NAME

       tgt-admin - Linux SCSI Target Configuration Tool

SYNOPSIS

       tgt-admin [-e --execute] [--delete <value>] [--offline <value>] [--ready <value>] [-s --show] [-C --control-port <NNNN>] [-c --conf <file>]
		 [--ignore-errors] [-f --force] [-p --pretend] [--dump] [-v --verbose] [-h --help]

DESCRIPTION

       tgt-admin is a utility which allows a persistent configuration of targets and luns. It uses tgtadm commands to create, delete and show
       targets.

OPTIONS

       -e, --execute
	   Read /etc/tgt/targets.conf and execute tgtadm commands. If the target already exists, it won't be processed. See --update.

       -d, --delete <value>
	   Delete all or selected targets. The target will be deleted only if it's not used (no initiator is connected to it).

	   If you want to delete targets which are in use, you have to add the "--force" flag.

	       Example usage:
		   --delete ALL 	   - delete all targets
		   --delete tid=4	   - delete target 4
					     (target with tid 4)
		   --delete iqn.2008-08.com.example:some.target
					   - delete this target

       --offline
	   Put all or selected targets in offline state.

	       Example usage:
		   --offline ALL	   - offline all targets
		   --offline tid=4	   - offline target 4
					     (target with tid 4)
		   --offline iqn.2008-08.com.example:some.target
					   - offline this target

       --ready
	   Put all or selected targets in ready state.

	       Example usage:
		   --ready ALL		   - ready all targets
		   --ready tid=4	   - ready target 4
					     (target with tid 4)
		   --ready iqn.2008-08.com.example:some.target
					   - ready this target

       --update <value>
	   Update all or selected targets. The target will be updated only if it's not used (no initiator is connected to it).

	   If you want to update targets which are in use, you have to add "--force" flag.

	       Example usage:
		   --update ALL 	    - ready all targets
		   --update tid=4	    - ready target 4
					      (target with tid 4)
		   --update iqn.2008-08.com.example:some.target
					    - update this target

       -s, --show
	   Show all the targets.

       -C, --control-port <NNNN>
	   It is possible to run multiple concurrent instances of tgtd on a host. This argument is used to control which instance the tgt-admin
	   command will operate on.

       -c, --conf <configuration file>
	   Specify an alternative configuration file instead of /etc/tgt/target.conf, which is the default.

       --ignore-errors
	   Continue even if tgtadm exits with non-zero code.

       -f, --force
	   Force some operations even if the target is in use.

       -p, --pretend
	   Only print tgtadm options which would be used; don't execute any actions. Assumes -v.

       --dump
	   Dump current tgtd configuration. Note: does not include detailed parameters, like write caching.

       -v, --verbose
	   Increase verbosity (show tgtadm commands used).

       -h, --help
	   Display a list of available options and exit.

CONFIGURATION FILE SYNTAX

       The defualt configuration file is /etc/tgt/target.conf. It defines all the targets and their properties. The configuration file is in XML
       format and uses tags. Configuration file contains several target blocks, where each block contains target's properties such as storage
       devices, initator ACL and authorization information. You can include other config files using: include /etc/tgt/xen/*.conf.

       backing-store
	   Defines a virtual device on the target.

       direct-store
	   Defines a direct mapped device with the same properties as the physical device (such as VENDOR_ID, SERIAL_NUM, etc.)

       initiator-address
	   Allows connections only from the specified IP address. Defaults to ALL if no "initiator-address" is specified.

       incominguser
	   Define iscsi incoming authentication setting. If no "incominguser" is specified, it is not used.

       outgoinguser
	   Define iscsi outgoing authentication setting. If no "outgoinguser" is specified, it is not used.

	       Example configuration file:

	       <target iqn.2007-04.com.example:san.monitoring>
	       backing-store /dev/san/monitoring

	       # if no "incominguser" is specified, it is not used
	       incominguser backup secretpass12

	       # defaults to ALL if no "initiator-address" is specified
	       initiator-address 192.168.1.2
	       </target>

	       <target iqn.2007-02.com.example:san.xen1>
	       backing-store /dev/san/xen1-disk1 # LUN1
	       direct-store /dev/san/xen1-disk2  # LUN2

	       initiator-address 192.168.1.2	 # Allowed IP
	       initiator-address 192.168.5.6	 # Allowed IP

	       incominguser user1 secretpass12
	       incominguser user2 secretpass23

	       outgoinguser userA secretpassA
	       </target>

	       <target iqn.2007-02.com.example:san.xen2>
	       backing-store /dev/san/xen2
	       </target>

	       <target iqn.2007-06.com.example:san.vmware1>
	       backing-store /dev/san/vmware1
	       </target>
