This section describes the following steps involved in adding Smart DR protection to an existing SRDF/Metro configuration.
To add SRDF/Metro Smart DR to an existing SRDF/Metro environment, you will need to add an SRDF/A leg to both the R1 and the R2 sides of the SRDF/Metro environment. You must also provide an SRDF connection from the SRDF/Metro storage systems to the SRDF/A leg. Repeat Step 2: Create an SRDF connection between the storage systems from the SRDF/Metro HA Setup section of this document to create an SRDF connection between the storage systems.
