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. Any | system failure which prevents | the | system | from | returning | to | ||
an operational state (a fully | functional AIX operating system) is | reported | by | th | |||||
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 an | ||||||||
system failures are detected, the Service Processor can take predetermined |
| ||||||||
corrective | actions. The | methods | of corrective actions | are: |

ŸSurveillance
ŸCall Home
ŸAIX Operating System Monitoring
Surveillance is a function in which the Service Processor monitors the system through heartbeat communication with the systemheartbeatfirmwareis. Thea
periodic signal that the firmware can monitor. 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 attempts to reboot the system until the system either restarts success
