Symptom:

I am using Virtual Iron to connect to 2 DSS servers. I am getting the same Unique ID number for LUNs in different DSS servers and Virtual Iron is confused.

Solution:

Apply update 0257-dss_b.upd to DSS and then use the testing kernel.

Additional information:  This is a problem associated with Virtual Iron only, because the software checks the SCSI ID.
