Controller HP SureStore E Disk Array 12H Controller Firmware Download Procedure Replace D) Replacing an Array Controller in an Array with one controller installed. Assumption #1: If a successful shutdown has occurred in which the NVRAM memory maps were copied to the disk drive modules, then you can replace the controller and restore the maps using the following procedure: 1. If replacement controller is new, install the controller batteries (supplied). 2. If replacement controller is NOT new, reset (disconnect and then re-connect) both batteries on the replacement controller at the same time to erase NVRAM. 3. Replace the failed controller with the new one in controller slot X. 4. Push the on/off button to the on position and wait for the initialization to complete. 5. The disk array should display the "Ready" state. Check the system state. There should be no other warnings. KEY CANCEL CANCEL MENU - ENTER + DISPLAY "Ready" "Language" "View Settings" "System State: Ready" "Primary Cntrl: X" Assumption #2: Since there is only one controller in the array, it is very likely that when the controller failed the NVRAM memory maps were destroyed as well. If the maps were destroyed or the procedure failed above, there are only two other options: 1. Try to restore maps using arrayrecover command. See the man page for details on command usage. NOTE! The arrayrecover utility is only available on ARMServer patch released IPR 9810 or newer (PHCO_15699 for 10.x and PHCO_15700 for 11.0 or newer). Also, the array controller firmware must be running version HP4x or newer. 2. Restore array configuration (LUN and or LVM) plus data from backup storage medium. 67
