6:57 a.m.
I found when I use "scsicmd -d1 -s13" test command to test the
"controller bus reset" request, there will be a blue screen on windows
2008 r2.
The error code is :

DRIVER_IRQL_NOT_LESS_OR_EQUAL (d1)
An attempt was made to access a pageable (or completely invalid) address at an
interrupt request level (IRQL) that is too high. This is usually
caused by drivers using improper addresses.

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.
Tool can be found here:
http://www.symantec.com/business/support/index?page=content&id=TECH72086
It's this means that the scsi passthrough windows driver does not
support SPC-3 feature, I have read a post about this, it says if
support this we should change both the implementation and the
documents in virtio spec.
I am new to this list, so I don't know what is the situation right now?
Would somebody please give me some advise on it?
