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.
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.
Item | Output Value | Description | |
---|---|---|---|
FCode Utility show-volume Command |
SAS2IRCU Utility STATUS Command DISPLAY Command |
||
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.
- Confirm that the ok prompt is displayed.
- 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 |
- 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. |
- 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."
