Upgraded firmware on Smart Array P7xx (and some others) made them show up as SCSI revision 5 devices and this caused the driver to fail to map MSA2xxx logical drives to the correct bus/target/lun. A symptom of this would be that the target ID of the logical drives as presented by the external storage array is ignored, and all such logical drives are assigned to target zero, differentiated only by LUN. Some multipath software reportedly does not deal well with this behavior, failing to recognize different paths to the same device as such. Signed-off-by: Stephen M.
