Using the Service Processor and Service Director Features
The Service Processor and Service Director features protect users against
unnecessary system downtime by keeping support personnel (both internal and
external) aware of any unexpected changes in the system environment. In
combination, the two features provide a flexible solution to automated system
maintenance.
Service Processor
The Service Processor runs on its own power boundary and continually monitors
hardware attributes, the AIX Operating System, and the environmental conditions
within the system at all times. Any system failure which prevents the system from
coming back to an operational state (a fully functional AIX Operating System) is
reported by the Service Processor. The Service Processor is controlled by firmware
and does not require the AIX Operating System to be operational to perform its
tasks. If any system failures are detected, the Service Processor has the ability to
take pre-determined corrective actions. The methods of corrective actions are:
Ÿ
Surveillance
Ÿ
Call Home
Ÿ
AIX Operating System Monitoring
Surveillance is a function in which the Service Processor monitors the system
through heartbeat communication with the system firmware. During system startup,
the firmware surveillance monitor is automatically enabled to check for heartbeats
from the firmware. If a heartbeat is not detected within a default period, the Service
Processor cycles the system power and attempts to restart until the system either
restarts successfully, or a pre-determined retry threshold is reached. In the event the
Service Processor is unsuccessful in bringing the system on-line (or in the event that
the user asked to be alerted to any Service Processor assisted restarts), the system
can call home to report the error.
The Call Home function can be initialized to call either a service center telephone
number, a customer administration center, or a digital pager telephone number. The
Service Processor can be configured to stop at the first successful call to any of the
numbers listed, or can be configured to call every number provided. If connected to
the service center, the Service Processor transmits the relevant system information
(the system's serial number and model type) and Service Request Number (SRN). If
connected to a digital pager service, the Service Processor inputs a Customer Voice
Telephone Number defined by the customer. An established sequence of digits or
the telephone number to a phone near the failed system could be used to signal a
system administrator to a potential system failure.
