GDPS/MGM does not handle all status combination

In a GDPS/MGM environment there are situations where the primary and secondary GM status combination is not handled properly. For example, after a hardware failure on an intermediate disk subsystem, if the B volumes are set to SIMPLEX due to a CST operation, whereas the C volumes are left SECONDARY SUSP, then GDASD INIT terminates with error because this combination status is not accepted. An other case is when after moving from ABC to AC, the B disk subsystem is replaced or the volumes in it are set to SIMPLEX. In this scenario going back from AC to ABC requires a full copy of both the PPRC and the GM. Having a proper handling of the combination could allow the GDPS/GM procedure to copy the data from C (PRIMARY SUSP) to B (SIMPLEX) and then go back to from ACB to ABC with an Incremental resync. So, both GDASD INIT and the PROCEDURE statement should handle all possible combination to avoid full copy or even the inability to reestablish the MGM environment.
