IMPORTANT: Stop! If you have completed step 8, you have committed the firmware on the switch and you have completed the firmware download procedure. To restore the original firmware, see step 9 (should be performed after step 6). 9. Restore the firmware. a. Issue the firmwareRestore command. The switch reboots and comes up with the original firmware again. A firmwareCommit automatically begins 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. d. Issue the firmwareShow command and verify that both partitions on the switch have the original firmware. Testing and restoring firmware on directors 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 issue the firmwareCommit command. If you decide to back out of the installation prior to the firmwareCommit, you can issue the firmwareRestore command to restore the former active Fabric OS firmware image. The firmwareRestore command can run only if autocommit was disabled during the firmware download. NOTE: HP 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. To test a different firmware version in a Director: 1. Connect to the HP logical switch IP address. 2. Issue the ipAddrShow command and note the address of CP0 and CP1. 3. Issue the haShow command and note which CP is active and which is standby. Verify that both CPs are in sync. CP blades must be synchronized and running Fabric OS 6.0.0 or later to provide a nondisruptive download. If the two CP blades are not synchronized, issue the haSyncStart command to synchronize them. If the CPs still are not synchronized, contact HP. 4. Issue the firmwareShow command and confirm that the current firmware on both partitions on both CPs is listed as expected. 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. Issue 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 switch session will be disconnected. 7. Fail over to the standby CP. a. Connect to the enterprise-class on the active CP. b. Issue 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. 190 Installing and maintaining firmware
