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 4-27.
