Hi,
Other than the issue of wanting the last system that goes down to be
the first system IPLed into the sysplex (so as to avoid the operator I,J,R
prompt), I'm not aware of any technical reason that would require a
particular IPL order. In particular, I don't understand why there would be
any motivation to "ensure structures built in the coupling facility will
always be built by a particular LPAR". To me, the very notion is anathema.
We could never deliver on the promise of high availability if there was a
dependency that one particular system had to be the one to create the CF
structures. It also suggests that one would need to wait for all
applications that create CF structures to do their allocations before any
other system could be IPLed into the sysplex.
Does someone have an example of a CF Structure that would demand the
sort of enforcement that is being suggested?
