▼ To Perform a Mirrored Disk Hot-Swap
Operation
1. Verify which hard drive corresponds with which logical device name and physical
device name.
See “Slot Numbers and Device Names for Non-RAID Disks” on page 67.
If the Disk Status is FAILED, then the drive can be removed and a new drive
inserted. Upon insertion, the new disk status should be OK and the volume should
be RESYNCING.
2. To confirm a failed disk, type the following command:
For example:
This example indicates that the disk mirror has degraded due to a failure in disk
c0t2d0.
Note – The logical device names might appear differently on your system,
depending on the number and type of add-on disk controllers installed.
3. Remove the hard drive, as described in the server service manual.
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 the server service manual.
The RAID utility automatically restores the data to the disk.
