System and method for failover of iSCSI target portal groups in a cluster environment

摘要

A system and method for the failover of iSCSI target portal groups (TPGs) is provided. Each network portal within a storage system is associated with a network portal data structure identifying a destination storage system in the event of failover/takeover operation. A management module ensures that all network portals associated with a target portal group have the same destination as a failover storage system. During a failover operation, all network portals within a TPG failover to the same destination storage system.
