SRDF recovery operations
This section describes recovery operations in 2-site SRDF configurations.
Planned failover (SRDF/S)
A planned failover moves production applications from the primary site to the
secondary site in order to test the recovery solution, upgrade or perform maintenance
at the primary site.
