Upgrading Array Controller Firmware

Upgrading Link Controller Card Firmware

1 Backup any data on the array that you wish to keep. You may also want to
record the LUN structure on the array. You will need to recreate it after
formatting the array.
2 Perform the steps in "Upgrading Array Controller DIMMs" on page
removing or replacing DIMMs as required. The cache must be reduced on
both controllers.. After powering on the array, continue with the following
steps.
3 Check the status of the array. It should indicate No Maps.
4 Format the array using CommandView SDM or the VFP.
5 Recreate the original LUN structure on the array.
6 Reload any backed up data.

Caution To prevent data loss, it is recommended that a full backup be
performed before starting this procedure.
Note When downloading controller firmware, always check the
README file included with the firmware. (If you have access,
you can also read the HP Service Note associated with the
firmware download.) This information will identify whether you
can perform the firmware download offline or online.
1 Download new firmware to an active array controller using
CommandView SDM. See "Upgrading Array Controller Firmware" in the
on-line Help.
The download process copies the new firmware to the other array controller
automatically.
Note When firmware microcode is fully downloaded, the array
controller suspends I/Os for about 10 seconds, then switches to
the new code.
