How to change the pool master in a XenServer farm

First you have to disable HA on the pool

#xe pool-ha-disable

List the hosts in the pool

#xe host-list

Promote the new slave

**# xe pool-designate-new-master host-uuid=**

If the pool master is not available the switch has to be enforced to succeed.

#xe pool-emergency-transition-to-master

re-establish connectio to the slave hosts

#xe pool-recover-slave

You’re done!
