failure, the service processor can initiate a reboot/restart process based on the settings in the ServiceProcessor Reboot/Restart Policy Setup Menu and the OS automatic restart settings (see the operatingsystem documentation).If you are using the AIX operating system, the menu item under SMIT for setting the restart policy isAutomatically Reboot After Crash. The default is false. When the setting is true, and if the serviceprocessor parameter ″Use OS-Defined Restart Policy″ is yes (the default), the service processor takesover for AIX to reboot/restart after a hardware or surveillance failure.Service Processor Reboot/Restart Policy ControlsThe operating system’s automatic restart policy (see operating system documentation) indicates theoperating system response to a system crash. The service processor can be instructed to refer to thatpolicy by the Use OS-Defined Restart Policy setup menu.If the operating system has no automatic restart policy, or if it is disabled, then the serviceprocessor-restart policy can be controlled from the service processor menus. Use the EnableSupplemental Restart Policy selection.Use OS-Defined restart policy - The default setting is no. If set to yes on a full system partition, thiscauses the service processor to refer to the OS Automatic Restart Policy setting and take action (the sameaction the operating system would take if it could have responded to the problem causing the restart).When this setting is no, or if the operating system did not set a policy, the service processor refers toenable supplemental restart policy for its action.This setting is ignored on a partitioned system.Enable supplemental restart policy - The default setting is Yes. When set to yes on a full systempartition, the service processor restarts the server when the operating system loses control and either:v The Use OS-Defined restart policy is set to No.ORv The Use OS-Defined restart policy is set to Yes and the operating system has no automatic restartpolicy.If set to Yes on a partitioned system, the service processor restarts the system when the system losescontrol and it is detected by service processor surveillance.The following table describes the relationship among the operating system and service processor restartcontrols in a full system partition.OS Automaticreboot/restartafter crash settingService processor to useOS-Definedrestart policy?Service Processor Enablesupplemental restartpolicy?System responseNone No 1 NoNone No 1 Yes1 RestartsNone Yes NoNone Yes Yes1 RestartsFalse 2 No 1 NoFalse 2 No 1 Yes1 RestartsFalse 2 Yes NoFalse 2 Yes Yes1True No 1 NoTrue No 1 Yes1 Restarts40 Eserver pSeries 655 User’s Guide
