The result from fedora 19 host and fedora 19 vm are the same. It's that means I got a wrong windows vm scsi pass-through driver? Or is there any tool like sg_inq in windows 2008? On Tue, Aug 20, 2013 at 8:09 PM, Paolo Bonzini <pbonzini@redhat.com> wrote:

Thanks, the whole iSCSI LUN have been passed to the VM.
But I test it with scsicmd, and found that the driver may be not support SPC-3, but if i use this by microsoft iscsi initiator, I can pass all the scsi3_test tests.
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?
