For operating system surveillance to work correctly, you must set these parameters:
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.
Surveillance does not take effect until the next time the operating system is started after the parameters
have been set.
If desired, you can initiate surveillance mode immediately from service aids. In addition to the previously
discussed options, another option allows you to select immediate surveillance, and rebooting of the system
is not necessarily required.
If operating system surveillance is enabled (and system firmware has passed control to the operating
system), and the service processor does not detect any heartbeats from the operating system, the service
processor assumes the system is hung and takes action according to the reboot/restart policy settings.
See “Service Processor Reboot/Restart Recovery” on page 392.
If surveillance is selected from the service processor menus that are only available at bootup, surveillance
is enabled by default as soon as the system boots. From service aids, the selection is optional.
Call-Out (Call-Home)
Note: Call-out is disabled on partitioned systems. The call-out function is handled by the Service Focal
Point application on the Hardware Management Console (HMC).
The service processor can call out (call-home) when it detects one of the following conditions:
v System firmware surveillance failure
v Operating system surveillance failure (if supported by operating system)
v Restarts
v Critical hardware failure
v Abnormal operating system termination
To enable the call-out feature, do the following:
1. Connect a modem to any serial port.
2. Set up the following using the service processor menus or diagnostic service aids:
v Enable call-out for the serial port where the modem is connected.
v Enter the modem configuration file name.
v Set up site-specific parameters (phone numbers for call-out, call-out policy, number of call-out
retries, and so on).
