physical device name.

2. To confirm a failed disk, type the following command:
If the Disk Status is FAILED, then the drive can be removed and a new drive
inserted. Upon insertion, the new disk should be OK and the volume should be
RESYNCING.

Note –

depending on the number and type of add-on disk controllers installed.

.
There is no need to issue a software command to bring the drive offline when the
drive has failed.
4. Install a new hard drive, as described in your server’s service manual.
The RAID utility automatically restores the data to the disk.
