NAME

     iscsi -- iSCSI initiator

SYNOPSIS

     To compile this driver into the kernel, place the following line in the kernel configuration file:

	   device iscsi

     Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):

	   iscsi_load="YES"

DESCRIPTION

     The iscsi subsystem provides the kernel component of an iSCSI initiator.  The initiator is the iSCSI client, which connects to an iSCSI tar-
     get, providing local access to a remote block device.  The userland component is provided by iscsid(8) and both the kernel and userland are
     configured using iscsictl(8).  The iscsi subsystem is responsible for implementing the "Full Feature Phase" of the iSCSI protocol.

SYSCTL VARIABLES

     The following variables are available as both sysctl(8) variables and loader(8) tunables:

     kern.iscsi.ping_timeout
	     The number of seconds to wait for the target to respond to a NOP-Out PDU.	In the event that there is no response within that time
	     the session gets forcibly restarted.

     kern.iscsi.iscsid_timeout
	     The number of seconds to wait for ctld(8) to establish a session.	After that time iscsi will abort and retry.

     kern.iscsi.login_timeout
	     The number of seconds to wait for a login attempt to succeed.  After that time iscsi will abort and retry.

     kern.iscsi.maxtags
	     The maximum number of outstanding IO requests.

     kern.iscsi.fail_on_disconnection
	     Controls the behavior after an iSCSI connection has been dropped due to network problems.	When set to 1, a dropped connection causes
	     the iSCSI device nodes to be destroyed.  After reconnecting, they will be created again.  By default, the device nodes are left
	     intact.  While the connection is down all input/output operations are suspended, to be retried after the connection is reestablished.

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

HISTORY

     The iscsi-target utility first appeared in NetBSD 4.0.
