Chassis Code to Customer Replaceable Unit (CRU) Decode



This is a guide to identify failing CRU's from the Error Chassis Logs. The guide includes the following information:

Accessing Error Chassis Logs

Execute the following steps to access the Error Chassis Logs.

  1. At the system console prompt, type CTRL B (this will bring up the gsp login screen)

  2. Type in the Service Processor Login and Password (this will give you a GSP prompt)

  3. At the prompt,

    GSP>, type SL (this will take you to the support logs)

  4. At the prompt,

    Which buffer are you interested in: Incoming, Error, Current boot, Last boot? (I/A/E/C/L), type E (for error logs)

  5. At the prompt,

    Do you want to set up filter options on this buffer? (Y/[N]), type N

  6. At this point, the most recent Error Log Entry (Log Entry #0) will be displayed. A carriage return after this will display the next log entry. Type Q to stop displaying the log entries.

  7. At the prompt,

    GSP>, type CO to return to the console

Key CRU Identification Fields for Error Chassis Logs

The following fields (bold in the sample error log entry) are useful for CRU identification.
Source: What major part of the system the alert is referring to (i.e., platform, memory, processor, etc.).
Source Detail: What sub-part of the system the alert is referring to (i.e., cabinet fan, DIMM, high voltage DC power, etc.).
Problem Detail: Specific problem information (i.e, power off, functional failure, etc.).

Cross-Referencing Chassis Log Errors to A400/A500 CRU's 

Use the following table to identify the failing CRU from the Chassis Log information.

  1. Read the Chassis Log entry.

  2. Match the SOURCE, SOURCE DETAIL, SOURCE ID, and PROBLEM DETAIL values found in the Chassis Log entry with the appropriate values in the table.

  3. Read the table from left to right.
