Shared Disk, Passive – Active Failovers on Fault-Tolerant Agent

This scenario is almost the same as Scenario: Shared disk, passive–active failover on a master domain manager, but there are no additional steps to perform on the DB2® and WebSphere® Application Server and the start_tws.sh and top_tws.sh scripts run just the link/unlink and start or stop commands.
