I had a similar problem, tape changing to unavailable, a few months back.  In 
my case, it was a problem with how the tape was identified.  The Library, an 
XLS, had it as "123456".  TMS has "123456" as a scratch tape and also had tape 
"123456L4" as the tape I wanted.  I had to check "123456" out of TMS and then 
check it back in as "123456L4".  This may not be the cause of your problem, but 
it is something to check.
