To Perform a Mirrored Disk Hot-Plug Operation
Caution – Ensure that the disk drive OK-to-Remove indicator is lit, indicating that
the disk drive is offline. If the disk drive is still online, you risk removing the disk
during a read/write operation, which could result in data loss.
1. To confirm a failed disk, type the following command:
# raidctl
For example:
# raidctl
RAID RAID RAID Disk
Volume Status Disk Status
----------------------------------------
c1t1d0 DEGRADED c1t1d0 OK
c1t2d0 DEGRADED
This example indicates that the disk mirror has degraded due to a failure in disk
c1t2d0.
Note – The logical device names might appear differently on your system,
depending on the number and type of add-on disk controllers installed.
2. Remove the disk drive, as described in the Sun Fire V445 Server Service Manual.
There is no need to issue a software command to bring the drive offline when the
drive has failed and the OK-to-Remove indicator is lit.
3. Install a new disk drive, as described in the Sun Fire V445 Server Service Manual.
The RAID utility automatically restores the data to the disk.
