Trying to decommission a VDI host but can't move the replica. No idea how to find what VM's it's associated with.

I have a VDI host that I am wanting to remove from my current View environment for another purpose. I can migrate all the VM's off of it no problem but there is a few replica disks left on it and I can't move them. I'm assuming migrate replicas isn't supported by vMotion. How else am I suppose to clear it off of there? I don't have a clue what VM's it is associated with and haven't found much for KB's describing how. If I rebalance that is only moving stuff around between datastore, not the host.

I tried this KB on the host I want to remove but the replicas that are showing still on the host were not listed in the output.

The replicas are protected from being vmotion. You have to unprotect the replica using sviconfig, vmotion it, then re-protect it after you're done.

Steps to unprotect

Manually deleting replica virtual machines in VMware Horizon View (1008704) | VMware KB

Steps to protect

Re-protecting a View replica virtual machine (2015006) | VMware KB

As far as which vms are using the replica...

You have to query the database to find that information

Actually, Replicas are supported for vMotion under a specific condition. A host needs to be placed in maintenance mode which is a good step to take before removing a host from the cluster. Check that DRS is set to "Fully Automated" and the replicas will be migrated. I have done this on too many hosts to count.

Great! I did as you mentioned and the replica did migrate with the rest of the hosts. Thank you for your response.
