Automatic Replacement Recognition (ARR) for drives

When a drive is replaced in a node, OneFS automatically formats and adds the drive to the cluster.

If you are replacing a drive in a node, either to upgrade the drive or to replace a failed drive, you do not need to take additional actions to add the drive to the cluster. OneFS will automatically format the drive and add it.

ARR will also automatically update the firmware on the new drive to match the current drive support package installed on the cluster. Drive firmware will not be updated for the entire cluster, only for the new drive.

If you prefer to format and add drives manually, you can disable ARR.
