If you attended my SRM session at VMworld 2014, or one of the VMUG User Conference sessions I’ve presented at, you’ve heard me talk about upgrading SRM and the entire infrastructure.
I stressed the importance of upgrading the Recovery/Target Site’s hosts before upgrading the Protected/Source Site’s hosts.
As you can imagine, upgrading out of order does happen, and I got to see exactly what happens when you’re in that situation. Well, not in a disaster, but in regular day-to-day tasks.
Have you seen this error when trying to protect a VM in SRM, specifically trying to create the placeholder?
Placeholder VM creation error: No hosts with hardware version ’10’ and datastore(s) [datastore01] which are powered on and not in maintenance mode are available
