Thank you Nicholas.
But seems probably due to the TCMU I am using, I cannot get the VPD
page of the device. Is it the VPD page implemented per backstore, or
it should be there but I setup something wrong?

Hi Sheng,
TCMUv2 passes all opcodes to tcmu-runner, and tcmu-runner doesn't yet
implement vpd83, although it really should because it's mandatory in the
spec.
I've opened this issue:
https://github.com/agrover/tcmu-runner/issues/7
and will work to resolve this as soon as possible.
Thanks -- Regards -- Andy
