+.Sh NAME
+.Nm iscsi
+.Nd iSCSI initiator
+.Sh SYNOPSIS
+To compile this driver into the kernel,
+place the following line in the
+kernel configuration file:
+.Bd -ragged -offset indent
+.Cd "device iscsi"
+.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_load="YES"
+.Ed
+.Sh DESCRIPTION
+The
+.Nm
+subsystem provides the kernel component of an iSCSI initiator.
+The initiator is the iSCSI client, which connects to an iSCSI target,
+providing local access to a remote block device.
+The userland component is provided by
+.Xr iscsid 8
+and both the kernel and userland are configured using
+.Xr iscsictl 8 .
+The
+.Nm
+subsystem is responsible for implementing the
+.Qq Full Feature Phase
+of the iSCSI protocol.
+.Sh SYSCTL VARIABLES
+The following variables are available as both
+.Xr sysctl 8
+variables and
+.Xr loader 8
+tunables:
+.Bl -tag -width indent
+.It Va 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.
+.It Va kern.iscsi.iscsid_timeout
+The number of seconds to wait for
+.Xr ctld 8
+to establish a session.
+After that time
+.Nm
+will abort and retry.
+.It Va kern.iscsi.login_timeout
+The number of seconds to wait for a login attempt to succeed.
+After that time
+.Nm
+will abort and retry.
+.It Va kern.iscsi.maxtags
+The maximum number of outstanding IO requests.
+.It Va 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.
