Cluster Disk With Identifier (identifier) has a Persistent Reservation on it

One of my customer’s team member had destroy the Hyper-V Cluster by mistake. He formatted the cluster nodes without evict them before doing that . The nodes of the clsuter used to be  part of old cluster that was destroyed by mistake.

I tried to build the nodes again from the scratch and Create new cluster, When I run the validation wizard I got this error:

Cluster disk with identifier (identifier) has a persistent reservation on it ,the disk might be part of other cluster. removing the disk from other validation set.

My SAN is HP EVA. The Cluster is not able to see any of my LUNS although I can see them from disk management and can’t create the cluster.

This error due to the fact that the LUNs still keeping the old identifiers from the old cluster, You have to use Cluster command line to clear the reservation by that command:

cluster.exe node %nodename% /clear:disknumber

Now everything should work fine and you can pass the validation wizard 🙂
