Kristian, I hate to ruin your day but....

All the files on the VOLUME SET which contained ldev 15 are most likely toast.
I invite those more knowledgable than me to jump in but, the way files are stored on 3000's is as follows:

A chunk of space is needed
The file manager looks for the disc that has the most space available and sticks it there.
Another chunk of space is needed for the same file
The file manager looks for the disc that has the most space available and sticks it there.
Repeat ad nauseum

This repeated search for the disc that is least full ends up sticking chunks of your file all over the volume set. The first time a
chunk gets stuck on ldev 15 you have a corrupted file.

The above monologue is a very simplified explanation of the procedure, I invite the swamis and gurus to correct, expand and
expound for the edification of all.

While it is likely some of your files don't use ldev 15 determining which ones don't would take an enormous amount of work in
my experience. Perhaps MPEX or Toolbox from Lund Performance solutions *might* be able to do the job, but I am *uncertain*
at best. (Even Eugene over at Vesoft is allergic to Kryptonite <g>)

I would suggest that you get out your latest full backup plus any partials, replace the drive, and bite the bullet. I hope that you
use the word ;DIRECTORY on your backups against the day you lose ldev 1. If you have more than the system volume set the
syntax is  ;DIRECTORY;ONVS=MPEXL_SYSTEM_VOLUME_SET,SET2,SET3,SETX

BTW, the only way to be sure that a tape drive really does work is to periodically restore a few files. A few dummy files restored
once a month would do the trick.

If you have a problem or any concerns please email me, I'm up late.
