Hi;
We have z/vm v5r2 running suze v10 as a guest. Defined in ds8100
eckd mode fibber connection.
The question wee need to reconfigure the ds8100 to reclaim big portion of it
in oreder to allocate big
FBA disk to be used by linux. Can any body help in this issue??

I am not sure that he implied that but the FBA idea was FORCEd from VSE
because MVS/OS could not handle it. Removing FBA would make VSE more

FBA eliminated the conversion problem, and IMHO was faster access.

Which ones would those have been? Our 360/50 used punched mylar cards.
Any kind of disk that was available at the time would have been
physically too large to fit in the frame :-)

Why not FBA?
Oh, seems to me that some of the older high strength CPU's
used FBA

This had many large boards each containing many dozens of small memory
