1. Verify which hard drive corresponds with which logical device name and
physical device name.
See "Disk Slot Numbers" on page
2. To confirm a failed disk, type:
# 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

c0t2d0.

There is no need to issue a software command to bring the drive offline when the
drive has failed.
