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
