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
