5. Exit the session. 6. Update the firmware on the standby CP: a. Connect to the enterprise-class platform and log in as admin to the standby CP. b. Enter the firmwareDownload -s command and respond to the prompts. At this point, the firmware should download to the standby CP only. When it has completed the download to that CP, reboot it. The current enterprise-class platform session will be disconnected. 7. Fail over to the standby CP. a. Connect to the enterprise-class platform on the active CP. b. 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. CAUTION: If you are downgrading from Fabric OS 6.2.0 to 6.1.0, your CPs will not gain synchronization and this will be a disruptive firmware download. See Table 56 on page 215 for more information on synchronization states. c. Enter the firmwareShow command to confirm that the primary partition of the standby CP contains the new firmware. d. Enter the haFailover command. The active CP will reboot and the current enterprise-class platform session will be disconnected. If an AP blade is present: At the point of the failover an autoleveling process is activated. See, "Enterprise-class platform firmware download process overview" on page 220 for details about autoleveling. 8. Verify the failover: a. Connect to the enterprise-class platform on the active CP, which is the former standby CP. b. Enter the haShow command to verify that the HA synchronization is complete. It will take 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 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 enterprise-class platform 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 enterprise-class platform session will be disconnected. c. Wait one minute for the standby CP to reboot, and then connect to the enterprise-class platform 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. 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.
