230 Installing and maintaining firmware
10. Perform a commit on the standby CP.
From the current enterprise-class platform 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 enterprise-class platform while this operation is in
process.
11. Perform a commit on the active CP:
a. From the current enterprise-class platform 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 enterprise-class
platform while this operation is in process.
c. Upon completion of the
firmwareCommit
command, enter 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: Stop! If you have completed step 11 , you have committed the firmware on both CPs
and you have completed the firmware download procedure.
12. Restore the firmware on the standby CP.
In the current enterprise-class platform session for the standby CP, enter the
firmwareRestore
command. The standby CP will reboot and the current enterprise-class platform 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 enterprise-class platform 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 enterprise-class
platform session will end. The enterprise-class platform is now running the original firmware.
14. Restore firmware on the new standby CP.
a. Wait one minute and connect to the enterprise-class platform on the new standby CP, which is the
old active CP.
b. Enter the
firmwareRestore
command. The standby CP will reboot and the current
enterprise-class platform session will end. Both partitions will have the same Fabric OS after several
minutes.
c. Wait five minutes and log in to the enterprise-class platform. 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 an enterprise-class platform with only one CP in it, follow the procedures in ”
Test
and restore firmware on switches ” on page 227. Note, however, that upgrading an enterprise-class
platform with only one CP will be disruptive to switch traffic.
