Change Pool Master on Citrix XenServer

Published on 2009-02-04 in Xen. 0 Comments

Unless I’m overlooking something, there’s still no way to do this in XenCenter. Oh well, here’s how you do it from the command line:

First disable high availability:

xe pool-ha-disable

Now list your XenServer hosts:

xe host-list

Using the list above, designate a new pool master by supplying the uuid associated with the desired host:

xe pool-designate-new-master host-uuid=<uuid>

You’ll probably lose connection to the pool at this point, but that’s normal behavior. Once XenCenter reconnects (this should happen automatically), it’s safe to re-enable high availability:

xe pool-ha-enable
