iscsi

ISCSI(4)						   BSD Kernel Interfaces Manual 						  ISCSI(4)

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.
