6. Update the firmware on the standby CP:
a. Connect to the switch and log in as admin to the standby CP.
b. Enter the firmwareDownload -s command and respond to the prompts.
At this point, the firmware should download to the standby CP only. When it has completed the
download to that CP, reboot it. The current switch session will be disconnected.
7. Fail over to the standby CP.
a. Connect to the switch on the active CP.
b. Enter the haShow command to verify that HA synchronization is complete. It will take a minute or
two for the standby CP to reboot and synchronize with the active CP.
IMPORTANT: If the CPs do not achieve synchronization, stop here; log in to the standby CP, and enter the
firmwareRestore command to restore the original firmware.
c. Enter the firmwareShow command to confirm that the primary partition of the standby CP
contains the new firmware.
d. Enter the haFailover command. The active CP will reboot and the current switch session will be
disconnected.
If an AP blade is present: At the point of the failover an autoleveling process is activated. See,
”4/256 SAN Director and DC Director firmwareDownload procedure” on page 172 for details
about autoleveling.
8. Verify the failover:
a. Connect to the switch on the active CP, which is the former standby CP.
b. Enter the haShow command to verify that the HA synchronization is complete. It will take a minute
or two for the standby CP, which is the old active CP, to reboot and synchronize with the active CP.
NOTE: If the CPs fail to synchronize, you can still proceed because the version being tested is
already present on the active CP, and subsequent steps will ensure that the standby CP is updated to
the same version as the active CP.
c. Confirm the evaluation version of firmware is now running on the active CP by entering the
firmwareShow command.
9. Update firmware on the standby CP:
a. Connect to the switch on the standby CP, which is the old active CP.
b. Enter the firmwareDownload -s command and respond to the prompts.
At this point the firmware should download to the standby CP only and reboot it. The current switch
session will be disconnected.
c. Wait one minute for the standby CP to reboot, and then connect to the switch and log in as admin.
d. Enter the firmwareShow command to confirm that both primary partitions now have the test drive
firmware in place.
You are now ready to evaluate the new version of firmware.
IMPORTANT: Stop! If you want to restore the firmware, stop here and skip ahead to step 12;
otherwise, continue to step 10 to commit the firmware on both CPs, which completes the firmware
download.
10. Perform a commit on the standby CP.
From the current switch session on the standby CP, enter the firmwareCommit command to update
the secondary partition with new firmware. It takes several minutes to complete the commit operation.
Do no do anything on the switch while this operation is in process.
