Configure Live Volume Automatic Failover and Restore
You can enable Storage Center Automatic Failover and Automatic Restore from the vSphere Client Plugin on Live Volumes that meet
certain criteria. When Automatic Failover is enabled, the secondary Live Volume will automatically be promoted to primary in the event of a
failure. After the primary Live Volume comes back online, Automatic Restore, configured by default, restores the Live Volume relationship.
Prerequisites

• Synchronous
• High Availability
• Protected
Steps
