iscsi-target

ISCSI-TARGET(8) 					    BSD System Manager's Manual 					   ISCSI-TARGET(8)

NAME

     iscsi-target -- service remote iSCSI requests

SYNOPSIS

     iscsi-target [-46DV] [-b block length] [-f configuration file] [-p port number] [-s maximum number of sessions] [-t target name]
		  [-v verbose arg]

DESCRIPTION

     iscsi-target is the server for iSCSI requests from iSCSI initiators.  iscsi-target listens for discovery and login requests on the required
     port, and responds to those requests appropriately.

     Options and operands available for iscsi-target:

     -4      iscsi-target will listen for IPv4 connections, and respond back using IPv4.  This is the default address family.

     -6      iscsi-target will listen for IPv6 connections, and respond back using IPv6.

     -b blocksize
	     Specify the underlying block size for iSCSI storage which will be served.	The possible sizes are: 512, 1024, 2048, and 4096 bytes,
	     with the default being 512 bytes.

     -D      When this option is specified, iscsi-target will not detach itself from the controlling tty, and will not become a daemon.  This can
	     be useful for debugging purposes.

     -f configfile
	     Use the named file as the configuration file.  The default file can be found in /etc/iscsi/targets.  See targets(5) for more informa-
	     tion.

     -p port number
	     Use the port number provided as the argument as the port on which to listen for iSCSI service requests from initiators.

     -s maximum number of sessions
	     Allow the maximum number of sessions to be initiated when connecting to the target.

     -t filename
	     The target name (as it appears to the iSCSI initiator) can be specified using this flag.

     -V      iscsi-target will print the utility name and version number, and the address for bug reports, and then exit.

     -v argument
	     The amount of information shown can be varied by using this command.  Possible values of argument are net to show network-related
	     information, iscsi to show iSCSI protocol-related information, scsi to show SCSI protocol information, and all to show information
	     from all of the above arguments.

FILES

     /etc/iscsi/targets 	the list of exported storage
     /var/run/iscsi-target.pid	the PID of the currently running iscsi-target

SEE ALSO

     targets(5)

HISTORY

     The iscsi-target utility first appeared in NetBSD 4.0.
