Backup Exec 2010 does not use Scratch Media, Jobs are in queued state

Hi,

on some of our Backup Exec Servers (newest Patch level) i have the issue that imported tapes (which were erased by another BE Installation before) won't be used by BE2010.

I moved the tapes to Scratch, but BE still wont use them to overwrite. The Media Protection Policy is set to partial. I already tried all the options but nothing helps.

As far as i know BE always has to overwrite Scratch Media? Or am i wrong with that?

Thanks in advance,

Dave
