As you know we only certified with VMware 3.5 with DSS V5 but we know others have it working. We only have documents with the upgrade to DSS V5 to V6 with VMware that is located from the link below, and this is due to the default SCST that the DSS V6 has where the DSS V5 is using the IET and you should not have a problem with your connections or LUNs not being seen from the VMware side especially if it writes it signiture on the LUN.
