Backing Up System Configuration
Precautions for Cluster Environments
In a cluster environment, the software version command may temporarily suspend normal HA
communications, while internal checks are made to ensure that the new software can be run. A
suspension will cause a failover of any SCSI routing instances active on the storage router.
Any instances with the primary attribute set to the name of the SN 5428-2 will resume running on the
storage router after it is rebooted or after normal HA communications are restored.
If the storage router is running in a cluster environment, issuing the reboot command will attempt
failover for all SCSI routing instances to another storage router in the cluster. The iSCSI drivers handle
reconnection of users to the appropriate storage resources, minimizing the effects of the reboot sequence
on those users.
Backing Up System Configuration
Backing up the system configuration consists of saving selected storage router configuration information
to XML files that can be stored both locally and remotely. Should problems occur, AAA authentication
information, access lists, Fibre Channel (FC) interface and switch configuration, SCSI routing instances,
FCIP instances, VLANs and other storage router system configuration information can be restored from
these files. See Chapter 12, “Command Line Interface Reference,” for more information about what
configuration data is saved.
While you can issue a save command at any time during a CLI command session, best practices suggest
that you should back up the storage router system configuration to a file on a regular basis.
Configuration files are maintained in the savedconfig directory on the SN 5428-2. You can use the copy
command to copy the configuration file to a server running TFTP, allowing you to integrate the storage
router backups with other software archives.
By accessing the web-based GUI from a remote server, you can create storage router backup files
directly on that server. See the GUI online help for details.
Note See Chapter 12, “Command Line Interface Reference,” for more information about using the save and
copy commands.
Creating Local Backups
Local backups allow you to store the resulting XML configuration file in the savedconfig directory on
the SN 5428-2.
Use the following procedure to perform a local backup that saves the storage router system configuration
to a file named mybackup in the savedconfig directory.
Step 3
show software version boot Verify that the correct version is shown as the bootable version
(identified as Boot Version).
Step 4
reboot When you are ready to run the new software version, restart the
storage router.
