We have a problem that during the back-up of our 4 node Hyper-v cluster, the CSV's are placed in redirected mode and do not return back in the normal state when the back-up finishes on one of the nodes. When a new back-up is started on one of the other nodes in the cluster, normally the back-up should not start because the luns are locked by the other host because this host has the luns in redirected mode. In Our case the back-up is starting on the other host and after trying to claim the luns our csv's are disappearing on the cluster and the vm's are crashing. Has anyone experienced the same issue? Is there a solution?
We are using Hyper-v 2008 R2 with HP Dataprotector 8.x and 3PAR VSS Provider.
