Clear-ClusterDiskReservation is a diagnostic tool and should rarely if ever be need to be used.  It's really only needed if there is a lingering stale PR on the disk.  If you run the cluster Validation tool when you are having an issue with storage, it will give you insight to the problem... including if there is a stale PR

Thanks!

I think that disk manager will show you if your disk is reserved.

If you want to unreserve your disk, use the failiver cluster first, and remove the disk from cluster storage.

If the disk still reserved after that, use the clear-clusterdiskreservation

Hi Jorge Martín San Jose,

You can run the cluster validation then you will found “Validate SCSI-3 Persistent Reservation” error in the validation report, you can refer the following relate article to resolve this issue.
