Fabric OS 5.3.0 administrator guide 187
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.
CAUTION: Stop! If you want to restore the firmware, stop here and skip ahead to step 10; otherwise,
continue to step 11 to commit the firmware on the switch, which completes the firmware download
operations.
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.
11. Perform a commit on the active CP.
a. From the current switch 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 switch 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.
d. Enter the haShow command to confirm that the HA state is in sync.
CAUTION: Stop! If you have completed step 11, then you have committed the firmware on both CPs and
you have completed the firmware download procedure. The following step 12 through step 14 describe
how to restore the original firmware, and should be performed after step 5.
12. Restore the firmware on the standby CP.
In the current switch session for the standby CP, enter the firmwareRestore command. The standby
CP will reboot and the current switch session will end. Both partitions will have the same Fabric OS
after several minutes.
13. Perform haFailover on the active CP.
a. In the current switch session for the active CP, 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.
b. Enter the haFailover command. The active CP will reboot and the current switch session will end.
The switch is now running the original firmware.
14. Restore firmware on the “new” standby CP.
a. Wait one minute and connect to the switch on the new standby CP, which is the old active CP.
