how to completely remove clustering while keeping all the VMs

Two server2012r2 nodes in an HA cluster, SAN storage.  Getting lots of event errors and occasionally vm's are unreachable.

I didn't build the cluster and I would like to rebuilt it.

But first I have to unbuild it.

I want to keep the nodes, keep all the VMs (running as much as possible), keep the VM drives on the SAN storage but I want to completely remove HA clustering... just have 2 separate nodes sharing the same storage device.

Can this be done?

Thanks.

First of all how are the hosts connected to the SAN? iSCSI or Fibre/SAS HBAs?

You can remove the HA role from the VM within the Failover Cluster Manager console but I think the VM has to be offline for you to do this.

If you're looking at rebuilding your cluster then I would personally remove the HA role from the VMs, export them, then re-import to local drives on the hosts while you go about recreating the cluster.
