.Dd September 11, 2014 .Dt ISCSI 4 .Os .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: d -ragged -offset indent .Cd "device iscsi" .Ed
p Alternatively, to load the driver as a module at boot time, place the following line in .Xr loader.conf 5 : d -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: l -tag -width indent t 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. t 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. t 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. t Va kern.iscsi.maxtags The maximum number of outstanding IO requests. t 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. .El .Sh SEE ALSO .Xr iscsi.conf 5 , .Xr iscsictl 8 , .Xr iscsid 8 .Sh HISTORY The .Nm subsystem first appeared in .Fx 10.0 . .Sh AUTHORS The .Nm subsystem was developed by .An Edward Tomasz Napierala Aq Mt trasz@FreeBSD.org under sponsorship from the FreeBSD Foundation.
