# View SRDF groups

SRDF groups provide a collective data transfer path linking volumes of two separate storage systems.

## Prerequisites

See Roles and associated permissions to determine the user roles that can perform this task.

## About this task

The SRDF SG list displays a notification when a capacity mismatch exists between R1 and R2 devices. Mismatch can be R1 > R2 or R1 < R2.

See Dell SRDF Introduction for an overview of SRDF.

Note: Attempting to perform any action from the SRDF Group list view on a VASA Replication Group (where Type indicates VASA) is blocked. A dialog is displayed indicating that management of VASA Replication Groups can only be done using the vVol dashboard. The Volumes Count column displays "-" for VASA Replication Groups. Non-VASA SRDF Groups continue to display their volume count.

## Steps

1. Select the storage system.
2. Select DATA PROTECTION > SRDF Groups to open the SRDF groups list view.

   Use the SRDF groups list view to display and manage SRDF groups.
