1 1. 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.
IMPORTANT:
CPs and you have completed the firmware download procedure. The following
step 14 describe how to restore the original firmware, and should be performed after
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.
b. 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.
c. Wait five minutes and log in to the switch. Enter the firmwareShow command and verify that all
partitions have the original firmware.
If an AP blade is present: Blade partitions always contain the same version of the firmware on
both partitions (it does not keep two copies). The firmware is stored on the blade's compact flash
card and is always synchronized with the active CP's firmware. Thus, if you restore the active CP
firmware, the blade firmware is automatically downloaded (auto-leveled) to become consistent with
the new CP firmware (the blade firmware is basically restored).
Your system is now restored to the original partitions on both CPs. Make sure that servers using the
fabric can access their storage devices.
If you want to upgrade a Director with only one CP in it, follow the procedures in
firmware on switches" on page 179. Note, however, that upgrading a Director with only one CP will be
disruptive to switch traffic.
