     iscsi - iSCSI initiator

     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):


     The iscsi subsystem provides the kernel component of an iSCSI initiator,
     responsible for implementing the Full Feature Phase of the iSCSI
     protocol.  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 following variables are available as both sysctl(8) variables and
     loader(8) tunables:

             Verbosity level for log messages from the iscsi driver.  Set to 0
             to disable logging or 1 to warn about potential problems.  Larger
             values enable debugging output.  Defaults to 1.

             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.  Set to 0 to disable sending
             NOP-Out PDUs.  Defaults to 5.

             The number of seconds to wait for iscsid(8) to establish a
             session.  After that time iscsi will abort and retry.  Defaults
             to 60.

             The number of seconds to wait for a login attempt to succeed.
             After that time iscsi will abort and retry.  Defaults to 60.

             The maximum number of outstanding IO requests.  Defaults to 255.

             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.

     The iscsi subsystem first appeared in FreeBSD 10.0.

     The iscsi subsystem was developed by Edward Tomasz Napierala
     <[email protected]> under sponsorship from the FreeBSD Foundation.
