Attention: Selecting fast IPL results in several diagnostic tests being skipped and a shorter memorytest being run.Service Processor Reboot/Restart RecoveryReboot describes bringing the system hardware back up; for example, from a system reset or power-on.The boot process ends when control passes to the operating system process.Restart describes activating the operating system after the system hardware is reinitialized. Restart mustfollow a successful reboot.Boot (IPL) SpeedWhen the system enters reboot recovery, slow IPL is automatically started, which gives the POST anopportunity to locate and report any problems that might otherwise be unreported.Failure During Boot ProcessDuring the boot process, either initially after system power-on or upon reboot after a system failure, theservice processor monitors the boot progress. If progress stops, the service processor can reinitiate theboot process (reboot) if enabled to do so. The service processor can re-attempt this process according tothe number of retries selected in the Reboot/Restart Policy Setup Menu.Failure During Normal System OperationWhen the boot process completes and control transfers to the operating system (OS), the serviceprocessor can monitor operating system activity (see the Set Surveillance Parameters option in theSERVICE PROCESSOR SETUP MENU). If OS activity stops due to a hardware- or software-inducedfailure, 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.250 EserverpSeries 615 Service Guide
