According to technical document http://support.veritas.com/docs/200962, it should be possible to force cataloging of a single tape from a set by going into the program options and clearing the checkbox labelled "Use storage media based catalogs". Unfortunately, however, it doesn't actually seem to work in version 10.0, although it did in version 9.x. I sure do hope that this will get fixed in some future build - it is a major nuisance to have no way to recatalog individual tapes if one tape in the set becomes unusable.
