Zusammenfassung:An information management system implements a method for determining whether to initiate a failover of a storage manager in the system. Nodes in the system may be assigned as monitoring nodes configured to communicate with a storage manager. Furthermore, each monitoring node may be configured to transmit a status inquiry message to each other monitoring node, and each monitoring node may receive a status inquiry message from each other monitoring node. Each monitoring node may also generate a session message comprising status information, and a plurality of failover nodes may receive the generated session messages. A failover node may then determine whether a failover condition has occurred by applying a plurality of failover rules to the status information of the transmitted session message. Where the failover node determines that a failover condition has occurred, the failover node may activate an offline storage manager to replace the active storage manager.
