NAME

       isnsdd - iSNS discovery daemon

SYNOPSIS

       isnsdd [-f] [-c filename] [-d debug-facility]

DESCRIPTION

       Isnsdd  is  a client side daemon for iSNS. It registers storage nodes and portals with the
       iSNS service, and refreshes these registrations in a timely manner.

       The daemon also registers itself to receive SCN notifications, and processes these. It can
       be  configured  to  invoke  an  external  helper  application for each status notification
       received. The path name of the helper application can  be  specified  via  the  SCNCallout
       option in the configuration file.

OPTIONS

       By   default,   isnsd  will  take  most  of  its  settings  from  the  configuration  file
       /etc/isns/isnsdd.conf, with the addition of the following command line options:

       --config filename, -c filename
              This option overrides the default configuration file.

       --foreground,-f
              By default, isnsd will put itself into the background. By specifying  this  option,
              you  can  tell it to run in the foreground. Any error messages or debug output will
              be printed to the console rather than being sent to syslog.

       --role role
              This tells the discovery daemon in which capacity is should  register  itself  with
              the  iSNS  server.   Role  can  be either initiator, or control.  The default is to
              register as an initiator.

              Registering target nodes needs to use a different mechanism, as  the  iSCSI  target
              server  needs to inform the discovery daemon about each exported target separately.
              This is not implemented yet.

       --debug facility, -d facility
              enables debugging. Valid facilities are
