It isn't just when it fails.  They move when you add
or remove other disks with lower scsi ID's or on
a controller that is detected earlier.  I have seen
that, but the reason - and fix - was always obvious
since it was a direct result of hardware changes, unlike
the failure to boot that may or may not happen depending
on the prior contents of a disk you are adding in a
non-boot position.
