There are a couple of ways to add Smart DR protection to existing SRDF/Metro group. The method described here will convert an SRDF/Metro group and add Smart DR protection to that. For other ways to set this up and additional guidance refer to Dell EMC PowerMax Family Product Guide in References.
In this step, we will add Smart DR to the SRDF/Metro storage group by utilizing the R1 side DR protection that we just set up, and we will select empty the RDF group from the R2 side (Metro_DR2) that we had created earlier.
Figure 20. SRDF/Metro Smart DR setup using conversion method
The following figure shows the progress of this task. As shown, the conversion process utilizes the remote RDF devices created in Step 3: Add Smart DR protection from the R1 side and creates pairings with the devices on the R2 system.
Figure 21. Smart DR conversion progress
The following figure shows the synchronization of the RDF group used for Smart DR setup for R2 side.
Figure 22. SRDF/Metro Smart DR group states
The following figure shows the devices used in the setup. As shown, the devices on the tertiary storage system used for Smart DR protection from the R1 and R2 sides are identical (devices 188-18F).
