a function

in which the Service

the

Service Processor. This

monitoring

is accomplished by

odic

samplings

called

heartbeats.

 

 

Surveillance is available during two phases:

1.System firmware bringup (automatic)

2.Operating system runtime (optional)

System Firmware

System firmware surveillance is automatically enabled during system power-on. cannot be disabled via a user selectable option.

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.
