All,

Though you may find this useful/interesting.  We discovered yesterday that
there is a problem with 3.7.3.0.  APAR #IC27348 has been generated and
development is currently working on the problem.

The Problem : Data cannot be appended to a tape after an initial write.
There is some sort of problem after the tape is rewound that prevents TSM
from being able to locate the end of data on the tape.

Temporary Workaround : Keep the tapes mounted by setting the mountr value to
9999.  If the tape is not rewound then there is no problem adding data. (I
know this is impractical in most situations)  The other solution is to roll
your DB back to 3.7.2.0 and go from there (Also not a real great option.)

I'll let you guys (and gals :)) know when we know more.

Thanks!
Mooney
