Our CE had to change a setting on the 3590E tape drives to allow them to
write to the double length tapes.

        3590E normal tapes & long tapes ? ? ?  are you referring to "J"
tapes & "K" tapes ?  (that is all I know of...) J tapes are 3590-B1A tapes
which may be written to by 3590-E1A tape drives (a reformat is performed)
and K tapes are the 3590-E1A tapes from the start...  If this is the case,
yes, you can have both in an ATL that is loaded with 3590-E1A tape drives...
        OK, my ~technical~ term here... those little plastic do-ma-hickies
that are blue on "J" tapes, white on cleaning tapes and green on "K" tapes
have recesses in them that are in different locations and indicate to the
tape drive which type of media is in the drive...  You don't have to do
anything special...

        In our library IBM-3494 are 3490E tape-units. This library will
reach its limits for the number of cartridges.
        We think of replacing the 3490E normal tapes by long-tapes.
        Does TSM support a mix of different tapes?
        If so, is it necessary to make modification in e.i. hardware(3490E
modification?) or in TSM-settings.
        Are there pitfalls?
                                Kindest regards,
                                Fred de Rooij
