Did you try an inventory of the slot its in and have it load the tape:
nsrjb -IE -S # ?    Did you try a library reset, then a reinventory:
nsrjb -H , then nsrjb -IE.

Does the tape name appear in the media database (or the
volume window)?   If none of these are yes and you know it has the data on
it you can scan it in with scanner command.

It could be tape is damaged though and the drive cannot read the label on
it.  I'd definitely try inventoring or loading it in another drive.
