This section shows the 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. Use both Unisphere for PowerMax and the symcli for the setup. You must also provide an SRDF connection from the SRDF/Metro storage systems to the SRDF/A leg. Repeat step 1 of the SRDF/Metro setup section, Step 1 – Create an SRDF connection between the storage systems, to create an SRDF connection between the storage systems.
The same SGs that are protected with SRDF/Metro for HA should also be considered for protection with Smart DR for DR purposes. In this step nothing is actually done except to identify the SG to be protected so that appropriate SRDF groups can be set for them in the next step.

Select Storage Groups (1) then the storage group to protect (2). Click Protect (3). Choose Setup remote replication using SRDF (4). Select the Remote Array ID (5) and the replication mode (6). Select Manual (7) and the SRDF Group Label created in the previous step (8). Enter the Remote Storage Group Name (9) and the Remote Service Level (10). Then review the SRDF Summary (11).

Repeat the setup steps for SRDF/A for all groups being protected by SRDF/A

This step is similar to step 2, only it is performed from Unisphere of the R2 (remote) storage system. Select Data Protection (1), SRDF Groups (2), Create SRDF Group (3). Select FC as the communication Protocol (4), Remote Array ID (5) and enter a SRDF Group Label (6). Enter the local SRDF Group Number (7) and Local Ports (8). Enter the Remote SRDF Group Number (9) and Remote Ports (10).
