hi marco
no problemo, and thanks for the prompt replies. I'm just projecting
possibilities, trying to make it work for me. yet I'd like to avoid
looking for info that doesn't exist, which ironically takes the
longest to look for.

Why would you be adding removing drives all the time?
I plan to do a simple dump backup on a rotating set of HDs each
evening. Am I safe to assume that sata drives can be added after boot
with no loss in system integrity?
I have storage stuff for a living and this isn't hardly an issue to
me.
I promise you I change and replace a lot of disk too.
Is it possible to add a short entry in the official website's FAQ,
maybe under 'disk set up' or 'system management'?
I'm not good enough to write anything remotely technical unfortunately
and y experience is very lacking - to put it mildly.
With the reduced costs in having multiple drives, I'm sure it's
becoming a common issue for many.
Several things have been discussed in auto-detecting these drive
changes
but none are acceptable or too cumbersome. Consider this a WIP.
so i didn't think of it first :-)
i guess as a first step you'd need to tackle the simplest of
scenarios: only add drives with an MBR and a system containing the
minimum required partitions so that the boot process can continue, but
I can see a lot of issues cropping up even with my rudimentary
understanding
keep up the good work!

which
can be pretty frequent.
if the total number of drives in the system is not the same from
boot to
boot, i have to tweak fstab.
is it possible for a future update of OpenBSD to tweak fstab to take
references to the boot drive? that should help a lot in such cases. I
could spout a lot of ideas, like having a unique identifier
(combination
of timestamp and netcard/cpu id?) in the boot block for reference in
fstab, but i'm no expert.
Oh well i'll resign to your suggestions and follow a strict
workflow: no
superfluous drives at boot and add them just before backup should do
fine, unless anybody has a better idea. I'd hate keeping back-up
drives
in the machine for no apparent reason.
At least i don't have to spend more time searching for info as this
seems to be a dead end.
thanks for the feedback all round
regards

Right, assuming you don't have to change your boot device in BIOS
all
you have to do is do it in fstab.

why? It's just a number.
Any pointers to useful info would be greatly appreciated. I guess
i'll
have to mess with the BIOS and IRQs but these are, till now out of
my
radar.

Better not mess at all. Fix your fstab and all's well.
