As root:
echo N >/sys/class/scsi_disk/D:D:D:D/capacity_override
where N is the number of blocks and D:D:D:D is the device name
corresponding to the sdX disk. Or if you prefer, an equivalent path
would be
/sys/block/sdX/device/scsi_disk/D:D:D:D/capacity_override
and here you wouldn't have to guess at the value of D:D:D:D because it
would be the only entry in the /sys/block/sdX/device/scsi_disk
directory.
