One of the RAID Controller’s battery on my Dell PowerVault MD3200 has failed today so I got a replacement part to replace it.
the battery requires detaching the RAID Controller from the MD3200.
However, there was no down time because the other RAID Controller is
still functioning. We just need to make sure all the disk groups have
been changed over to the working RAID Controller by using the PowerVault
Modular Disk Storage Manager in the Logical View.
Then in the Physical view, select the RAID Controller to be removed.
Click on the Advanced menu and select Recovery –> Place RAID
Controller Module –> Offline. This will place the RAID Controller
offline and we are ready to remove it.
This is how the RAID Controller with the battery removed looks like.

After replacing the the battery pack, reinsert the RAID Controller back
and place it online. Wait for a few minutes and everything is back to
