Subject: [PATCH] opensm/osm_state_mgr.c: Don't signal DISCOVER to SM state machine when already DISCOVERING
Date: Mon, 4 Oct 2010 09:16:44 -0400	[thread overview]
Message-ID: <20101004131644.GA24620@comcast.net> (raw)


Eliminate this "illegal" state machine transition which triggers the following
log message:

sm_state_mgr_signal_error: ERR 3207: Invalid signal OSM_SM_SIGNAL_DISCOVER in state DISCOVERING

This is observed when the SM port is down.
