cfiscsi — CAM Target Layer iSCSI target frontend

       The cfiscsi subsystem was developed by Edward Tomasz Napierala <trasz@FreeBSD.org> under sponsorship from
       the FreeBSD Foundation.  This manual page was written by Enji Cooper <ngie@FreeBSD.org>.

Debian                                            May 28, 2017                                        CFISCSI(4)

       The  cfiscsi subsystem provides the kernel component of an iSCSI target.  The target is the iSCSI server,
       providing LUNs backed by local files and volumes  to  remote  initiators.   The  userspace  component  is
       provided  by  ctld(8).   cfiscsi  is implemented as a ctl(4) frontend and uses infrastructure provided by
       iscsi(4).

       The  cfiscsi  subsystem first appeared in FreeBSD 10.0 as part of the ctl(4) driver.  It was split off of
       ctl(4) in FreeBSD 12.0.

ctl(4), iscsi(4), ctl.conf(5), ctld(8)

       To compile this driver into the kernel, place the following lines in your kernel configuration file:

             devicecfiscsidevicectldeviceiscsi

       Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):

             cfiscsi_load="YES"

       The following variables are available as both sysctl(8) variables and loader(8) tunables:

       kern.cam.ctl.iscsi.debug
               Verbosity level for log messages from the kernel part of iSCSI  target.   Set  to  0  to  disable
               logging  or 1 to warn about potential problems.  Larger values enable debugging output.  Defaults
               to 1.

       kern.cam.ctl.iscsi.maxtags
               The number of outstanding commands to advertise to each iSCSI initiator.  Current  implementation
               is not very accurate, so do not set this below 2.  Defaults to 256.

       kern.cam.ctl.iscsi.ping_timeout
               The  number  of seconds to wait for the iSCSI initiator to respond to a NOP-In PDU.  In the event
               that there is no response within that time the session gets forcibly terminated.   Set  to  0  to
               disable sending NOP-In PDUs.  Defaults to 5.
