EMC VNX NAS and NetBackup 7.7.x SCSI reserve configuration

Hello, friends.  I've reviewed Veritas' and EMC's documentation but not found the answer (yet) to this question, so I'm posting it here.

I want to validate that EMC VNX NAS datamover configuration for enabling "scsiReserve" is compatible with my media servers' SPC-2 SCSI reserve option (currently selected.)  I'm believing this to be the case, but not finding a lot of concrete information to support that belief.

Any suggestions of where to look ?

    Celerras and VNXes have always worked fine with SPC-2. However, it's just wrong place to ask about features of DART OS - NBU supports both SPC-2 and persistent reservations, with the latter is considered a bit better, especially if you run clusters, but to work they just need to match on the filer in NBU. For the confirmation that DART can do SCSI-3 PR you need to reach out to EMC.
