitoring. When a monitored HBA port fails, the Fusion Manager fails the host over to its standby if a standby has been declared and if automated failover is turned on. The -b option identifies two multipath HBAs that have been set to operate as a failover pair.
Option Description -b Identifies two ports as a standby pair. -d Deletes an HBA port definition. -h HOSTNAME or HOSTLIST One or more file serving nodes. -l For each host, displays its WWNN, WWPN, backup WWPN, and whether HBA monitoring is turned on. -m Turns on HBA monitoring. -p PORT Specifies the port number used for HBA monitoring.
ibrix_health Generates health reports for cluster components and X9000 clients. Description The ibrix_health command includes options specific to X9720/X9730 systems and other options for file serving nodes and X9000 clients. For X9720/X9730 systems, ibrix_health generates a detailed or summary health report for storage, chassis, or servers registered to a chassis. For file serving nodes and X9000 clients, ibrix_health runs a set of health checks on all hosts or the specified hosts and reports the results.
-t SCRIPTNAMELIST: Runs the specified scripts and include them in the health report. Display a detailed health report for file serving nodes or X9000 clients: ibrix_health -i -h HOSTLIST [-f] [-b] [-s] [-v] [-t SCRIPTNAMELIST] The options are: –h HOSTLIST: Runs health checks on the specified file serving nodes and X9000 clients. -f: Reports only hosts that failed a test. -b: Includes standbys for file serving nodes. -s: Includes details about the file system and segments.
