Troubleshooting procedures 7 Installation Procedure for Linux The installation and configuration of the StorNext File System (StorNext FS) on Linux includes the following procedures.
SNFS Prerequisites Consider these prerequisites when working with Linux servers and clients: • • Kernel requirements Multiple LUN support Kernel Requirements StorNext FS supports two Linux operating systems, RedHat and SuSE, that have separate kernel requirements. RedHat Linux - Kernel Requirements To run StorNext FS on RedHat Linux, you must use one of these kernels: • • For uniprocessor and multiprocessor systems, RedHat Linux 7.3, kernels 2.4.17-2.4.
SNFS SuSE Linux - Kernel Requirements To run StorNext FS on SuSE Linux, use this procedure to determine and install the required kernels, including compilers. Step 1 Check to see whether the compiler was installed at the same time as the rest of the system. a. Query the kernel. Enter: # rpm -qi `rpm -qa | grep k_` Output similar to the following displays. Name: k_smp Relocations:(not relocateable) Version: 2.4.
SNFS b. Query gcc. Enter: # rpm -qi `rpm -qa | grep gcc` Output similar to the following displays. Name: Version: Release: Install Date: Group: Size: Packager: Summary: Description: SuSE series: Distribution: Name: Version: Release: Install Date: Group: Size: Packager: Summary: Description: Name: Version: Release: Install Date: Group: Size: Packager: Summary: Description: gcc-info Relocations:(not relocateable) 3.
SNFS Step 2 Install the base system. a. Select the language in which to run the install. A system page displays with an area titled “Timezone” and a place to change the “Software”. b. Click on “Software” and then click “Detailed Selections”. A two-paned window displays with check boxes on the left pane and list of packages on the right pane. c. On the left side, only click the box that is not already checked and click Accept. d. Complete the installation.
SNFS Step 7 Change directory (cd) into /usr/src and create a link to the kernel source. Enter: # cd /usr/src # ln -s linux-2.4.19.SuSE linux-2.4 Step 8 Change directory (cd) into linux-2.4 and delete any leftover config files in the directory. Copy the original config file into the current directory and re-name the .cfg file. Enter: # cd linux-2.4 # cp /boot/vmlinuz.config /usr/src/linux-2.4/.config Step 9 Configure the kernel, build the kernel, build the modules and install the modules.
SNFS Step 12 Edit the /boot/grub/menu.lst file so the kernel can be booted. Make edits to reflect the new kernel configuration parameters. file /boot/grub/menu.lst before changes: title linux kernel (hd1,0)/boot/vmlinuz root=/dev/sdb1 initrd (hd1,0)/boot/initrd title floppy root (fd0) chainloader +1 vga=791 file /boot/grub/menu.
SNFS For example: alias parport_lowlevel parport_pc alias scsi_hostadapter aic7xxx alias eth0 eepro100 alias eth1 e1000 alias scsi_hostadapter1 qla2300 options scsi_mod max_scsi_luns=128 Step 2 Create a new initial RAM disk file by using the mkinitrd command. For example: # cd /boot mkinitrd -f initrd-2.4.18.17.7.xsmp.img 2.4.18-17.7.xsmp Step 3 Reboot the system. Install StorNext FS on Linux NOTE For upgrade instructions, refer to the StorNext Management Suite Release Notes.
SNFS • If you use a Uniprocessor system, install the server and client files, including the word up in the filenames. For example: # rpm -ivh cvfs-server.7.3_2417up-2.1.1-62.i386.rpm # rpm -ivh cvfs-client.7.3_2417up-2.1.1-62.i386.rpm • If you use a Multiprocessor system, install the server and client files, including the word smp in the filenames. # rpm -ivh cvfs-server.7.3_2419smp-2.1.1-62.i386.rpm # rpm -ivh cvfs-client.7.3_2418smp-2.1.1-62.i386.
