With all the upheaval here this week, I misplaced alan's replies about the
MRU and the tl822(sorry alan). I included them in there entirety below.
After posting the summary, I recieved a quick not from someone who did a 40g
to 5.1A with no issues.

MRU is the Media Robot Utility. Depending on when you
bought the library a copy may have been included, probably
an old one. As far as I know, the only changes of any
relevence to tape drives and libraries are the name
changes:
/dev/rmt* -> /dev/tape/tape*
/dev/nrmt* -> /dev/ntape/tape*
/dev/mc* -> /dev/changer/mc*
You should check with Legato to verify the version of
Networker you have is supported on V5. They may have
dependencies on names that required a change to work
on V5.
If you're using MRU V1.3 or earlier to control the media
changer, the older versions have a little trouble with
the new device naming in V5. I think these problems were
fixed by V1.4 or V1.5. In a V5 cluster, MRU can only be
used on the first node that accesses the changer. The
engineering group for MRU seems to be trying to figure this
problem out.
No responses, and then opened both hardware and software calls. By the
book, it is a supported device with no known issues. Guess I will discover
the real deal soon.
Any specific issues, events or experience performing a 4.X upgrade to 5.1
with the tl822 tape drive/jukebox. Minimum firmware version etc anyone has
had issues or success with doing a OS upgrade like this.
thanks
