Surveillance is a function in which the SP 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:
1. System firmware bringup (automatic)
Provides the SP 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 with a user
selectable option. If the SP 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 SP menus. If the fail condition repeats,
the SP leaves the machine powered on, logs an error and offers menus to
the user. If Call-out is enabled, the SP calls to report the failure and
displays the operating system surveillance failure code on the operator
panel.
2. Operating system run time (optional)
