RGSectorSize
Set or get the sector size of the specified RAID Group. The
desired RAID Group sector size must be evenly divisible by the
sector size of any member disk. 512 bytes is the default size for
most operating systems. Use 4 KB sectors to enable large
volume support (greater than 2 TB) in Windows XP (32-bit).
Usage: set RGSectorSize [GroupName] [512-8192]
get RGSectorSize [GroupName | all]
RGSpanDepth
Set or get the span depth on the specified existing NEW RAID
Group. All RAID Group types are supported except JBOD,
which implicitly supports spanning as members are added.
Usage: set RGSpanDepth [GroupName] [SpanDepth [1-16]]
get RGSpanDepth [GroupName | all]
RGSpeedRead
Perform look-ahead during reads from RAID Group member
disks for all or the specified RAID Group. GroupName is the
ASCII name of the RAID Group for which look-ahead reads will
be performed. Auto will choose the algorithm based on each I/O
command.
Usage: set RGSpeedRead [GroupName | all] [enabled |
disabled | auto]
get RGSpeedRead [GroupName | all]
RGUnmap (Immediate)
RGUnmap removes all of the mapped partitions of the specified
RAID Group or the specified RAID Group's partition or
contiguous partitions from the routing table. The partitions
themselves will be unaffected, though they will now be
inaccessible by any initiators.
Usage: RGUnmap [[[GroupName] <PartIdx] <2-128>>] | all]
RGWaitTimeout (OEM Configurable, Disabled on
Error)
The RGWaitTimeout field specifies the number of seconds
which the driver waits for devices to appear. The time out is
used during system boot and when the BlockDevScan
command is issued. You should adjust the time out setting when
you have more then one RAID group in a chassis so that the
chassis has enough time to bring all the drives involved in RAID
groups online. If not, there is a chance that the RAID adapter
may not discover all the drives for a RAID group and will either
fault or degrade the RAID group.
Usage: set RGWaitTimeout [1-300]
get RGWaitTimeout
RMStatus (Immediate)
RMStatus displays the status of all RAID Members within the
specified RAID Group or a specific RAID member (if specified)
within the specified RAID Group. This command will fail if the
specified RAID Group does not exist or a specified member
index within the RAID Group does not exist.
GroupName is the ASCII name of the RAID Group for which
status will be displayed.
Usage: RMStatus <[GroupName] <MemberIndex>>
Route (Immediate, OEM Configurable, Disabled on
Error)
Route is used to map a RAID Partition or SAS/SATA Pass
Through device to a Target ID on the host system. If a map with
the specified Target Id already exists, then it will be overwritten.
Use 'Delete' for a Target ID to remove the map.
Usage: Route host [tid] [ [RAID [GroupName] [PartIdx]] | [SAS
[SasIdx]] | Delete]
RouteDisplay (Immediate)
RouteDisplay will display a list of host protocol address to target
destination device mappings. The optional 'tid' parameter will
limit the list to the maps which satisfy a search for the given
Target ID. If the “Passthrough” parameter is entered then all
SATA/SATA Pass Through devices are displayed. Otherwise all
mapped RAID Partitions are displayed. If the “Persistent”
parameter is entered then only persistent maps will be
displayed. Otherwise both persistent and non-persistent maps
will be displayed.
Usage: RouteDisplay host < <tid> | <<passthrough>
<persistent>> >
SasPortList (Immediate)
SasPortList lists the status of all available SAS ports.
Usage: SasPortList
SASTargets (Immediate, Disabled on Error)
This command lists the physical devices that are connected to
all SAS ports.
Usage: SASTargets
SaveConfiguration (Immediate, Disabled on Error)
SaveConfiguration will save configuration changes. Please note
that certain modifications require a system restart.
Usage: SaveConfiguration
SerialNumber
SerialNumber displays the serial number. The serial number is
a 13 character field. The first seven alphanumeric characters
are an abbreviation representing the product name. The
remaining six digits are the individual system's number.
Usage: get SerialNumber
