Replace A) Replacing an Array Controller (Version of Firmware on the Replacement Array Controller Matches Version of Firmware on the Installed Array Controllers) Assumptions: Use this procedure if an existing array controller has failed (if disk array is either a boot or non-boot device), and the replacement array controller has the same version of firmware as the installed array controllers. 1. If replacement controller is new, install the controller batteries (supplied). 2. If replacement controller is NOT new, reset (disconnect and then re-connect) both batteries on the replacement controller at the same time to erase NVRAM. 3. Verify which controller has failed by examining the logs using the logprint command. This is to make sure you do not remove the functioning (good) controller. 4. Remove the "failed" controller. After Initialization, display panel shows "Ready." 5. Install the replacement controller in the disk array. After initialization, display panel shows "Ready." 6. The disk array will display the "Ready" state when both versions of firmware match. 26

Replace A) Replacing an Array Controller (Version of Firmware on the Replacement Array
Controller Matches Version of Firmware on the Installed Array Controllers)
Assumptions:
Use this procedure if an existing array controller has failed (if disk array is either a boot or
non-boot device), and the replacement array controller has the same version of firmware as the installed
array controllers.
1.
If replacement controller is new, install the controller batteries (supplied).
2.
If replacement controller is NOT new, reset (disconnect and then re-connect) both batteries on the
replacement controller at the same time to erase NVRAM.
3.
Verify which controller has failed by examining the logs using the
logprint
command. This is to
make sure you do not remove the functioning (good) controller.
4.
Remove the “failed” controller. After Initialization, display panel shows “Ready.”
5.
Install the replacement controller in the disk array. After initialization, display panel shows “Ready.”
6.
The disk array will display the “Ready” state when both versions of firmware match.
