Using an external volume as an S-VOL to copy data

1. Use Universal Volume Manager to map the external volume (A) to an internal volume (B) of the local storage system. You will use volume (B) as the S-VOL of a copy pair.
2. Check the capacity of internal volume (B) to which external volume (A) is mapped. If the capacity of internal volume (B) is different than the copy source volume (C), create a CV that has the same capacity as the copy source volume (C).
3. Create the copy pair using copy source volume (C) as the P-VOL and volume (B) as the S-VOL. This configuration makes a copy of the source volume on external volume (A).
