Hi Guys,
Would much appreciate your urgent help on this. I've got a crashed Windows Server 2012 Hyper-V 4 node lab cluster environment. The cluster was deployed on a single DC based domain which unfortunately crashed last week. Because of the absence of a Active Directory, access to the Failover Cluster Manager MMC is not possible as I need to be logged in to the domain to have access to the cluster components. Now I need to recover the VMs on one of the nodes. The plan is to recover the CSV which is being hosted by a NEXSAN ISCSI SAN and then retrieve the VHDX files. I can still can access the LUN hosting the Cluster storage. However when I try to bring the disk online via disk management I get the following message"specified disk or volume is managed by the Microsoft failover clustering component. The disk must be in cluster maintenance mode and the cluster resource status must be online to perform this operation."
Any information on how to bring the cluster storage disk online for a broken cluster instance would be appreciated.
Regards,
Buchi
