Sangeetha Hariharan closed CLOUDSTACK-4643.
-------------------------------------------
Tested with latest build from 4.2-forward.
When master host is put in maintenance mode , it continues to remain the pool
master even after it is successfully put in maintenance mode and the all vms
from this host are live migrated to other hosts in the cluster.
> When the master host is put in maitenance mode , another host in the pool is
> set as master. This is with manage.xenserver.pool.master set to false.

> When the master host is put in maitenance mode , another host in the pool is
> set as master. This is with manage.xenserver.pool.master set to false.
> Steps to reproduce the problem:
> Advanced zone set up with 2 Xenserver hosts (6.0.2) in cluster.
> I want to upgrade the Xenserver hosts to 6.2.
> Followed these steps:
> 1. Edit the file /etc/cloudstack/management/environment.properties and add
> the following :
> manage.xenserver.pool.master=false
> 2. Restart management server.
> 3. Put the Master Host (H1) in maintenance mode.
> This results in the all the Vms in this host to migrate to another host (H2).
> It also results in making the other host (H2) in the cluster as the Master
> of this pool.
> 4. Unmanage the cluster.
> 5. Try to upgrade the host (H1) that was put in maintenance mode.
> Upgrade complains saying that the master host of the pool should be upgraded
> before this host can be upgraded.
> Step 3 which is putting Master Host (H1) to maintenance mode should not have
> resulted in changing the master of the pool to another host.
