Celerra Network Server Command Reference Manual
-target -info {<alias_name> | -all}
Displays attributes such as alias, iSCSI name, serial number, portal
group tag, network portal, and details about logical units and
connected initiators for all targets or the specified target.
-target -stat {<alias_name> | -all}
Displays statistical attributes such as initiator login/logout statistics
and iSCSI session statistics for all targets or the specified target.
-target -list
Displays a listing of all targets.
Enter -lun to display LUN options. The Celerra Network Server
supports LUNs up to 256.
-lun -number <lun_number> -create <target_alias_name> -size
<size> -fs <fs_name>
Creates a new logical unit number (LUN) and assigns it to an existing
target specified by the <target_alias_name>. The <lun_number> can
be an integer within the range of 0 to 255, but must be unique on the
target or the command fails. The <size> specifies the size of the LUN
in megabytes (M, the default), gigabytes (G), or terabytes (T).
Maximum LUN size is 2 TB minus 1 MB. The <fs_name> specifies the
name of a mounted file system that will serve as the storage pool for
the LUN. When creating regular LUNs (the default LUN type), the
mounted file system must be able to support the size specified.
[-vp {yes|no}]
The -vp yes option creates a virtually provisioned iSCSI LUN
instead of a regular LUN. Regular LUNs reserve space on the file
system for the entire LUN at the time of creation, but virtually
provisioned LUNs do not reserve space. Virtually provisioned
LUNs can be created larger than the underlying file system;
however, when data is written to the virtually provisioned LUN,
the file system must have sufficient free space to contain the data.
The default is no.
