Well, appears that it now works correctly for me in TSM 5.1 -- it does
not unmount tape after the write completes... keeps it available in the
tape drive for any subsequent writes. No need to set KEEPMP=YES in the
client node definition.

Don't know what was wrong with TSM 4.2; I set up 5.1 with the identical
settings (I'd documented the step by step install and followed it) except
with some updated commands such as for library, drive, and path configs.

Oh well. Works great now. :) I'm liking what I see of TSM 5.1 so far.
