iscsid —
interface to kernel iSCSI driver
The iSCSI initiator runs as a kernel driver, and provides access to iSCSI
  targets running across a network using the iSCSI protocol, RFC 3720. The
  iscsid utility itself interfaces to the kernel iSCSI
  driver, and also communicates, using
  isns(3), with the iSCSI name
  service running on other hosts to locate services and iSCSI instances. In
  normal operation, iscsid is a standard daemon, and
  will detach from the controlling terminal using
  daemon(3) and then loops,
  reading requests, processing them, and sending responses. Communication takes
  place over a Unix domain socket. iscsid exits on
  receiving a terminate message, (no response to one that is sent to the
  kernel), or when an error occurs reading from or writing to the socket.
The -d flag increases the log level to
    lvl. At level 0 only start and stop messages are
    logged. The -D flag causes
    iscsid to remain in the foreground and to write log
    output to stdout.
It is envisaged that user-level communication take place with
    iscsid using the
    iscsictl(8) utility, rather
    than directly over its communication socket. An example of setting up the
    in-kernel iSCSI initiator is shown in
    iscsictl(8).
The iscsid utility appeared in NetBSD
  6.0.
