F.2 Displaying the Information of a Hardware RAID Volume


F.2 Displaying the Information of a Hardware RAID Volume
Use the sas2ircu display command to display the information of hardware RAID volumes and disk drives configured in the system.
The following example shows the RAID 1 (Mirror) volume which is equipped with a disk drive in disk slot 0 as Primary and a disk drive in disk slot 1 as Secondary, and disk drives which do not make up the hardware RAID, in disk slots 2, 3, 4, and 5 for the SAS controller (*1) with Index=1.
*1 This can be checked by the sas2ircu list command. See "F.1 Displaying a List of SAS Controllers Recognized by sas2ircu."
In the examples that follow, (1) to (4) indicate the following:
(1): SAS controller information

(2): RAID volume information

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

- RAID volume name is RAID1-SYS

- RAID volume status is normal (Okay (OKY))

- RAID level is RAID1 (Mirroring)

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

- Disk (2:1) of SPARC M12/M10 internal disk slot 1 is mounted in PHY[1] (Secondary)

(3): Physical device information

(3-1): Status of a disk drive (Drive Type=SAS_HDD) of SPARC M12/M10 internal disk slot 0 (Enclosure#:2,Slot#:0)

It is optimized as a part of the RAID volumes. (State:Optimal (OPT))

(3-2): Status of an enclosure services device (Device Type= Enclosure services device) of SPARC M12/M10 internal disk slot 0 (Enclosure#:2,Slot#:0)

This represents a device other than hard disks. Although the Standby state is shown, this is a normal display. (State:Standby (SBY))

(3-3): Status of a disk drive (Drive Type=SAS_HDD) of SPARC M12/M10 internal disk slot 2 (Enclosure#:2,Slot#:2)

   This represents a disk drive that is not in the RAID configuration. The status indicates that it can be incorporated into a RAID volume and a hot spare. (State:Ready (RDY))

(4): SPARC M12/M10 chassis information

(4-1): SAS address of the SAS controller
Note - You can find the device path and installation location of the SAS controller by checking the SAS address of the SAS controller on OpenBoot PROM beforehand and comparing it with what is displayed by the sas2ircu display command. For details on how to obtain SAS controller information on OpenBoot PROM, see "14.2.4 Preparation Before Hardware RAID Operation."
