The inability to expand volumes with FlashCopy mappings ALSO prohibits expanding volumes in Global Mirror w/Change Volumes (GMCV) relationships, since the Change Volumes use FlashCopy mappings.
This forces a complex, error-prone process of changing the relationship to regular Global Mirror (including first removing it from the Consistency Group), expanding the Source/Target volumes, expanding the Change Volumes, changing back from GM to GMCV, and adding back into the Consistency Group. This can be as many as 21 steps (if you include checking consistency and modifying FlashCopy Mapping clean rates).
