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.
