I'm looking to change the pool master because my current pool master is having some hardware issues. I've disabled HA and I came across this script to change the pool master to my other server: xe pool-designate-new-master host-uuid=[uuid]
My question is this: will changing the pool master take down the host (current pool master) or take down any of the VM's I've got running on it?

Changing the pool master won't take down the host or any of the VMs. It will cause a restart of the management service (XAPI) of all pool hosts, so that management access via Citrix XenCenter or CLI (xe commands) won't work for 10-30 seconds. Once the service is restarted, you can reconnect to the poolmaster or a slave via XenCenter (you'll be redirected to the new master).
