## About this task

To create a smart DR environment:

## Steps

1. Select the storage system.
2. Select Storage > Storage Groups.
3. Click Protect.
4. Click Setup High Availability with Disaster Recovery using SRDF/MetroDR and click NEXT.
5. Select a Metro R2 Array ID. To update the list of remote systems, click Scan.
6. Select Automatic or Manual for the Metro SRDF Group.
   If no suitable SRDF groups exist between the two arrays, this option is not available. The SRDF group is automatically resolved by creating an SRDF group. Automatic SRDF group creation with WLP support is available in the protection wizard when using SRDF, SRDF/Metro or SRDF/MetroDR technology for protecting a storage group. The Automatic SRDF Group option is selected by default. A new SRDF group is always created in automatic mode. An attempt to find or reuse an existing SRDF group is no longer made. The number of ports in the new SRDF group is based on the value in the settings dialog.
7. Optional: Clear the Establish SRDF Pairs checkbox.
8. Optional: Modify the Remote Storage Group Name.
9. Select a value for the Remote Service Level.
