Hyper V Cluster error on validation - Cluster Disk 0 does not support Persistent Reservations


Busy validating a configuration before creating a hyper cluster. Two physical servers. Dell R720. Two Brocade switches. Dell MD3620f SAN. I have carved 16 LUNS. These can be seen on both servers. Configured MPIO with 4 paths. Failover config. 1 Active. 3 Standby paths.

Dell has verfified that the config on the SAN is correct.

The zones on the brocade swicthes have been configured correctly.

I get the following error when running the config validator - everything else passes:

Validate SCSI-3 Persistent Reservation

This unsually occurs when the SAN does not support SCSI-3 Persistent Reservation, and is not certified for use with Windows 2008 Clusters. It was a new feature which was introduced into Windows 2008 to make Cluster Verification easier.

But I've only seen it on non certified older SAN storage.

I would make enquiries as to whether a later version of storage firmware is required.
