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
<array-id>
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
<codefilename>
(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 <array-id>
) or front panel
(Shutdown). The following table shows the proper front panel commands to shutdown the array:
KEY DISPLAY
CANCEL CANCEL
“Ready”
MENU “Language”
– “View
Settings”
– “Shutdown”
ENTER “Confirm”
ENTER “Shutting
Down”
then “Shutdown Complete”
5. Download the firmware (
download -C <codefilename> <array-id>
).
