9 Test and restore firmware on enterprise-class platforms ATTENTION Stop! If you want to restore the firmware, stop here and skip ahead to step 9; otherwise, continue to step 8 to commit the firmware on the switch, which completes the firmware download operations. 8. Commit the firmware. a. Enter the firmwareCommit command to update the secondary partition with new firmware. Note that it takes several minutes to complete the commit operation. b. Enter the firmwareShow command to confirm both partitions on the switch contain the new firmware. ATTENTION Stop! If you have completed step 8, then you have committed the firmware on the switch and you have completed the firmware download procedure. 9. Restore the firmware. a. Enter the firmwareRestore command. The switch will reboot and come up with the original firmware again. A firmwareCommit will automatically begin to copy the original firmware from the primary partition to the secondary partition. At the end of the firmware commit process, both partitions will have the original firmware. Note that it takes several minutes to complete the commit operation. b. Wait five minutes to ensure that all processes have completed and the switch is fully up and operational. c. Log in to the switch. Enter the firmwareShow command and verify that both partitions on the switch have the original firmware. Test and restore firmware on enterprise-class platforms This procedure enables you to perform a firmware download on each CP and verify that the procedure was successful before committing to the new firmware. The old firmware is saved in the secondary partition of each CP until you enter the firmwareCommit command. If you decide to back out of the installation prior to the firmwareCommit, you can enter the firmwareRestore command to restore the former active Fabric OS firmware image. The firmwareRestore command can only run if autocommit was disabled during the firmwareDownload. This command cannot be used to restore SAS and SA images. NOTE Brocade recommends that, under normal operating conditions, you maintain the same firmware version on both CPs, and on both partitions of each CP. This procedure enables you to evaluate firmware before you commit. As a standard practice, you should not run mixed firmware levels on CPs. 204 Fabric OS Administrator's Guide 53-1001763-01
