Is your hardware a tape drive or a tape drive and changer
mechanism. I'm getting mixed information from your
description. You are using tpchanger "chg-manual" which
should only be used with non-changer tape drives yet you
talk about "slot 5" as if it is an actual changer and
should use a tpchanger script other than chg-manual
(ex. chg-zd-mtx, chg-mtx, chg-scsi, ...).
You don't mention your version of amanda software.
Tape spanning was introduced with release 2.5.
Earlier releases would not support the feature.
Get your changer script functional, either chg-manual
or other scripts as appropriate. Tape spanning requires
it. Check out your ability to manipulate your "changer"
with the amanda command amtape.