SNFS Step 10 Return to Step 1 to install StorNext FS on another Linux machine. Obtain License for Linux Server The StorNext FS server must have a valid license. To obtain the license file: Step 1 Verify that /etc/hosts has a proper entry for the system name. NOTE In certain situations, the Linux installation program attaches the system name to 127.0.0.1, instead of an entry for the Ethernet card. The following example illustrates this situation for /etc/hosts with the system name, snpc4: 127.0.0.
SNFS Label Drives on Linux You must label each drive to be used by StorNext FS. A new drive needs to be labeled only one time. Drive labeling can be performed from any StorNext client that has a Fibre Channel connection to the drive. CAUTION The process of disk labeling re-partitions the drives. If you select an incorrect drive, you may lose data. To label a drive: Step 1 From the system prompt on any StorNext FS client, display a list of connected drives.
SNFS Step 3 Create /usr/cvfs/config/cvlabels from the copy of the StorNext FS label file example. Enter: # /usr/cvfs/bin/cvlabel -c > /usr/cvfs/config/cvlabels The created file displays an entry for disk located by the cvlabel command. CvfsDisk_UNKNOWN sdb CvfsDisk_UNKNOWN sdc CvfsDisk UNKNOWN sdd Step 4 Edit /usr/cvfs/config/cvlabels file to provide a unique name for each drive used by StorNext FS. In this example, _UNKNOWN has been changed to a sequential list.
SNFS Configure StorNext FS Software on Linux To configure the StorNext FS software on a Linux machine, you have to configure the software on the StorNext FS server and StorNext FS clients. Server Configuration Step 1 Create a StorNext FS-managed file system by copying /usr/cvfs/examples/ example.cfg to /usr/cvfs/config/.cfg where file_system_name is a unique, descriptive name. For example: # cd/usr/cvfs/config # cp ../examples/example.cfg ./projA.cfg NOTE Step 2 The example.
SNFS DISK section - Identifies the disk type to be assigned to a disk drive that is labeled and available for StorNext FS. A disk type describes a category of disks with a capacity specified in number of sectors. The following parts comprise a disk definition: • The required keyword Disk preceded by the open bracket symbol ( [ ) and followed by the closed bracket symbol ( ] ).
SNFS Examples of stripe groups appear in the configuration file. • Find the stripe group named RegularFiles. • Edit the Node entries so that all the disk names are listed, with each entry followed by a space and then the stripe order number (0, 1, 2, etc.). For example: [StripeGroup RegularFiles] Status UP Read Enabled Write Enabled StripeBreadth 16 Node CvfsDisk12 0 Node CvfsDisk13 1 Step 3 Save the configuration file. NOTE Step 4 Make sure you have a .
SNFS Step 7 In the fsmlist file, add the names of all of the StorNext File Systems. Step 8 Create a nameserver list by copying the /usr/cvfs/examples/fsnameservers.example to the /usr/cvfs/config/fsnameservers file. Enter: # cd /usr/cvfs/config # cp ../examples/fsnameservers.example ./fsnameservers Step 9 In the fsnameservers file, add the host IP address or name of the StorNext FS server. For more information about failover environments, refer to the cvfs_failover man page.
SNFS Mount StorNext FS on Linux To mount StorNext FS: Step 1 Create the StorNext FS mount directory. This is the path by which users access the file system. For example: # mkdir /usr/clips # chmod 777 /usr/clips Step 2 Add the StorNext FS name to the /etc/fstab file. Use cvfs as the file system type. For example: # projA /usr/clips/ cvfs rw,threads=6 0 0 When the StorNext FS server starts up or reboots, StorNext FS automatically mounts any file systems listed in the /etc/fstab file.

Obtain license for the server. Label the disk drives. Configure the StorNext FS software. Mount StorNext FS.
SNFS Topic Refer to Chapter On Solaris: • • • • • 6 Install StorNext FS. Obtain license for the server. Label the disk drives. Configure the StorNext FS software. Mount StorNext FS. Troubleshooting procedures 7 Installation Procedure for Solaris The installation and configuration of the StorNext File System (StorNext FS) on Solaris includes the following procedures.
