Dynamic Processor Resilience (DPR)

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, mark it for deconfiguration on the next system reboot, and generate a SERIOUS event. After the failed processor is deactivated, the LPMC monitor attempts to activate one of the inactive iCOD processors, 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.

	NOTE: Dynamic processor resilience is supported only if the inactive iCOD processors are configured for on-line activation.

V-Class Systems

A V-Class system has a slight variation from: L-2000, N-Class, Superdome, rp7410, and rp8400. This is because the V2500 and V2600 systems have dual processor boards. As a result, only the failing processor is deactivated, and after the system reboots, the pair of processors are deconfigured.

vPars

In a vPar environment, processors deactivated by the LPMC monitor must be manually replaced. See “LPMC Deactivations in vPars” for details.

Monarch Processors

See “Failed Monarch Processors” for details on replacing failed monarch processors.
