RAID5ClearData

To Zero all drives and parity to make newly created RAID5 groups ‘coherent’. The parameter ALL clears data on all RAID5 groups present in the system. Must be used at initial configuration to ensure parity is valid for all drives in the RAID Level 5 group by setting all data and parity to zero. Takes all LUNs offline automatically, then brings them online. The operation takes 3-6 hours, depending on drive capacity. Do not interrupt this process. This is a destructive operation: all information on these drives is lost. Applies to RAID5 only

Set syntax: RAID5ClearData [ALL LUN]

Get syntax: DriveCopyStatus or RAID5ClearDataStatus

RAID5ClearDataStatus

Displays the status of RAID5 Clear Data processing. S represents the sled number, D represents the drive number. Applies to RAID5 only

Set syntax: RAID5ClearDataStatus

RAIDInterleave

Specifies the Interleave size (in 512 byte blocks) between members of a RAID group. SPAN indicates that the interleave size between drives in the group is the minimum drive size of all members in the group. RAIDInterleave options are 16, 32, 64, 128, 256 blocks and span. Span is not available for RAID Level 5.

Choices all but RAID Level 5: 16, 32, 64, 128, 256 or

SPAN

Choices RAID 5: 16, 32, 64, 128, 256

Default: 128

Set syntax: set RAIDInterleave [1-256] [SPAN] Requires a SaveConfiguration Restart command Get syntax: get RAIDInterleave

RAIDRebuildState

Sets the RAID Level 1, Level 5 or Level 10 rebuild status of the specified sled to OK, degraded or faulted.

Set syntax: set RAIDRebuildState [Sled Number] [Degraded OK Faulted]

RAIDRebuildStatus

Displays the RAID1, RAID 5 or RAID 10 Rebuild Status Summary. If no RAID groups are defined, the header information is displayed with no data. The status summary contains the RAID1, RAID 5 or RAID 10. The RAIDRebuildStatus command has no effect on the state of any rebuild in progress.

Member index and the following fields in tabular form: Status, Sled Number, Current LBA, Maximum LBA, Status.

RAIDResumeRebuild

Resumes a RAID Level 1, Level 5 or Level 10 rebuild which had been previously stopped.

Immediate command: RAIDResumeRebuild [Sled Number]

RebuildPriority

Sets the priority of a RAID Level 1, Level 5 or Level 10 rebuild. If you select High priority, rebuild I/O requests are implemented before system I/O requests. I f you select Low priority, rebuild I/O requests executes only when there are no pending I/O requests. If you select Same priority, rebuild I/O and system I/O receive equal consideration.

Set syntax: set RebuildPriority [high low same] Requires a SaveConfiguration Restart command Get syntax: get RebuildPriority

RAIDHaltRebuild

Stops a RAID Level 1, 5 or 10 rebuild that is in progress.

Immediate command: RAIDHaltRebuild [Sled Number]

RAIDManualRebuild

Initiates a manual rebuild of a RAID Level 1, 5 or 10 LUN. An error message is returned if the specified LUN is not a RAID Level 1, Level 5 or 10 LUN or if the sled number is not available; no rebuild takes place. Applies to RAID Levels 1, 5 and 10 only

Set syntax: RAIDManualRebuild [LUN] [Sled Number]

ResolveLUNConflicts

Re-numbers any conflicting Logical Unit numbers that exist in the Diamond. Conflicts may occur when a unit is taken from one Array and inserted into another Array.

Set syntax: ResolveLUNConflicts

RestoreModePages

Restores all mode pages to the factory set default. Restarting the Diamond Storage Array is required for settings to take effect.

Set syntax: RestoreModePages
