You have a pool of Citrix Xen servers and you want to promote a server as pool master.

To control a pool of servers, you would need to connect to the pool master server.

Citrix Xen Server populates the management database among all the servers, however only one is the Master one.

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

1- Disable HA.

#xe pool-ha-disable

2- List UUID for all the hosts

#xe host-list

3- Promote slave to master

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

done !

If the pool Master is down:

#xe pool-emergency-transition-to-master

then re-establish the connection to the slaves.

# xe pool-recover-slaves
