Logical block size of a SCSI disk should never be larger than physical block size. From an ATA/SCSI perspective, it makes no sense to have the logical block size greater than the physical block size, and it cannot even be effectively expressed in the command set. The whole point of adding the physical block size to the ATA/SCSI command set was to communicate a desire for a larger block size (than logical), while maintaining backwards compatibility with legacy 512 byte block size. When setting logical_block_size > physical_block_size, QEMU cannot express it in READ CAPACITY(16) output, and all it can do is set the physical block exponent to 0 (i.e. logical_block_size == physical_block_size). Reporting the error properly, however, is better. Signed-off-by: Mark Kanda <mark.kanda@oracle.com> Reviewed-by: Konrad Rzeszutek Wilk <konrad.wilk@oracle.com> Reviewed-by: Martin K.
