Subject: 3480 tape label problem

We are running VM/CMS 5.6 370 mode on an IBM 3084-Q. We just recently acquired
some 3480 tape drives. I just signed out a new 3480 tape from our scratch pool.
We use VMTAPE to facilitate tape mount requests.

A 3480 tape was mounted, but after placing some files on it in CMS tape format,
I am unable to get the TAPE SCAN command to work. I can see the files on the
tape via Dave Elbon's tapemap utility and Ditto, but TAPE SCAN objects and
won't provide any info about the files on the tape. Does anyone know what is
wrong here? Thanks? A copy of the console where I dumped the files to the new
tape appears below including a display of the label, which I just rewrote.
