Create Replicated Mirror Group Wizard: Configure mirror disk pairs

start of changeUse this page to provide configuration information for one or more mirror disk pairs to use for replication between sites. The wizard provides this page only when you have a storage type that requires you to configure the mirror disk pairs. end of change

You can configure mirror disk pairs only for the IBM® SAN Volume Controller (SVC) storage type.

start of changeMirror disk pairs represent the replication relationship between two disks or two volumes. This relationship must already be established at the storage level. One of the disks or volumes in the pair is on the primary site and the other disk or volume is on the secondary site.end of change
