ATTO Technology Inc. Diamond Storage Array Installation and Operation Manual
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
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]
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
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
