Cluster Service Hanging

Question

Hi,

Our Clustered Servers suddenly started facing problems accessing SAN Storage Disks from C:\ClusterStorage. If we shut down one of the 2 cluster Nodes, it works fine with a single server but the problem comes back after starting the 2nd node. We have 2 nodes cluster with hyper-v installed and another 2 nodes cluster without hyper-v. It is happening with both the clusters. Both the clusters are connected to separate SAN Storage Devices.

When we try to shut down any server, it gets stuck on shutting down the cluster service. Then we have to manually kill the cluster service to restart the server.

Any Suggestions?

Thanks.
