Purpose

Provide additional information for message ID: SCF-8005-LC

Details

Predictive Self-Healing Article
Correctable errors within a SC chip have exceeded an acceptable threshold.

Type

Fault

  fault.chassis.SPARC-Enterprise.asic.sc.ce-l2tagcpu

Severity

Minor

Description

The number of correctable errors within the L2 cache tags of a SC chip has exceeded an acceptable threshold.

Automated Response

One of the L2 cache ways is deconfigured for all the CPU chips associated with this SC chip.

Impact

The domain is unaffected, except for the performance of the CPU chips.

Suggested Action for System Administrator

Schedule a repair action to replace the affected Field Replaceable Unit (FRU), the identity of which can be determined using fmdump -v -u EVENT_ID. Please consult the detail section of the knowledge article for additional information.

Details

The number of correctable errors within the L2 cache tags of a SC chip has exceeded an acceptable threshold.

One of the L2 cache ways is deconfigured for all the CPU chips associated with this SC chip.

The XSCF software preserves the L2 cache way deconfiguration across CPU resets.

Domains are unaffected, except for reduced performance.
The domain is expected to subscribe to this fault so that the domain can be
informed of the performance degradation introduced due to the fault.


The recommended service action for this event is to schedule the replacement of the affected FRU.

 

Step 1. Collect the fault message (use one of the following methods):


   Single-line fault message displayed on the XSCF console:

   Mar 20 21:45:39 san-ff2-21-0 fmd: SOURCE: sde, REV: 1.12, CSN: 7860000772  
   EVENT-ID: 5f09fb31-d70b-4553-9695-8feee671f407
   Refer to http://www.sun.com/msg/SCF-8005-LC for detailed information.


   Complete fault message using 'fmdump -m' on the XSCF console:

   MSG-ID: SCF-8005-LC, TYPE: Fault, VER: 1, SEVERITY: Minor
   EVENT-TIME: Tue Mar 20 21:45:39 UTC 2007
   PLATFORM: SPARC-Enterprise, CSN: 7860000772, HOSTNAME: san-ff2-21-0
   SOURCE: sde, REV: 1.12
   EVENT-ID: 5f09fb31-d70b-4553-9695-8feee671f407
   DESC: The number of correctable errors within the L2 cache tags of a SC chip has exceeded an acceptable threshold.
   Refer to http://www.sun.com/msg/SCF-8005-LC for more information.
   AUTO-RESPONSE: One of the L2 cache ways is deconfigured for all the CPU chips associated with this SC chip.
   IMPACT: The domain is unaffected, except for the performance of the CPU chips.
   REC-ACTION: Schedule a repair action to replace the affected Field Replaceable Unit (FRU),
   the identity of which can be determined using fmdump -v -u EVENT_ID.
   Please consult the detail section of the knowledge article for additional information.


Step 2. Collect the output from the 'fmdump -v -u EVENT_ID' command


        xscf> fmdump -v -u 5f09fb31-d70b-4553-9695-8feee671f407
