A few things on the above.  I maintain both mpe and hpux and
also find hpux easier on the operations side.
 
For instance, backups.  For hpux, I currently use a 8GB
DDS drive which backs up 2 hpux servers, 2 workstations, and
an Apple server.  I can fit 3 days of the above on 1 tape.
If these were mpe systems, I would be mounting 15 tapes
and have 5 tape drives.  Not to mention that hpux has
very easy patch installation.  I can't even remember
having to reboot hpux for a patch.  With mpe, you
can take 3 hours to install one patch, due to rebooting
from the SLT, and then rebooting again!
 
Unrelated, someone earlier mentioned having trouble
with 1.3 GB DDS drives, and had replaced 3 in 3 years.
I've recently had to replace 4 in 3 days and one 2GB.
If you only have one tape drive, be sure you can read
previous tapes before the engineer leaves.  If you
have two drives, be sure the new drive makes tapes
the other can read.
