Purpose

This document discusses how to troubleshoot CPU sram, (l2sram, L3sram) and Memory Error(s) With Solaris[TM] Up

Troubleshooting Steps

Symptoms

• The customer may be reporting that the system crashed, rebooted, panic'ed, got UE errors, CE errors, or  went  down.  The system then came back up.

• Specifically the customer may be reporting:

  • The system may have unexpectedly rebooted and cause is unknown.

  • The system may have received UE, ECC errors, or recoverable memory errors.

  • The customer may say the system crashed, gone down, panic'ed, rebooted, or received CPU or memory errors

System Type and Configuration

• Sun Fire [TM] v1280/E2900 & Netra [TM] 1280/1290 (LighWeight8 Servers)

• Sun Fire[TM] 3800/4800/4810/6800/E4900/E6900 (Serengeti Servers)

• Solaris[TM] 8 (U5 and higher), Solaris[TM] 9, or Solaris[TM] 10

Assumptions:

• The appropriate Solaris domain is accessible.

• The system controller is also accessible.

Steps to Follow
Please validate that each troubleshooting step below is true for your environment. Each step will provide instructions or a link to the document for validating the step and taking corrective action as necessary. The steps are ordered in the most appropriate sequence to isolate the issue and identify the proper resolution. Please do not skip a step.
1. Verify Solaris[TM] is running and capture Solaris version.

• Perform a   uname -a   to confirm Solaris version and operational status

2. Verify this is not the issue described in Sun Alert 1000495.1

Sun Fire[TM] Systems Equipped With UltraSPARC IV+ Processor Modules Running Solaris 9 or Solaris 10 may Exhibit Unnecessary CPU Offlining and Solaris Panics

3. Verify that the appropriate diagnostic tools identify a FRU (Field Replaceable Unit) which requires replacement.

• The appropriate tools are:

  • For Solaris 8 & 9:

    • cediag: See Memory DIMM Replacement Management Tool - cediag FAQ (Doc ID 1003867.1)

  • Solaris 10:

    • fmdump: See Solaris[TM] 10 Operating System: Displaying the list of Fault Management Architecture (FMA) resources currently believed to be faulted (Doc ID 1018939.1)

• The following documents are available for reference:

  • Sun Enhanced Memory DIMM Replacement Policy (Doc ID 1010905.1)

4. Verify you can provide to Sun Support Services the recent error event data.

Run explorer to collect the proper data.

•   Oracle Explorer Data Collector - Product Information Center (Doc ID 1312847.1)

  
  
  • For more information on Explorer see: Oracle Services Tools Bundle Doc ID 1153444.1 and Oracle Services Tools Bundle Frequently Asked Questions (Doc ID 1287574.1)

Exception process for minimum data collection to begin diagnosis:

• It is always  Best Practices to provide Explorer output.  The complexity of the problems being resolved demands that Explorer data be available if at all possible.  If there might be a delay in having this data available and troubleshooting needs to begin immediately, at minimum provide the following output:

  • For Solaris 10: 

    • fmdump -v

• For Solaris 8 and 9 collect the following from Solaris:

  • /var/adm/messages 

  • prtdiag -v

5.  At this point, if you have validated that each troubleshooting step above is true for your environment, and the issue still exists, further troubleshooting is required.  Collaborate with Sun Support Services and provide the data suggested in the previous steps or if there is a question with any step of this troubleshooting process.
