Download D) Downloading Disk Array Firmware from a File on a V-Class system using
dfdutil Utility
Assumptions: Use this procedure when the desired version of controller firmware is available as a
DFDUTIL.LIF file for the V-Class system.
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! For information on dfdutil, refer to the man page dfdutil.
