Subject: Re: Coupling Facility > 2GB of central
>Can I
have more than 2GB defined as central storage on my ICF, even if the
z/OS lpars are still running 31 bit mode.
No, not yet.
There is the concept of control/non-control storage.
CF-Speak for Central/Expanded.
I don't believe IBM has come out with 64-bit CF's, yet.
If they have, I missed the announcement.
Also, the mode you are using in z/OS is independent of the mode you use
in the CF.
