To Perform a Mirrored Disk Hot-Plug Operation

▼
1. Verify which hard drive corresponds with which logical device name and physical
device name.
See "Disk Slot Numbers, Logical Device Names, and Physical Device Names" on
page
2. To confirm a failed disk, type the following command:
# raidctl
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.
For example:
# raidctl
RAID
Volume
--------------------------------------------------------
c0t1d0
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 SPARC Enterprise T2000 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 SPARC Enterprise T2000 Server Service
Manual.
The RAID utility automatically restores the data to the disk.
