--lld [driver] --op show --mode targetshow all the targets.

--lld [driver] --op new --mode=logicalunit --tid=[id] --lun=[lun] --backing-store [path]add a new logical unit with [lun] to specific target with [id]. The logical unit is offered to the initiators. [path] must be block device files (including LVM and RAID devices) or regular files. lun0 is reserved for a special device automatically created.
--lld [driver] --op delete --mode=logicalunit --tid=[id] --lun=[lun]delete specific logical unit with [lun] that the target with [id] has.
--lld [driver] --op bind --mode=target --tid=[id] --initiator-address=[address]add the address to the access lists of the target with [id]. Initiators with the address can access to the target. 'ALL' is a special address to allow all initiators to access to a target.
--lld [driver] --op unbind --mode=target --tid=[id] --initiator-address=[address]delete the address from the access lists of the target with [id].
--lld [driver] --op update --mode=target --tid=[id] --name=[parameter] --value=[value]change the value of [parameter] of the target with [id] to [value].
