Service Processor System Monitoring - Surveillance

Surveillance		is	a function		in which the Service	Processor	monitors the syste

odic	samplings		called	heartbeats.

Surveillance is available during two phases:

1.System firmware bringup (automatic)

2.Operating system runtime (optional)

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 power-on. cannot be disabled via a user selectable option.

Operating	System Surveillance:			Provides the Service Processor with a means
to detect hang conditions, hardware or software failures						while	the	opera
running. It also provides the					operating system with a means	to	detect		the
Processor		failure	by	the lack	of a return heartbeat.

Operating system surveillance is enabled by default. This is to allow the operating systems that do not support this Service Processor option.

Operating system surveillance can be enabled and disabled via:

Ÿ service processor Menus

Ÿservice processor Service Aids

Three parameters must be set for operating system surveillance:

1.Surveillance enable/disable

2.Surveillance interval

This is the maximum time in minutes the Service Processor should wait fo heartbeat from the operating system before timeout.
