F.8 Identifying the Faulty Disk Drive of a Hardware RAID Volume


F.8 Identifying the Faulty Disk Drive of a Hardware RAID Volume
Use the sas2ircu display command to identify the faulty hardware RAID volume and the faulty disk drive.
In the following example, the disk drive of disk slot 1 of the SPARC M10-1 is faulty.
In the examples that follow, (1) to (2) indicate the following:
(1): RAID volume information

(1-1): RAID volume 2 information
You can obtain the following information (partial extract).
- RAID volume ID is 286

- RAID volume status is Degraded (Degraded (DGD))

- RAID level is RAID1 (Mirroring)

- Disk (2:0) of SPARC M12/M10 internal disk slot 0 is mounted in PHY[0] (Primary)

- PHY[1] (Secondary) has no disk information (0:0)

(2): Physical device information

(2-1): Status of disk drive (Drive Type=SAS_HDD) that has no information on installation location (Enclosure#:0,Slot#:0 = previously existed as Enclosure#:2,Slot#:1 but was not accessible when this command was executed)

This indicates that the disk drive is out of order. (State:Failed (FLD))

Note - The following message may be displayed on Oracle Solaris after operating a RAID volume to create or delete a RAID volume, delete a hot spare, etc. This indicates that there is no label information on the RAID volume or the disk drive. The RAID volume or the disk drive in this state cannot be used on Oracle Solaris. It will be usable on Oracle Solaris after executing the format command, selecting the appropriate RAID volume or disk drive, and labeling it.
