Symptom:

Open-E storage cannot pass Windows cluster Validation test

Problem:

Errors when validating that storage supports the SCSI-3 Persistent Reservation commands

The following errors appear on initiator site (Windows 2008 R2):

Validating Cluster Disk 0 for Persistent Reservation support

Registering PR key for cluster disk 0 from node sm-comm.mesmetlab.int

Failed to Register PR key for cluster disk 0 from node xx-xxxx.xxxxxxx.xx status 1

Cluster Disk 0 does not support Persistent Reservations.

Solution:

You need to switch the IETD iSCSI to SCST iSCSI. IETD does not support iSCSI 3 commands.

In order to do that, go to DSS console -> CTRL+ALT+W -> Tuning options -> iSCSI deamon options -> iSCSI solution and choose SCST iSCSI.

Open-E software impacted:  DSS V6
