Flashcopy support in DS8K when using Metro mirror dual leg

Mirrored volumes between two DS8K support and keep the mirror intact when using Flashcopy.

We have functions in example DSS like:
FCNOCOPY FASTREPLICATION(REQUIRED )
FCTOPPRCPRIMARY(PRESMIRREQ )

SW functions in DB2 have made utilities that uses the mentioned functionality.

But!
None of it works when using GDPS/PPRC Metro mirror dual leg(Mirroring in two directions from primary)

    As you can see in case TS008420630 this also conflicts with the DB2 utilities which invokes ADRDSSU with the COPY parameter FCTOPPRCPRIMARY(PRESMIRREQ ). It would be much easier and without challenges for us users if the subsystems just supported the functionality by default.
    Any updates regarding progress for this RFE?

    Important to preserve mirror on both legs certainly. This is a vote in favor of the suggestion.
