Gerhard,
I may be missing something, but I don't follow the logic in your
example about a single job wanting 8 drives being worse off if a drive is
flagged as unavailable.
If a job wants 8 drives, and 1 is broken, then surely that job isn't going
to run either way without a JCL change, is it?
The only difference I see is that with the broken drive being flagged
unavailable the job may fail, whereas if it tries to assign the broken
drive because it is flagged as available it will hang indefinitely.
Personally, I'd rather the job failed and freed up all 7 other tape drives
for use by other work if the drive is broken.
