Setting Updated Software as Boot Version
Downloading updated software to the storage router does not change the currently
running version of the software, nor does it automatically set the new version to be
booted at next system restart. You must take specific action to make the new
software version bootable.
Setting software as the bootable version consists of verifying the software
integrity and performing internal checks to ensure that the storage router can boot
the specified version of software.
To set the new software as the version to be booted:
1. enable — Enter Administrator mode.
2. software version 3.1.3 — Select the software to be booted when the
system next starts (for example, boot 3.1.3 when the system restarts). The
system checks the integrity of the specified software version to be sure that it
is bootable.
3. show software version boot — Verify that the correct version is
shown as the bootable version (identified as Boot Version).
4. reboot — Restart the storage router to run the new software. (Optional)
When you set a new software version as the bootable version, internal checks are
made to ensure that the new software can be run.
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 storage router will
resume running on the storage router after it is rebooted. If you are not going to
reboot the storage router immediately, use the failover scsirouter
command to return the desired SCSI routing instances to the storage router.
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.
