If you are passing the LUN to the VM with device='lun', the driver and VMM do not interpret any SCSI command. You should see exactly the same data as in the host, which includes support for SPC-3: >>> [root@localhost /]# sg_inq /dev/VM-IMAGES-BACKUP-DO-NOT-REMOVE/q_disk >>> standard INQUIRY: >>> PQual=0 Device_type=0 RMB=0 version=0x05 [SPC-3] >>> [AERC=0] [TrmTsk=0] NormACA=0 HiSUP=0 Resp_data_format=0 >>> SCCS=1 ACC=0 TPGS=1 3PC=0 Protect=0 [BQue=0] >>> EncServ=0 MultiP=0 [MChngr=0] [ACKREQQ=0] Addr16=0 >>> [RelAdr=0] WBus16=1 Sync=1 Linked=0 [TranDis=0] CmdQue=1 >>> length=36 (0x24) Peripheral device type: disk >>> Vendor identification: MacroSAN >>> Product identification: LU >>> Product revision level: 1.0 >>> Unit serial number: 0d9281ae-aea4-6da0-0000-02180142b300 Can you try using a Linux VM and executing sg_inq in the VM?
