8.13 Live Volume automatic restore
Live Volumes configured for automatic failover are also be configured for automatic restore by default (Figure
56). If Live Volume Automatic Failover has occurred and the impacted array and data center infrastructure is
subsequently recovered and brought back online, the Restore Automatically feature will repair Live Volumes
by replicating changed data back to the impacted site (leveraging the built-in minimal recopy feature) and then
bring the failed Live Volume back online as a secondary. The Restore Automatically feature is configured on a
per-Live-Volume basis and it is recommended to leave this enabled for the purposes of automation,
consistency, efficiency, and high availability of consistent data.
