I'm running VMM 2012 SP1 (version 3.1.6020.0). The cluster in question are Windows Server 2012 Datacenter.
I performed maintenance on one of my Hyper-V failover clusters (installed KB's inthis article) and when I took one the nodes out of maintenance I successfully migrated VM's between the two via the Failover Cluster Manger console. However, I noticed that VMM still had the exclamation mark on the cluster name. I didn't noticed this until a couple of days later and now I'm trying to do a cross-cluster migration and it's not allowing me because VMM thinks the node is in maintenance. I've tried rebooting the VMM server, refreshing the cluster, refreshing all the VMMs and no luck. When I go into the Failover Cluster Manager on each of the cluster nodes, both nodes show in production (not in maintenance). Any ideas?
Note: the way that I took the node out of maintenance was via the Failover Cluster Manager console and NOT through VMM console, as the VMM server was unavailable at the time).
