Abstract
In one aspect, minimization of recovery time after a high availability (HA) event in a storage system is provided. An aspect includes creating, during an active replication session, mini replication session MOM objects from replication session-related configuration information of the active replication session, and creating mini volume objects for volumes of the active replication session, Upon determining an occurrence of the HA corresponding to the data module, an aspect includes reconfiguring the mini replication session MOM objects and the mini volume objects prior to activation of the data module and prior to enabling input/output (TO) servicing by the data module. An aspect further includes performing non-replication IO-related configuration for the data module and, upon completion of the non-replication IO-related configuration, enabling the IO servicing by the data module. Subsequent to enabling the IO servicing by the data module, an aspect also includes loading and reconstructing remaining replication session-related configuration.
