Re: [libvirt-users] Oracle RAC in libvirt+KVM environment
From the fedora 19 host:
[root@fedora ~]# sg_inq /dev/sdc
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

Product identification: LU
Product revision level: 1.0
Unit serial number: fd01ece6-8540-f4c7-0000-fe170142b300
From the fedora 19 vm:
[root@fedoravm ~]# sg_inq /dev/sdb
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

Unit serial number: fd01ece6-8540-f4c7-0000-fe170142b300
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?

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:

Can you try using a Linux VM and executing sg_inq in the VM?
