Label the tape again.

Then you need one more writeable tape.

First of all you should have more (v)tapes. If you haven't set
runspercycle, then it's the same than dumpcycle. Also you have 14 tapes in
rotation. That's not a good idea. Maybe one dump doesn't fit on one tape
or you do a not planed backup. Then you have the problem that amanda don't
have a writable tape, because she had to overwrite one out of the
dumpcycle. Allways have more tapes than you require for your regular
backup plan. I suggest for your current configuration at least
tapecycle=17 tapes. Just to have some tapes left.

To configure splitting, you have at first to set runtapes>1 and then you
have to configure tape_splitsize for your (global) dumptype. Here I use
60GB vtapes and a splitsize of 3072M.
