Checking and Clearing the MTBF
The ft server manages Mean Time Between Failures (MTBF) of each component. If a fault occurs in a
component, the ft server calculates the MTBF of the component again. If the calculated value is lower than the
defined threshold, the ft server disables the component to be used.
A disabled component with the MTBF lower than the threshold can be forcibly enabled by clearing the MTBF.
Important Before clearing MTBF and forcedly enable the component, contact your
maintenance personnel for the forced use of such a component.
