Harold,

I am not so sure. It seems different S/390 systems behave in different ways when (370) LPARS are configured..
... either that or there is an error in the ES/9000 functional characteristics.

From what I recall it has always tried to separate CPU model and architecture. i.e. changing the CPU model does not affect the operation of Hercules.
Perhaps we need to change that.
