+		add a new target with <id> and <name>. <id> must not be zero.
+	--lld <driver> --mode target --op delete [--force] --tid <id>
+		delete the specific target with <id>.
+		With force option, the specific target is deleted
+		even if there is an activity.
+	--lld <driver> --mode target --op show
+		show all the targets.
+	--lld <driver> --mode target --op show --tid <id>
+		show the specific target's parameters.
+	--lld <driver> --mode target --op update --tid <id> --name <param> --value <value>
+		change the target parameters of the target with <id>.
+	--lld <driver> --mode target --op bind --tid <id> --initiator-address <address>
+	--lld <driver> --mode target --op bind --tid <id> --initiator-name <name>
+		enable the target to accept the specific initiators.
+	--lld <driver> --mode target --op unbind --tid <id> --initiator-address <address>
+	--lld <driver> --mode target --op unbind --tid <id> --initiator-name <name>
+		disable the specific permitted initiators.
+	--lld <driver> --mode logicalunit --op new --tid <id> --lun <lun>
+	--backing-store <path> --bstype <type> --bsopts <bs options> --bsoflags <options>
+		add a new logical unit with <lun> to the 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.
+		bstype option is optional.
+		bsopts are specific to the bstype.
+		bsoflags supported options are sync and direct
