Fabric OS 6.1.1 administrator guide 191
IMPORTANT: If the CPs do not achieve synchronization, stop here. Log in to the standby CP, and issue the
firmwareRestore command to restore the original firmware.
c. Issue the firmwareShow command to confirm that the primary partition of the standby CP
contains the new firmware.
d. Issue the haFailover command. The active CP reboots and the current switch session is
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 182 for details
about autoleveling.
8. Verify the failover:
a. Connect to the enterprise-class on the active CP, which is the former standby CP.
b. Issue 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 will ensure that the standby CP is updated to
the same version as the active CP.
c. Confirm that the evaluation version of firmware is now running on the active CP by issuing the
firmwareShow command.
9. Update firmware on the standby CP:
a. Connect to the enterprise-class on the standby CP, which is the old active CP.
b. Issue 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 enterprise-class and log in as
admin.
d. Issue 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, issue 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 enterprise-class while this operation is in process.
11. Perform a commit on the active CP:
a. From the current switch session on the active CP, issue the firmwareShow command and confirm
that only the active CP secondary partition contains the old firmware.
b. Issue 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 switch while this
operation is in process.
c. Upon completion of the firmwareCommit command, issue the firmwareShow command to
confirm that both partitions on both CPs contain the new firmware.
d. Issue the haShow command to confirm that the HA state is in sync.
