Bob,
Don't bother. I can tell you from experience that it won't work, and
Tivoli support will tell you it isn't supported. BTW, export/import isn't
supported either, although it "may" work.
We are in the middle of a migration from AIX to HP (L2000 server). Tried
the same thing. The problem is apparently in the way TSM records data on
tape on AIX vs. on HP-UX.... TSM on HP-UX could not read the tape created
on AIX. I was able to export the database and import on HP-UX. But, like
you, we have a lot of node data on AIX (about 60TB). By my rough
calculations, (using DLT7000 drives) it would have taken more than six
months of exporting, 24x7, optimistically assuming a 5MB/sec throughput.
What we are now doing is keeping our old TSM and library online until the
"old" data expires.... which will be about a year. Then we'll
export/import any remaining archives. Luckily for us, we have the hardware
to do this.
Some other folks have suggested FTP'ing the database from AIX to
HP-UX....or 'tar'ing it... I didn't think of it, and now it's too late to
try, since we've been backing up on HP for several months. I also didn't
try the unloaddb/loaddb, but I suspect the same problem would exist.
Good Luck

Bob,
the issue of 'it won't work' doesn't preclude you from trying it! It
should work since the platforms are both UNIX (handling tape read/write
sim.).
Otherwise you'd unloaddb to a file and then move the file to the new
platform -- maybe preferable anyway to re-optimize the database...
