The source-volume S have been snapmirrored and the Destination volume is "D". Now, after the snapmirror relationship got broken off(the relationship has not been deleted), D becomes RW.
At this point, i believe volume "S", and volume "D" are two separated volumes.
1. will "D" has any performance impact on the source storage? 2. Will it cause any issues to use D in the status of "broken-off"? 3. If the source volume has multiple SM relationships, then how much performance impact will multiple replications have on the source storage?
