DCU System Failover Properties

Table 8-19 DCU Auto and Manual Failover Properties

System Failover Property	Definition
Auto	Automated failover by Oracle ILOM for DCUs is enabled.
Manual	Automated failover by Oracle ILOM for DCUs is disabled. Note: When the Failover property is set to Manual, Oracle ILOM is prevented from performing system initiated DCUs failover. Automated failover of the Active-SP is always enabled. For M7-4 and M8-4 systems, the Active-SP is also the controlling SP for DCU0, therefore, DCU0 failover might still occur in the context of an Active-SP failover (typically initiated by component health). When Failover is set to Manual, Oracle ILOM will automatically log the following event in cases when a DCU failover attempt would have been made if the Failover property was set to Auto: `Failover on /System/DCUs/DCU_x was not initiated by system due to auto-failover disabled by user.`
