Controller HP SureStore E Disk Array 12H Controller Firmware Download Procedure Download A) Downloading Disk Array Firmware from a File Using ARMServer (AutoRAID Manager) CAUTION! Controller firmware HP4x and any later versions have a different data map format in NVRAM memory. Once you have HP48 or later, you can not "downgrade" to any firmware version prior to HP4x without first completely backing up all data on the array, including any meta-data, e.g., LUN and LVM configuration. After you have "downgraded" the firmware and formatted the array, all meta-data and real data will need to be restored from backup. Assumptions: Use this procedure if the desired version of firmware is available from the host system, and you want to update the firmware on the installed array controllers. 1. Get using ARMServer (arraydsp -i) or front panel (View Settings, Array S/N). You may also use the raw device file that is connected to the array. 2. Obtain the desired version of firmware and determine its (filename) and location (path). 3. Quiet (quiesce) or stop all I/Os, deactivate volume set, unmount file systems, stop traffic to the array. 4. Shutdown the array using ARMServer (arraymgr -s shut ) or front panel (Shutdown). The following table shows the proper front panel commands to shutdown the array: KEY CANCEL CANCEL MENU - - ENTER ENTER DISPLAY "Ready" "Language" "View Settings" "Shutdown" "Confirm" "Shutting Down" then "Shutdown Complete" 5. Download the firmware (download -C ). 44
