The userland companion is .Xr iscontrol 8 , and permits access to remote .Em virtual SCSI devices via .Xr cam 4 . .Sh SYSCTL VARIABLES .Bl -tag -width "net.iscsi.n.targedaddress" .It Va debug.iscsi_initiator set the debug-level, 0 means no debugging, 9 for maximum. .It Va net.iscsi.isid the initiator part of the Session Identifier. .El .Pp The following are informative only: .Bl -tag -width "net.iscsi.n.targedaddress" .It Va net.iscsi.driver_version the current version of the driver. .It Va net.iscsi.sessions the number of current active sessions. .It Va net.iscsi.n.targetname the target name of session .Em n . .It Va net.iscsi.n.targedaddress the IP address of the target of session .Em n . .It Va net.iscsi.n.stats statistics for session .Em n .It Va net.iscsi.n.pid the .Em "process id" of the userland side of session .Em n , see .Xr iscontrol 8 . .El .Sh FILES The .Nm driver creates the following: .Pp .Bl -tag -width ".Pa /dev/iscsi%dxx" -compact .It Pa /dev/iscsi used to create new sessions. .It Pa /dev/iscsi%d for each new session. .El .Sh SEE ALSO .Xr cam 4 , .Xr camcontrol 8 , .Xr iscontrol 8 .Sh STANDARDS iSCSI RFC 3720 .\" .Sh HISTORY .\" .Sh AUTHORS .Sh BUGS The lun discovery method is old-fashioned.
