CMMVC7158E: The change volume could
not be associated because the Metro Mirror or Global Mirror relationship
has a volume on this
cluster that is already involved in the maximum number of FlashCopy
mappings.
Explanation
The change volume cannot cause another volume to exceed
the number of FlashCopy mappings allowed.
User Response
Reduce the number of FlashCopy mappings in the
volume that has reached its maximum.
