Thanks again for Your help, and at the same time I have to apologize
for not making myself clear. I forgot to mention I'm not using z/VM
for the installation (don't ask why... just following orders:), just
Linux on plain LPAR. So I suppose that if something's wrong with
mainframe configuration, it's in the HMC; but I'm not even sure that I
can share the OSA this way. Some people I asked before said yes.

Regards,
Blazej
