HP StorageWorks Fabric OS 6.x administrator guide (5697-7344, March 2008)

180 Installing and maintaining firmware
IMPORTANT: Stop! If you want to restore the firmware, stop here and skip ahead to step 9;
otherwise, continue to step 8 to commit the firmware on the switch, which completes the firmware
download operations.
8. Commit the firmware.
a. Enter the firmwareCommit command to update the secondary partition with new firmware. Note
that it takes several minutes to complete the commit operation.
b. Enter the firmwareShow command to confirm both partitions on the switch contain the new
firmware.
IMPORTANT: Stop! If you have completed step 8, then you have committed the firmware on the
switch and you have completed the firmware download procedure. To restore the original firmware,
refer to step 9 (should be performed after step 6).
9. Restore the firmware.
a. Enter the firmwareRestore command. The switch will reboot and come up with the original
firmware again.
A firmwareCommit will automatically begin to copy the original firmware from the primary
partition to the secondary partition. At the end of the firmware commit process, both partitions will
have the original firmware. Note that it takes several minutes to complete the commit operation.
b. Wait five minutes to ensure that all processes have completed and the switch is fully up and
operational.
c. Log in to the switch. Enter the firmwareShow command and verify that both partitions on the
switch have the original firmware.
Testing and restoring firmware on directors
This procedure enables you to perform a firmware download on each CP and verify that the procedure
was successful before committing to the new firmware. The old firmware is saved in the secondary partition
of each CP until you enter the firmwareCommit command. If you decide to back out of the installation
prior to the firmwareCommit, you can enter the firmwareRestore command to restore the former
active Fabric OS firmware image.
The firmwareRestore command can only run if autocommit was disabled during the
firmwareDownload.
NOTE: HP recommends that, under normal operating conditions, you maintain the same firmware version
on both CPs, and on both partitions of each CP. This procedure enables you to evaluate firmware before
you commit. As a standard practice, you should not run mixed firmware levels on CPs.
To test a different firmware version in a Director:
1. Connect to the HP logical switch IP address.
2. Enter the ipAddrShow command and note the address of CP0 and CP1.
3. Enter the haShow command and note which CP is active and which CP is standby. Verify that both CPs
are in sync.
CP blades must be synchronized and running Fabric OS 4.4.0 or later to provide a nondisruptive
download. If the two CP blades are not synchronized, enter the haSyncStart command to
synchronize them. If the CPs still are not synchronized, contact HP.
4. Enter the firmwareShow command and confirm that the current firmware on both partitions on both
CPs is listed as expected.
5. Exit the session.
