Changing pool master

Go to the slave server that you want to use as pool master.

First disable HA on your XenServer Pool.

#xe pool-ha-disable

Now list UUID for all the hosts

#xe host-list

To designate a slave XenServer as the new pool master

# xe pool-designate-new-master host-uuid=("enter UUID number - without quotes"

If your pool master is down or unavailable, log in to a slave XenServer and enter the command below.

#xe pool-emergency-transition-to-master

Nopw you need to re-establish all connections to the slaves from the new pool master.

# xe pool-recover-slaves
