All,
With VUM4 there doesn't seem to be any support for Scanning or Remediation tasks to take hosts in the Cluster out of Standby.
I am looking for advice from others on how they have handled this. We have hundreds of hosts that might shutdown during the night as backups are SAN based, so client loads across the infrastructure drop to minimal levels, and our Maintenance Windows are of course in the middle of the night.
The best answer I can sadly come up with is to disable DPM, Power On all the Standby Hosts and wait for them to be available. Scan and then Remediate, and once this is completed turn on DPM and allow it to Standby hosts again.
This seems quite time consuming waiting for potentially so many hosts to Power On before even attempting to proceed with the work, seems it would have been better for VMWare to build in a Power On feature with VUM4 to work with DPM.
Thank you for any advice.

according to the VMware vCenter Update Manager Administration Guide disabling DPM is the only option.
>If you are managing a cluster of hosts, make sure that Distributed Power Management is disabled. Otherwise, some of your hosts might not be patched.
Troy,
Thank you, that is what I had read as well. I didn't know if anyone had come up with any other solutions yet.
I will leave the discussion open for a little while longer.

Unfortunately UM doesn't take DPM in account at the moment. It's a known issue however, I can't give a date but it's definitely something that we at VMware are taking serious.

Duncan,
I always appreciate when you step into a conversation. I am glad you at least can share that it is a priority. This is very encouraging and I am looking forward to more information.
In the environment I work in, just 5-10% Host shutdown could result in thousands, if not hundreds of thousands if we can expand it, of dollars saved in energy costs but large manual processes can wipe out those same savings.
Thank you.

If and when I receive more info that I'm allowed to share I will most definitely put it up on my blog! No problem,
