• RGDiskWriteCache (Immediate)
If enabled, produces higher write performance with a small risk
of data loss after a system failure. If disabled, drives are updated
at the expense of some write performance.
set RGDiskWriteCache [GroupName | all] [enabled
| disabled]
get RGDiskWriteCache [GroupName | all]
• RGDisplay (Immediate)
Displays status information for a single RAID group, or if All is
used, all available RAID groups.
RGDisplay <GroupName | all>
• RGErase (Immediate)
Erases the data from the specified existing RAID group.
Warning: All data is lost when you use the RGErase command!
RGErase [GroupName]
• RGHaltConversion (Immediate)
Stops the conversion on the specified existing RAID group.
RGHaltConversion [GroupName]
• RGHaltErase (Immediate)
Stops the erase on the specified RAID group.
RGHaltErase [GroupName]
• RGHaltInitialization (Immediate)
Stops the initialization process on the specified existing RAID
group.
RGHaltRebuild [GroupName]
• RGHaltMediaScan (Immediate, Disabled on Error)
Halts a media scan on the specified existing RAID Group.
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 RAID 6
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 (Immediate, Disabled on Error)
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 rewritten 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.
RGMediaScan [GroupName] <verify | verify fix>
<[HH:MM] <day of week> <daily | weekly>>
• RGMediaScanErrorReport (Immediate, Disabled on Error)
Displays error statistics for either a single RAID Group or all
RAID Groups in the system.
RGMediaScanErrorReport [GroupName | all]
• RGMemberAdd (Immediate)
Adds available drives 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 drives 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 | all] [BlockDevID]
• RGMemberRemove (Immediate)
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]
