Use OS-Defined restart policy?: The Use OS-Defined restart policy default setting is YES. This causes the SP to refer to the OS Automatic Restart Policy setting and take action, the same action the OS would take if it could have responded to the problem causing the restart. When this setting is NO, or if the OS did not set a policy, the Service Processor refers to Enable supplemental restart policy for its action. Enable Supplemental Restart Policy?: The default setting is NO. If set to YES, the Service Processor restarts the system when the system loses control as detected by the Service Processor surveillance, and either: 1. The Use OS-Defined restart policy is set to NO OR 2. The Use OS-Defined restart policy is set to YES and the operating system has NO automatic restart policy. Refer to "Service Processor Reboot/Restart Recovery" on page B-27.
