             Summary: Host is still marked as being in "Up" state when the host 
is shutdown (when there are no more hosts in the cluster)
                 Key: CLOUDSTACK-2140
                 URL: https://issues.apache.org/jira/browse/CLOUDSTACK-2140
             Project: CloudStack
          Issue Type: Bug
      Security Level: Public (Anyone can view this level - this is the default.)
    Affects Versions: 4.2.0
         Environment: build from master
            Reporter: Sangeetha Hariharan
             Fix For: 4.2.0


Host is still marked as being in "Up" state when the host is shutdown (when 
there are no more hosts in the cluster.

Set up:

Advanced zone.
3 hosts in a cluster ( in my case host id - 7 ,8 ,9 ).

I did not have any problems when host 8 and host 9 where shutdown.

When I tried to shutdown host 7 , I see the host still being in "Up" state , 
even after the management server detected that it is not able to connect with 
this host.

Following exception seen in management server logs:
