That's what I meant by a possible VPD (vital product data) based tool.
The deal here is that you need to bind pathnames to specific partitions
on specific spindles. There are many ways to do this, but I've often thought
that perhaps the old mainframe folks had it right by having volume labels.
You already do something similar with ccd(4) devices (or similar on diff
platforms) by binding underlying physical volumes to the Nth logical
volume. It wouldn't be that hard to come up with a reasonable config
file format that could uniquely identify disks which could then be put
together and mounted.
