That was my point: you don't miss a thing.
You are fully redundant with CFs in each CPC.
And since the latest MQ update, all applications are capable of recovering their structures, so recovery is guaranteed in case of a CF failure.

That configuration is perfectly valid. You are merely missing some(but
not all) redundancy and recovery options.

Post by Mark A. BrooksThe essence of the matter is to ensure that the selected configuration
meets the availability objectives of the business services supported by
the sysplex. One must consider the service restoration objectives for
the business services in light of the potential failures that can occur
for a potential choice of configuration. There are many possibilities
and different installations will of course make different choices based
on their own business objectives. Choices of standalone CF, or
structure duplexing, and the like are really all talking about different
ways of solving the "failure isolation" issue (wherein we might be
concerned about the time to restore the business service if we
simultaneously lose the data in the CF along with the system that
produced that data). Each choice has its own advantages and
disadvantages; choose the one that's right for you.

However "option c", that means we don't have standalone CF and we do not
duplex CF structures is not proper one, is it?
