SCSI disk detection is asynchronous on purpose since a long time. The
most recent commit I know of that changed SCSI disk scanning
behavior is commit f049cf1a7b67 ("scsi: sd: Rely on the driver core for
asynchronous probing").
Please use one of the /dev/disk/by-*/* identifiers as Damien requested.
Thanks,
Bart.
