Mixed tapes in a 3494 library

[mike_crawford]

Hi,

We are planning to use a mix of short and long length 3590 tapes in a single
3494 library.  Some storage pools will use the short tapes for a 20gb capacity,
others will use the long 40gb capacity.

Is it possible to have two types of scratch tapes existing in the same library,
or must we choose one length of tape for the scratch pool and staticly assign
tapes to the other stgpools?

Has anyone done this sort of thing, or have any thoughts on the subject?

Thanks,
Mike
