Hi Peter!

Thanks for the detailed bug report.

The puzzling thing is that the patch in question restores the original
behavior in which we do not attempt to query any pages not explicitly
reported by the device.

Can you please send me the output of:

# sg_vpd -a /dev/sda
# sg_readcap -l /dev/sda

where sda is one of the aacraid volumes.

Thanks!
