ISNSDD(8)						      System Manager's Manual							 ISNSDD(8)

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 com-
       mand 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

					     +--------+-----------------------------------------------------+
					     |socket  | network send/receive				    |
					     |auth    | authentication and security related information     |
					     |message | iSNS protocol layer				    |
					     |state   | database state					    |
					     |scn     | SCN (state change notification) messages	    |
					     |esi     | ESI (entity status inquiry) messages		    |
					     |all     | all of the above				    |
