To adjust the capacity of the external volume to create a pair:
1. Map the external volume (A) as an internal volume (B) of the local storage system. Set the
emulation type as same as that of the copy source volume (C).
2. Check the capacity of the internal volume (B) where the external volume (A) is mapped. If the
capacity of the mapped external volume (B) is not same as the copy source volume (C), use
the VLL function to create a CV that has the same capacity as the copy source volume (C)
out of the volume (B).
3. Create a pair.
