DMX4 SCSI-3 Reservation - Whether “LU_SCOPE” is implemented??

When Linux hosts are trying to get SCSI3 reservation at DMX4 volumes, reservations are failing. While, we took End-To-End trace during the reservation, we can see that DMX4 is rejecting Persistent_Reserve_Out(Register) command sent by LINUX host. Here is the screenshot from the collected trace

As per standard if scope filed of CDB specifies a scope that is not implemented then command is terminated with check condition and additional sense code set to as “Invalid Field In CDB”

We are seeing the same failure as mentioned above. Scope field value used by host is “LU_SCOPE”. Now as per standard it is the correct value So it is clear that DMX4 is rejecting the register command.

Can any one confirm whether CDB field type “LU_SCOPE” is implemented or not with DMX4. If yes, than why I am seeing the failure. Director Port flags are as below -
