I previously had several VMs in a failover cluster in hyper-v utilizing a large Cluster Shared Volume. I need to take that CSV offline/away from Hyper-V failover cluster manager so that it can be accessed from another machine via iSCSI target. there are two nodes in this cluster but i'm not using the CSV or failover cluster to run any of the virtual machines right now. Those VMs are currently on another LUN that is simply seen by the operating system as an iSCSI disk. I don't want to cause any issues/outage within Hyper-V (again, 2 nodes right now that have the CSV I need to remove from the cluster) by shutting down the cluster service or removing the CSV from failover cluster manager.
So from within one of the two nodes in this cluster can I safely shutdown the failover cluster service or use the "take this resource offline" option without disrupting the Hyper-V service itself and the VMs that are currently running on one of those two nodes? Again, currently the VMs that are running on one of those two nodes aren't actually using a CSV or setup as a cluster. they are simply running in Hyper-V Manager and are stored on a non clustered iSCSI volume. I simply don't want to disrupt them or Hyper-V by removing the previously used CSV from Failover Cluster Manager.
Can I do this safely?
