Description
This document describes the process of replacing a failed disk with the
raidctl command in the mirroring configuration on the Sun Fire[TM] V440 server.

Steps to Follow
How to Replace a Failed Disk Mirrored with the raidctl Command;

Disk Slot Number	Logical Device Name[1]	         Physical Device Name
Slot 0			c1t0d0				/devices/pci@1f,700000/scsi@2/sd@0,0
Slot 1			c1t1d0				/devices/pci@1f,700000/scsi@2/sd@1,0
Slot 2			c1t2d0				/devices/pci@1f,700000/scsi@2/sd@2,0
Slot 3			c1t3d0				/devices/pci@1f,700000/scsi@2/sd@3,0
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. Install a new disk drive.
The RAID utility automatically restores the data to the disk.
3. To check the status of a RAID rebuild, type the following command:
# raidctl
For example:
# raidctl
RAID      RAID		        RAID      Disk
Volume    Status	        Disk      Status
--------------------------------------------------
c1t1d0	   RESYNCING		c1t1d0      OK
			        c1t2d0      OK
This example indicates that RAID volume c1t1d0 is resynchronizing.
If you issue the command again some minutes later, it indicates that the
RAID mirror is finished resynchronizing and is back online:
# raidctl
RAID      RAID		        RAID      Disk
Volume    Status	        Disk      Status
-------------------------------------------------
c1t1d0	   OK		        c1t1d0    OK
			        c1t2d0    OK
