Is the data in an error state ?
For  example, if a scratch tape is mounted and the volser can't be verified
(read) the tape will be marked private to prevent further access.  This
sounds like it could be your problem... try to read the label on the tape...

"checkout libvol LIB VOLSER checklabel=yes"
and see what you get...
