Temporarily disable failover functionality

  • Last UpdatedJul 17, 2024

You can manually disable failover switching between the primary and secondary I/O nodes of an Access Name. A typical case for temporarily disabling failover is during the brief period when the components of an InTouch system are started and not yet ready. After the components have stabilized, you can restore failover switching.

To disable failover for an Access Name, you must have an Access Name configured for failover with a secondary I/O source.

You can manually disable failover switching by two methods:

  • Select the Disable Failover option from the Failover section.

  • Run a script that includes the IODisableFailover() function.
