Test and restore firmware on Backbones
9
If an AP blade is present: At the point of the failover an autoleveling process is activated.
See “Backbone firmware download process overview” on page 198 for details about
autoleveling.
8. Verify the failover.
a. Connect to the Backbone on the active CP, which is the former standby CP.
b. Enter the haShow command to verify that the HA synchronization is complete. It takes 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 ensures 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 Backbone on the standby CP, which is the old active CP.
b. Enter the firmwareDownload command with the -s -b -n operands. This ensures that the
following steps are successful.
At this point the firmware downloads to the standby CP only and reboots it. The current
Backbone session is disconnected.
c. Wait one minute for the standby CP to reboot, and then connect to the Backbone 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.
ATTENTION
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 Backbone 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 not do anything on the Backbone while this operation is in process.
11. Perform a commit on the active CP.
a. From the current Backbone session on the active CP, enter the firmwareShow command
and confirm that only the active CP secondary partition contains the old firmware.
b. Enter the firmwareCommit command to update the secondary partition with the new
firmware. It takes several minutes to complete the commit operation. Do not do anything
on the Backbone while this operation is in process.
c. Upon completion of the firmwareCommit command, type the firmwareShow command to
confirm both partitions on both CPs contain the new firmware.
