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:
v System firmware bringup (automatic)
v 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. It
cannot be disabled through a user selectable option.
If the service processor detects no heartbeats during system IPL (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 persists, the service processor
leaves the machine powered on, logs an error and offers menus to the user. If call-out
is enabled, the service processor calls to report the failure and displays the operating
system surveillance failure code on the operator panel.

Operating System Surveillance

Provides the service processor with a means to detect hang conditions, hardware or
software failures while the operating system is running. It also provides the operating
system with a means to detect a service processor failure by the lack of a return
heartbeat.
Operating system surveillance is not enabled by default allowing you to run operating
systems that do not support this service processor option.
Operating system surveillance can be enabled and disabled through:
v Service processor menus
v AIX service aids
Three parameters must be set for operating system surveillance:
v Surveillance enable/disable
v Surveillance interval
The maximum time the service processor should wait for a heartbeat from the
operating system before timeout.
v Surveillance delay
The length of time to wait from the time the operating system is started to when the
first heartbeat is expected.
