The LPMC monitor, within the Support Tools Manager
(STM) diagnostics, generates Information events for all cache errors
that are detected. After three errors (Threshold) have been detected
on a processor in 1440 minutes, or a 24-hour period of time (Period),
the monitor deactivates that particular processor, marks it for deconfiguration
on the next system reboot, and generates a SERIOUS event. After the
failed processor is deactivated, the LPMC monitor attempts to activate
one of the inactive Instant Capacity cores, if any are available.
This method ensures the processing power of the system is unchanged.
A default value of “three” is assigned
to Threshold, except for the PCX-W+ family of processors, which has
a value of “five” assigned. The default value assigned
to a Period is 1440 minutes, or 24 hours, in all possible processor
configurations.
An inactive processor under warranty or support
automatically replaces a failed processor. HP also services and replaces
any failed processor.
