• P artitionWriteCache
Enables higher write performance with a small risk of data loss
after a system failure. If disabled, provides a higher level of data
integrity with lower write performance.
s et PartitionWriteCache [GroupName] [PartIdx]
[enabled | disabled]
get PartitionWriteCache [GroupName] [PartIdx]
• R AIDRebuildPriority
S ets or displays the RAID rebuild priority. A RAID rebuild
priority set to high gives higher priority to RAID rebuilds and
lower priority to the processing of simultaneous read/write
transactions. A RAID rebuild priority set to low gives lower
priority to the rebuild and a higher priority to read/write
transactions. Set to same, the RAID rebuild and processing
of read/write transactions is the same. If all or no groups are
specified, the system default and all of the individual RAID
groups are set. If a group name is specified, only the specified
group is set.
set RAIDRebuildPriority <GroupName | all> [high
| low | same]
get RAIDRebuildPriority <GroupName | all>
• R AIDSpeedWriteLimit (Disabled on Error)
Sets or displays the limit on the coalescing factor. Warning:
changing the default setting (8) may result in poor performance
or timeouts. A lower setting is recommended when using
multiple initiators. A higher setting may improve performance
with multiple streams of sequential write I/O, but too high a
setting will cause timeouts.
set RAIDSpeedWriteLimit [0 - 32]
get RAIDSpeedWriteLimit
• R ebuildContinueOnError
Enables a rebuild to continue to completion even if media read
errors are encountered during the rebuild operation.
set RebuildContinueOnError [GroupName1 | all]
[enabled | disabled]
get RebuildContinueOnError [GroupName1 | all]
• R eserve (Immediate)
Reports the state of CLI reservation for the current CLI session.
If the command reports that reservations are enabled, then
another CLI session has control of parameter modification.
Reserve
• R estoreConfiguration (Immediate, Disabled on Error)
Forces the NVRAM settings to their original defaults when
issued with the default option. The saved option undoes any
changes made to this session since the last save.
RestoreConfiguration [default | saved]
• R GAddStorage (Immediate)
Adds additional storage to an existing RAID group. GroupName
is an ASCII name for the RAID group. MIRROR | STRIPE | SPAN
specifies the method used to expand the storage. Optional
parameter list BlockDeviceID specifies up to 10 indices of
available block devices, provided by the BlockDevScan CLI
command, to be added to the RAID group. If this list is
omitted, the CLI command RGMemberAdd must be used.
Optional parameter commit runs the RGCommit command
automatically and all user data will be erased from each new
member drive. If the parameter is omitted, the CLI command
RGCommit must be entered. Any time before RGCommit is
entered, the command RGCancelAddStorage can be used to
cancel the process. Note: Mirrors cannot be added to a RAID 4,
RAID 5, RAID 6, or DVRAID RAID group.
RGAddStorage [GroupName] [mirror | stripe |
span] <BlockDeviceID | <commit>
• R GAutoRebuild
Enables and disables Auto-Rebuild functionality for one or more
RAID groups. Auto-Rebuild uses drives assigned as Hot Spares,
followed by available drives, as automatic replacements for any
member that fails. Auto- Rebuild is disabled by default.
set RGAutoRebuild [GroupName | all] [enabled |
disabled]
get RGAutoRebuild [GroupName | all]
• R GCancelAddStorage (Immediate, Disabled on Error)
Cancels the RGAddStorage command.
RGCancelAddStorage [GroupName]
• R GCancelMediaScan (Immediate, Disabled on Error)
Cancels a media scan that is running on the specified existing
RAID group.
RGCancelMediaScan [GroupName]
• R GCommit (Immediate, Disabled on Error)
RGCommit stamps a new RAID group's configuration to its
member drives. Advanced Initialization is highly recommended
for new drives; this erases and verifies the drive media. The
RAID group is unavailable until the operation completes. Express
Initialization performs a background initialization and the RAID
group is immediately available for use. When RGCommit is
issued after adding storage, it stamps an existing RAID group's
configuration to the added drives, and initializes the drives if
Advanced or Express are specified. GroupName is the ASCII
name of the new RAID group to commit.
RGCommit <GroupName <advanced | express> | all
<advanced | express>>
