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 target, 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.
