MTBF Information:
The MTBF (Mean-Time-Between-Failures) information of a component can be
viewed or cleared (initialized). Your server manages the MTBF of each
component. If a fault occurs in a component, the module calculates the MTBF
of the component again. If the calculated value is lower than the pre-defined
threshold, the system performs one of the following predefined three functions:
!
Use Threshold: MTBF is calculated when a fault occurs. If calculated
MTBF is below the set threshold value, the device is stopped.
!
Never Restart: The device is stopped whenever a fault occurs.
!
Always Restart: The device is rebooted whenever a fault occurs.
Note:
A disabled component with the MTBF lower than the threshold
can be forcibly enabled by clearing the MTBF.
Procedure:
To clear the MTBF information of the PCI module, press the MTBF button
displayed in the Maintenance screen.
