One of the greatest features of Update Manager (4.0 U1 P1) is that you can click on a cluster and remediate the whole thing. It places one host @ a time into maintenance mode and does it’s thing. Unless of course Update Manager happens to be a VM that resides on one of those hosts in the cluster.
Example of Error:
- Update one host in your cluster manually
- Migrate the Update Manager VM to that updated host
- Remediate the entire cluster.
I like the fact that vCenter returns such an obvious error, but why can’t it move itself to another host like any other self-respecting VM.
