David,

check the "Magstar 3494 Tape Library Operators Guide" GA32-0280-11

Chapter 6 , page 162, handles Volser Rages for Media Types


A volumes's media type is determined by using the following rules:

. The media type that the vision system returns is the first choice
. If the vision system cannot determine a volumes's media type, the volser
ranges are used.


You can set the Volser Ranges via the System Management interface of the
control program of the 3494.

Once set, all problems are gone ;-))

How does the 3494 determine which 'media type', e.g. 3590 J or K, a cart
is? Our 3494 is starting to eject tapes as they are inserted complaining
about unknown media type. These are tapes that have been in use for a
number of years and are being reinserted into the 3494 after coming back
from the offsite vault. Most of the time they are being correctly
recognized simply by reinserting them into the library another time. Our
non-IBM CE doesn't have a clue.
