.Sh NAME
.Nm iscsi_initiator
.Nd kernel driver for the iSCSI protocol
.Sh SYNOPSIS
To compile this driver into the kernel,
place the following lines in your
kernel configuration file:
.Bd -ragged -offset indent
.Cd "device iscsi_initiator"
.Ed
.Pp
Alternatively, to load the driver as a
module at boot time, place the following line in
.Xr loader.conf 5 :
.Bd -literal -offset indent
iscsi_initiator_load="YES"
.Ed
.Sh DESCRIPTION
.Bf -symbolic
This driver, along with its userspace counterpart
.Xr iscontrol 8 ,
is obsolete.
Users are advised to use
.Xr iscsi 4
instead.
.Ef
.Pp
The
.Nm
implements the kernel side of the Internet SCSI (iSCSI) network
protocol standard, 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 ".Va net.iscsi.n.targeaddress"
.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.
.It Va "kern.cam.cam_srch_hi=1"
allow search above LUN 7 for SCSI3 and greater devices.
.It "the following are informative only:"
.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
is the targe name of session
.Em n .
.It Va net.iscsi.n.targeaddress
is the IP address of the target of session
.Em n .
.It Va net.iscsi.n.stats
are some statistics for session
.Em n
.It Va net.iscsi.n.pid
is 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.
