Service Processor System Monitoring - Surveillance
Surveillance is a function in which the service processor monitors the system, and the system monitors the service processor. This monitoring is accomplished by periodic samplings called heartbeats
Surveillance is available during two phases:
vSystem firmware
vOperating system run time (optional)
System Firmware Surveillance
System firmware surveillance provides the service processor with a means to detect boot failures while the system firmware is running.
System firmware surveillance is automatically enabled during system
If the service processor detects no heartbeats during system boot (for 7 minutes), it cycles the system power to attempt a reboot. The maximum number of retries is set from the service processor menus. If the fail condition repeats, the service processor leaves the machine powered on, logs an error, and displays menus to the user. If
Operating System Surveillance
The operating system surveillance provides the service processor with a means to detect hang conditions, as well as hardware or software failures, while the operating system is running. It also provides the operating system with a means to detect service processor failure caused by the lack of a return heartbeat.
Operating system surveillance is enabled by default, allowing the user to run operating systems that do not support this service processor option.
You can also use Service Processor Menus and Service Processor Service Aid to enable or disable operating system surveillance.
For operating system surveillance to work correctly, you must set the following parameters:
vSurveillance enable/disable
vSurveillance interval
