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.
Usage: set RGAutoRebuild [GroupName | all] [enabled |
disabled]
get RGAutoRebuild [GroupName | all]
RGCancelAddStorage (Immediate, Disabled on Error)
RGCancelAddStorage cancels the RGAddStorage command.
Usage: RGCancelAddStorage [GroupName]
RGCancelMediaScan (Immediate, Disabled on Error)
RGCancelMediaScan cancels a media scan that is running on
the specified existing RAID Group.
Usage: 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.
Usage: RGCommit < GroupName <Advanced | Express> | all
<Advanced | Express> >
RGCreate (Immediate)
RGCreate 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.
Usage: RGCreate [GroupName] [RAID[0|1|10|4|5|6]|JBOD]
<64KB|128KB|256KB|512KB|1024KB
|128|256|512|1024|2048>
RGDiskWriteCache
Enable RAID member disk Write Cache for higher write
performance with a small risk of data loss after a system failure.
Disable RAID member disk Write Cache to force the drives to
update the storage media at the expense of some write
performance.
Usage: set RGDiskWriteCache [GroupName | all] [enabled |
disabled]
get RGDiskWriteCache [GroupName | all]
RGDisplay (Immediate)
RGDisplay displays RAID Group status information.
GroupName is an ASCII name for an existing RAID Group.
Usage: RGDisplay <GroupName | all>
RGErase (Immediate)
RGErase erases the data from the specified existing RAID
Group. WARNING: All data will be lost!
Usage: RGErase [GroupName]
RGHaltConversion (Immediate)
RGHaltConversion halts the conversion on the specified
existing RAID Group.
Usage: RGHaltConversion [GroupName]
RGHaltErase (Immediate)
RGHaltErase halts the erase on the specified existing RAID
Group.
Usage: RGHaltErase [GroupName]
RGHaltInitialization (Immediate)
RGHaltInitialization halts the initialization of the specified RAID
Group.
Usage: RGHaltInitialization [GroupName]
RGHaltMediaScan (Immediate, Disabled on Error)
RGHaltMediaScan halts a media scan on the specified existing
RAID Group.
Usage: RGHaltMediaScan [GroupName]
RGHaltRebuild (Immediate)
RGHaltRebuild halts the rebuild(s) on the specified existing
RAID Group. Optional parameter MemberIndex specifies the
RAID Member whose rebuild will be halted. For RAID6 Groups,
if a MemberIndex is specified, all rebuilding RAID Members on
the span with that MemberIndex will halt as well. If no
MemberIndex is specified, all rebuilds on that RAID Group will
be halted.
Usage: RGHaltRebuild [GroupName] <MemberIndex>
RGMediaScan (Immediate, Disabled on Error)
RGMediaScan initiates a Media Scan. A Media Scan reads all
member drives and corrects Media Errors by calculating the
expected data and rewriting it, so the drive can relocate it to a
good sector. The 'verify' option adds a data integrity check by
verifying that the data and parity match. 'Verify' plus 'fix' causes
the parity to be re-written when a verify mismatch occurs. Enter
time (must be HH:MM in 24-hour time format) and day of week
without the 'daily/weekly' option to schedule a one-time scan for
a later date. Enter time, day of week and 'daily' or 'weekly' to
schedule a scan on a recurring basis.
Usage: RGMediaScan [GroupName] <verify | verify fix>
<[HH:MM] <day of week> <daily | weekly>>
