Today, when a SM relationship is broken off, SRM wont run a recovery group related to this relationship. IHAC asking if there is a future change in this functionality in a way that SRM will warn but run the recovery group anyway.
. SRM itself is unaware of he status of snapmirror relationships. When SRM requiest the SRA to break a relatinoship, if that relationship is already broken I believe the SRA ignores this and reports back that the relationship is ready for SRM.
