14.2.8 Checking the Status of a Hardware RAID Volume and a Disk Drive


14.2.8 Checking the Status of a Hardware RAID Volume and a Disk Drive
This section describes how to check the status of a hardware RAID volume and an internal disk drive within the hardware RAID volume.
To check the status of a hardware RAID volume and a disk drive within the hardware RAID volume, use the Fcode utility or the SAS2IRCU utility with the following commands.
Table 14-10  Status Display Commands of Hardware RAID
Utility Name Command Name
FCode utility show-volumes command
SAS2IRCU utility STATUS command
DISPLAY command
The following describes the main status and the description when each utility command is executed.

RAID level RAID0 (Striping) RAID0 RAID0 (Striping) volume
  RAID1 (Mirroring) RAID1 RAID1 (Mirroring) volume
  RAID10 (Striped Mirroring) RAID10 RAID10 (Mirroring + Striping) volume
  RAID1E (Mirroring Extended) RAID1E RAID1E (Mirroring Extended) volume
Hardware RAID volume status (typical example) Optimal Optimal Hardware RAID volume operating normally
  Degraded Degraded Hardware RAID volume degraded
  Missing Missing Hardware RAID volume not found
  Failed Failed Hardware RAID volume failed
  Enabled Enabled Hardware RAID volume active
  Inactive Inactive Hardware RAID volume inactive
  Data Scrub In Progress None Data scrub status of a hardware RAID volume
This indication is not a problem because the hardware RAID firmware performs automatically.
  Background Init In Progress Background Init Hardware RAID volume configuration in process
The hardware RAID volume is not fully configured.
  Resync In Progress Synchronize Resynchronization of a RAID volume is in process.
The hardware RAID volume is not fully configured.
  Consistency Check In Progress Consistency Check Hardware RAID volume consistency being checked
Disk drive status (typical example) Optimal Optimal (OPT) Target disk drive incorporated into a hardware RAID volume
  Offline Failed (FLD) Target disk drive not incorporated into a hardware RAID volume
  Degraded Degraded (DGD) Target disk drive degraded
  Rebuilding Rebuilding (RBLD) Target disk drive being incorporated into a hardware RAID volume
  Out Of Sync Out of Sync (OSY) Target disk drive out of synchronization with hardware RAID volume
Displaying the Status With the FCode Utility
To check the status of a hardware RAID volume and an internal disk drive within the hardware RAID volume, stop the system and execute the show-volumes command with the FCode utility.
  1. Confirm that the ok prompt is displayed.
  2. Execute the select command with the controller name to display its hardware RAID volumes.
Note - After executing the select command, you need to execute the unselect-dev command. After the procedure is finished, execute the unselect-dev command according to the instruction in step 4.
{0} ok select /pci@8000/pci@4/pci@0/pci@0/scsi@0
{0} ok
  1. Execute the show-volumes command to check RAID volumes.
    The following example shows the following:
    (1) The RAID type of the hardware RAID volume is "RAID1 (Mirroring)."

    (2) The hardware RAID volume is "Degraded" and "Enabled."

    (3) Of the disk drives that make up the hardware RAID volume, Disk 0 is "incorporated as Primary (Optimal)."

    (4) Of the disk drives that make up the hardware RAID volume, Disk 1 is "not incorporated as the Secondary (Offline)" and is "out of synchronization (Out Of Sync)."
{0} ok show-volumes
Volume 0 Target 11e Type RAID1 (Mirroring) <-- (1)
Name raid1-volume WWID 0c233a838262c6c5
Degraded Enabled <-- (2)
2 Members 1169920000 Blocks, 598 GB
Disk 0
Primary Optimal <-- (3)
Target a TOSHIBA MBF2600RC 3706 PhyNum 0
Disk 1
Secondary Offline Out Of Sync <-- (4)
Target b TOSHIBA MBF2600RC 3706 PhyNum 1
{0} ok
Note - The error status of the disk drive itself can be displayed after it is released from the hardware RAID.
  1. Use the unselect-dev command to unselect the controller that was selected during preparation.
{0} ok unselect-dev
{0} ok
Displaying the Status With the SAS2IRCU Utility
You can also use the SAS2IRCU utility to check the status of a hardware RAID volume and an internal disk drive within the hardware RAID volume.
For details on the SAS2IRCU utility, see the beginning of "14.2 Configuring Hardware RAID."
