RGHaltMediaScan
RGHaltMediaScan halts a media scan on the specified existing
RAID Group.
RGHaltMediaScan [GroupName]
RGHaltRebuild
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.
RGHaltRebuild [GroupName] <MemberIndex>
RGMediaScan
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.

RGMediaScanErrorReport
Displays error statistics for either a single RAID Group or all
RAID Groups in the system.

RGMemberAdd
RGMemberAdd adds available block devices to a NEW RAID
Group or as part of an RGAddStorage operation. GroupName is
the ASCII name of the RAID Group to receive the RAID
Member. BlockDevID is the index of an available block device
provided by the BlockDevScan CLI command. Up to 10
BlockDevIDs may be specified. If all is specified, then all
available unused BlockDevIDs will be added to the RAID Group
until the maximum number of RAID Group members has been
met. This command also resets the number of RAID Group
partitions to 1.
RGMemberAdd [GroupName] [BlockDevID | all] ...
RGMemberRemove
RGMemberRemove removes a RAID Member from a NEW
RAID Group. GroupName is the ASCII name of the NEW RAID
Group from which to remove the RAID Member. MemberIndex
is the index of the RAID Member to remove. This also resets the
number of partitions to 1.
RGMemberRemove [GroupName] [MemberIndex]
RGPrefetch
Set or Get the prefetch for all or for the specified RAID Group.
This command will fail if the RAID Group does not exist.
GroupName is the ASCII name of the RAID Group for which the
parameter will apply.
set RGPrefetch [GroupName | all] [Value 0 to 6]
get RGPrefetch [GroupName | all]
RGRebuild
RGRebuild starts rebuilding the specified existing RAID Group.
Optional parameters MemberN specify the members to rebuild.
If no member is specified, all degraded members will be rebuilt.
Optional parameters BlockDevIDN allows an available block
device to be substituted for the RAID Member currently
assigned to the Member Index. RAID 6 groups can rebuild two
members using the optional 'and'.
RGRebuild [GroupName] <Member1> <BlockDevID1>
<and> <Member2> <BlockDevID2>
RGRecover
RGRecover provides mechanisms for assisting in the read-only
access of data in OFFLINE RAID Groups. Specify "Rebuild" if
the RAID Group was rebuilding and the rebuild faulted. "Basic"
forces a RAID Group ONLINE with only up-to-date members
and returns CHECK CONDITION on READ errors. "Extreme"
forces a RAID Group ONLINE with older members and replaces
READ error data with zeros. "Disabled" turns off RGRecover for
"Basic" and "Extreme". NOTE: Before running RGRecover,
power off and power back on all drives in the affected RAID
Group drives to ensure the drives are at a known state and
ready for data recovery.
RGRecover [GroupName] [Rebuild | Basic | Extreme |
Disabled]
RGRecoverWithWrites
RGRecoverWithWrites performs the same functions as
RGRecover except the affected RAID Group allows WRITES to
the RAID Group to occur normally. NOTE: Care must be
exercised to minimize WRITE activity. Proceed with WRITEs at
your own risk.
RGRecoverWithWrites [GroupName] [Basic | Extreme]
RGResumeConversion
RGResumeConversion resumes the halted conversion on the
specified existing RAID Group.
RGResumeConversion [GroupName]
RGResumeErase
RGResumeErase resumes the erase on the specified existing
RAID Group.
