High Availability (HA) allows users to run more than one Itential Platform instance in a data center. For example, you may have a data center on the East Coast with 6 active instances of Itential Platform running virtually. Meanwhile, you have a back-up on the West Coast that contains 6 instances of Itential Platform running in a passive state for disaster recovery. If task execution fails in an HA Itential Platform environment, you can determine the specific Itential Platform server that attempted to execute the task by referencing the Server ID of the failed task.
Each Itential Platform server in an HA environment has a unique Server ID property that is defined in one of two ways:
- Manually via the
serverNameproperty of theproperties.jsonfile located in the Itential Platform installation directory. - Automatically by combining the MAC address and Itential Platform port values and hashing them.
When a server attempts to execute a task, its Server ID property is added to the Task Details panel of that task. Be sure there are no connection issues affecting the server identified by the Server ID property of a failed task.
