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.
