I have a 5 node cluster with a shared clustered disk connect to a dell equalogic ps4000i. I was doing maintenance on one of the nodes (node 3), which happened to be the node owner of the clustered shared volume. I manually did a live migration of all the virtual machines one at a time. Once completed, I selected Pause and then the option to drain the roles to move the clustered shared volume to another server.
While this was in progress, I noticed that all of the virtual machines started to go offline. the failover cluster manager showed that the ownership has moved to node 1. when I checked the status of node 1, the clustered disk was showing online
(no access).any thoughts? It took me about 15 minutes to get things back up but I had to manually move it to another node before it connected in successfully
