Hi Sam
Oups !
I'm afraid the only possible split you can have is at filespace level
when exporting a node from OS/390 to AIX. Do as many export as filespace
for a particular node. The main drawback is that you will creep over your
tapes more than one time !
You can also choose to export only HSM-ed data
adsm > export node TOTO FILEA=SPacemanaged FILESPACE=\\TOTO\C$
Godd luck
