Systems
When you copy data between different storage systems, the copy operations
are usually different depending on the storage system which you use.
If you install Universal Volume Manager, you can perform the following copy
operations in the same way as when you copy data between volumes in the
USP V/VM storage system.
• To copy data between a volume in the USP V/VM storage system and a
volume in an external storage system.
• To copy data between a volume in an external storage system and a
volume in another external storage system.
