Users are advised to use .Xr iscsictl 8 instead. .Ef .Pp Internet SCSI (iSCSI) is a network protocol standard, that allows the use of the SCSI protocol over TCP/IP networks, the .Nm program is the userland side of an iSCSI session, see .Xr iscsi_initiator 4 . It has 2 modes of operation, if -d (discovery session) is specified, it will print out the .Em target names returned by the target and exit. In the second mode, it will, after a successful login/negotiation, run in daemon mode, monitoring the connection, and will try to reconnect in case of a network/target failure. It will terminate/logout the session when a SIGHUP signal is received. The flags are as follows: .Bl -tag -width variable=value .It Fl c Ar file a file containing configuration .Em key-options , see .Xr iscsi.conf 5 . .It Fl d do a .Em discovery session and exit. .It Fl n Ar nickname if .Sy -c file is specified, then search for the block named .Em nickname in that file, see .Xr iscsi.conf 5 . .It Fl p Ar pidfile will write the process ID of the session to the specified .Em pidfile .It Fl t Ar target the target's IP address or name. .It Fl v verbose mode. .It Ar variable Ns = Ns Ar value see .Xr iscsi.conf 5 for the complete list of variables/options and their possible values. .El .Sh EXAMPLES .Dl iscontrol -dt myiscsitarget .Pp will start a .Em discovery session with the target and print to stdout the list of available targetnames/targetadresses. Note: this listing does not necessarily mean availability, since depending on the target configuration, a discovery session might not need login/access permission, but a .Em full session certainly does. .sp .Dl iscontrol -c /etc/iscsi.conf -n myiscsi .Pp will read options from .Pa /etc/iscsi.conf , use the targetaddress found in the block nicknamed myiscsi, login and negotiate whatever options are specified, and start an iscsi-session. .Sh SEE ALSO .Xr da 4 , .Xr iscsi_initiator 4 , .Xr sa 4 , .Xr iscsi.conf 5 , .Xr iscsictl 8 , .Xr camcontrol 8 .Sh STANDARDS RFC 3720 .\"Sh HISTORY .Sh BUGS .Nm should probably load the iscsi_initiator module if needed. .br Not all functions/specifications have been implemented yet, noticeably missing are the Task Management Functions. The error recovery, though not .Em fully compliant does a brave effort to recover from network disconnects.
