Replacing an internal disk of a RAID volume is simple but requires attention ensuring completion of each step.
Applies to:
Sun SPARC Enterprise T5120 Server - Version: Not Applicable to Not Applicable - Release: N/A to N/A
Sun SPARC Enterprise T5220 Server - Version: Not Applicable to Not Applicable [Release: N/A to N/A]
Information in this document applies to any platform.
Goal
To assist customers and technicians on replacing internal disks that are part of a RAID volume.
Solution
1. Once a volume failure has been identified, list its disks via 'raidctl' in order to identify the failed disk.
root@Server-T5120 # raidctl
Controller: 1
Volume:c1t0d0
Disk: 0.0.0
Disk: 0.1.0
Controller: 2
Controller: 3
root@Server-T5120 # raidctl -l c1t0d0
Volume Size Stripe Status Cache RAID
Sub Size Level
Disk
----------------------------------------------------------------
c1t0d0 136.6G N/A DEGRADED OFF RAID1
0.0.0 136.6G GOOD
N/A 136.6G FAILED
2. Locate the defective disk in the chassis following Server's specific documentation. Pay careful attention. Removing the incorrect disk may result in a total loss of the volume.
3. Remove the defective disk.
4. Make sure the removal has been acknowledged by Solaris checking '/var/adm/messages' for reports on the removal of the HD:

Notice both Solaris and ipmi/SC logs are printed.
5. Following that, insert the new disk. See the volume resync started:
6. Follow the resync process until confirmed its completion:
root@Server-T5120 # raidctl -l c1t0d0
