Hi everyone,

Please review the fix for bug 6817566 
(http://bugs.opensolaris.org/view_bug.do?bug_id=6817566)
*Synopsis* -
CMM: Halting this node because door_ki_open of 
/etc/cluster/qd_userd_door returned error 22.

You can access the webrev at :
http://cr.opensolaris.org/~samnayak/webrev-6817566/


Explanation of the fix
--------------------------------
The ping check is done by CMM automaton in begin state of every 
reconfiguration.
CMM automaton executes the ping using a userland daemon qd_userd.

During a shutdown, the daemon could have been gone by the time the 
automaton tries to do a ping check in begin state. The door_ki_open() 
for qd_userd done by automaton in begin state can fail then.

The automaton does not need to do the ping check when the node is 
shutting down (shutdown intent or commit flag is set in CMM). That is 
the fix implemented.


Thanks & Regards,
Sambit
