The SP can dial a pre-programmed telephone number in the event of an IPL
failure. The SP issues an error report with the last reported IPL status indicated
and any other available error information.
Ÿ
Update Operator Panel
The SP displays Operator Panel data on the ASCII terminal if a remote con-
nection is active.
Ÿ
Environmental Monitoring
Environmental Monitoring is now controlled by the SP instead of the base
system, with expanded error recording and reporting.
Ÿ
System Firmware Surveillance (Heartbeat Monitoring)
The SP will monitor and time the interval between system firmware heartbeats.
Ÿ
Responding to System Processor Commands
The SP will respond to any command issued by the system processor.
Runtime Phase
This phase includes the tasks that the SP performs during steady-state execution of
the operating system.
Ÿ
Environmental Monitoring
The SP monitors voltages, temperatures and fan speeds (on some servers).
Ÿ
Responding to System Processor Commands
The SP will respond to any command issued by the system processor.
Ÿ
Run-Time Surveillance (Heartbeat Monitoring)
If the device driver is installed and surveillance enabled, the SP will monitor the
system heartbeat. If the heartbeat times out, the SP places an outgoing call.
This is different from the Bringup Phase scenario where two reboot attempts are
made before placing an outgoing call.
