Controller HP SureStore E Disk Array 12H Controller Firmware Download Procedure Download C) Downloading Disk Array Firmware from a File Using Off-Line Diagnostics (ARDIAG) Assumptions: Use this procedure if the desired version of firmware is available on a tape or other such media that can boot with the offline diagnostic environment (ODE). Do not use this procedure if the system is on a V class computer. CAUTION! Controller firmware HP4x and any later versions have a different data map format in NVRAM memory. Once you have HP4x 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. NOTE!
