Goal
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.
Fix
Steps to Follow
Hardware Disk Layout:
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
How to Replace a Failed Disk Mirrored with the raidctl Command;
1.To confirm a failed disk, type the following command:
# 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.
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
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
raidctl, mirror, failed, replace, SFV440
