Chapter 28. Interoperability between DS6000

and DS8000

In this chapter we show the interoperability between the Copy Services functions in the

DS6000 and the DS8000. It contains the following sections:

򐂰 DS6000 and DS8000 Copy Services interoperability

򐂰 Preparing the environment

򐂰 RMC: Establishing paths between DS6000 and DS8000

򐂰 Managing Metro Mirror or Global Copy pairs

򐂰 Managing DS6000 to DS8000 Global Mirror

򐂰 Managing DS6000 and DS8000 FlashCopy

Note: Remote Mirror and Copy (RMC) was formerly called Peer-to-Peer Remote Copy

(PPRC). All references to PPRC are interchangeable with RMC.
