Appendix A - CLI ASCII-Based Interface
• RAIDRebuildPriority
Sets 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.
set RAIDRebuildPriority <GroupName | all> [high
| low | same]
get RAIDRebuildPriority <GroupName | all>
• RAIDSpeedWriteLimit
Set or get 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
• Reserve (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 on
the unit.
Reserve
• RestoreConfiguration (Immediate, Disabled on Error)
Issued with the default option, forces the NVRAM settings to
their original defaults. The "saved" option undoes any changes
made to this session since the last save.
RestoreConfiguration [Default | Saved]
• RGAddStorage (Immediate)
RGAddStorage 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>
• RGAutoRebuild
RGAutoRebuild 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 set RGAutoRebuild [GroupName | all]
• RGCancelAddStorage (Immediate, Disabled on Error)
Cancels the RGAddStorage command.
RGCancelAddStorage [GroupName]
• RGCancelMediaScan (Immediate, Disabled on Error)
Cancels a media scan that is running on the specified existing
RAID Group.
RGCancelMediaScan [GroupName]
• RGCommit (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> >
• RGCreate (Immediate)
Creates a NEW empty RAID group. GroupName is an ASCII
name for the RAID Group (14 chars max, no spaces). The
optional value after the RAID Group type parameter represents
the desired interleave for the RAID Group. KB denotes
interleave in kilobytes; without the KB suffix, interleave is set in
512 byte blocks. If interleave is not provided, the system-default
interleave is used.
RGCreate [GroupName] [RAID [ 0 | 1 | 10 | 4 | 5
| 6 ] | JBOD] <8KB | 16KB | 32KB | 64KB | 128KB
| 256KB | 512KB | 1024KB | 2048KB>
