Virtualizaton?  Is there a possibility that if I ran the lpar as, not a
guested linux lpar, but a dedication linux lpar I wouldn't have this
issue?

Well, we normally only reboot every 8 weeks to allow maintenance.  We do
boot occasionally but mostly to duplicate this situation for IBM.  I have
the rebuild steps pretty well documented.  I have a reboot scheduled this
weekend and the documentation printed out.  I plan on being out of state
so we'll see how well my documentation is and how well they follow it.

I'd like to be able to script this, however I can't figure out how to do
that either.  And my previous inquiries to the list as to how, didn't
really fly.

Let me first say that yes this is annoying, and should not happen. I guess
there is very little you can do in a virtualised environment as 5i lpar's
are.

Now just for the record, how often do you reboot? I tend not to reboot on
a
daily or even monthly basis, it's 24*7 production environment....

Now for a 'work-arond'.... you could possibly quite easily build a server
script to do a bunch of 'update drive..... serial=autodetect' things and
run
that after every reboot.... My guess being that you don't daily change the
number of drives either....
