Failover is a process by which a PASSIVE system (B) is made as ACTIVE in the event of a irrecoverable failure of the ACTIVE system (A). During a Failover operation, the PASSIVE system (B) will rollback to the latest available snapshot – snap group across all volumes. After a failover the PASSIVE box (B) will become ACTIVE. If volume is of type SAN, the iSCSI initiator can connect to the volumes in the Consistency group and start performing I/Os. NAS volumes will be mounted and shares will be made available after a Failover from the newly ACTIVE system (B).
