While Lab Manager 4 Host Spanning is a step in the right direction for more flexible load distribution across hosts in a Lab Manager 4 cluster, I find the process for entering maintenance mode counter intuitive, cumbersome, and at the beginning when I didn’t know what was going on, frustrating. Unsuccessful maintenance mode attempts have always been somewhat mysterious in the past because vCenter Server doesn’t give us much information to pinpoint the problem as far as what’s preventing the maintenance mode. This situation now adds another element to the complexity. VMware should have enough intelligence to disable Host Spanning for us in the event of a maintenance mode request, or at the very least, tell us to shut it off since it is conveniently and secretly enabled by default during host preparation. Of course, all of this information is available in the Lab Manager documentation, but who reads that, right?
