Is "Maintenance mode" just broken in ESX 3.5 / VC 2.5? i'm getting REALLY odd results. A while back I i was having problems with update manager. I'd run it and it would just sit there. it wouldn't migrate any VM's off the host. I'd put the host in maintenance mode and it would just sit there and do nothing. After i manually migrated things off and patched the servers, vmotion seemed to work better. Today, I put a fully patched host into maintenance mode. I watched it migrate a couple of VMs. a while later I went back and saw that the host says (maintenance mode). I almost powered the thing off. There's still 11 VMs running on the host !!!! No errors ...... Nothing. Did I mention that I almost powered the thing off !!! I'm seriously considering going back to 3.0 at this point.