SNFS Install StorNext FS on Solaris NOTE For upgrade instructions, refer to the StorNext Management Suite Release Notes. To install StorNext FS on Solaris: Step 1 Designate one Solaris machine as the StorNext FS server. Step 2 Log onto the machine as root. Step 3 Insert the StorNext File System CD into the drive and wait for the hardware to access it. Step 4 Run the pkgadd utility to start the Solaris installation. # pkgadd -d Step 5 Select the package for ADICcvfs.
SNFS Obtain License for Solaris Server The StorNext FS server must have a valid license. To obtain the license file: Step 1 Run the StorNext FS host identifier utility. Enter: # usr/cvfs/bin/cvfsid The output looks similar to this. 690CB94A sun 1 The hexadecimal number is unique to the server and host_name should match the server’s host name. This number is known as the ID string. Step 2 Email the ID string and the number of client machines to ATAC at support@adic.com.
SNFS Step 2 From the output information, identify any drives that are unused or do not have a recognized Volume Type and write down their associated device names. CAUTION Step 3 Identify any drives that already contain a recognized Volume Type. Do not write a label to these drives or you may lose data. Create /usr/cvfs/config/cvlabels from the copy of the StorNext FS label file example. Enter: # cd/usr/cvfs/config # cp ../examples/cvlabels.example .
SNFS Step 4 Edit /usr/cvfs/config/cvlabels so that it contains a list of StorNext FS label names that correspond to the device names of the drives captured in Step 2. You can create any convention for the label names. For example, if a site consists of 12 Fibre Channel drives, you can use CvfsDisk[n] for each label name. Replace [n] with a decimal number starting at 0 and increment the number for each drive.
SNFS Configure StorNext FS Software on Solaris To configure the StorNext FS software on a Solaris machine, you have to configure the software on the StorNext FS server and StorNext FS clients. Server Configuration Step 1 Create a StorNext FS-managed file system by copying /usr/cvfs/examples/ example.cfg and renaming it. # cd/usr/cvfs/config # cp ../examples/example.cfg ./.cfg NOTE Step 2 The example.
SNFS For example: [DiskType ST318202FC] Sectors 35563520 SectorSize 512 The SectorSize should reflect the Sector Format Size of the disk drives, for example: 512, 4096, 8192, 16384. To obtain the number of sectors where the disks are set, use the cvlabel -1 command. If you are using disk devices that do not have the same number of sectors, then several disk types can be specified to handle each common number of sectors. DISK section - Identifies the disk drive that is labeled and available to StorNext FS.
SNFS STRIPEGROUP DEFINITION section - Describes a group of disks that comprise a stripe group. One or more stripe groups describe the entire file system. A stripe group is the smallest entity that can be manipulated by a system administrator using the File System Administration utility (cvadmin). NOTE All disks defined in any given stripe group must have the same number of sectors, as reported by cvlabel -1. Examples of stripe groups appear in the configuration file.
SNFS Step 5 Initialize StorNext FS. Enter: # cd /usr/cvfs/bin/cvmkfs # cp ../examples/fsmlist.example ./fsmlist CAUTION Step 6 This step cannot be undone and all data on the file system will be lost, so make sure you are ready to initialize the file system before you proceed. Create the fsmlist file. Enter: # cd /usr/cvfs/config # cp ../examples/fsmlist.example ./fsmlist Step 7 Edit /usr/cvfs/config/fsmlist so that it contains the names of all StorNext File Systems.
SNFS Mount StorNext FS on Solaris To mount StorNext FS: Step 1 Create the StorNext FS mount directory. For example: # mkdir /usr/clips Step 2 Add the uniquely named StorNext FS-managed file system to the /etc/vfstab file. Use cvfs as the file system type. /usr/clips cvfs - yes rw,threads=6 where: Option Description Uniquely named StorNext FS-managed file system.
