software. The remaining four characters will be entered by the system automatically to identify the tape number. See Virtual Tape on page 49 and Optional Hot Spare Sled on page 50 for more information and examples.

Note

The maximum number of tape volumes and tape drives for RAID Level 5 is 30.

The maximum number of tape volumes and tape drives for RAID Level 10 is 15.

Set syntax: set QuickTape [RAID5 RAID10] [# tape volumes] [# tape drives] <enabled> <barcode prefix>

Requires a SaveConfiguration command

Get syntax: get QuickTape

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. For

RAID Level 10, choices are 16, 32, 64, 128, 256 or SPAN. For RAID Level 5, choices are: 16, 32, 64, 128, 256.

Default: 128

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

RAIDHaltRebuild

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

Immediate command: RAIDHaltRebuild [Sled Number]

RAIDManualRebuild

Initiates a manual rebuild of a RAID Level 5 or 10 LUN. An error message is returned if the specified LUN is not a RAID 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]

RAIDRebuildState

Sets the RAID Level 5 or 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.

Get syntax: RAIDRebuildStatus

RAIDResumeRebuild

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

Immediate command: RAIDResumeRebuild [Sled Number]
