Details

The Message ID: SPSUN4V-8000-CQ indicates diagnosis has determined that a memory DIMM is faulty as a result of exceeding the threshold for correctable memory errors. Memory pages associated with the correctable errors have been retired and no data has been lost.

Use the command fmdump -v -u <EVENT_ID> with the <EVENT_ID> from the console message to locate the faulty DIMM. Depending on the platform the fault was diagnosed on, the location of the faulty DIMM will be displayed in one of two ways. For some platforms, the output of fmdump will appear as follows:

fmdump -v -u f92e9fbe-735e-c218-cf87-9e1720a28004
TIME                 UUID                                 SUNW-MSG-ID

        rsrc: mem:///component=MB/CMP0/CH0:R0/D0/J0601

In this example, the DIMM location is:

MB/CMP0/CH0:R0/D0/J0601

The alternate format for the output of fmdump for this fault is:

fmdump -v -u  b277ec2e-55b6-ea0b-8c88-aaff3ba7fa9a

       Location: MB/CMP0/BR1: CH1/D0/J1601

In this example the FRU includes a part number field:

part=371-2143-01 Rev01

This is the part number of the faulty DIMM. The location of the DIMM in this example is specified in the “Location” field:

MB/CMP0/BR1: CH1/D0/J1601

Refer to the Service Manual or the Service Label attached to the server chassis to find the physical location of the DIMM. Some platforms also provide fault indicators for individual DIMMs to validate the location. Once the DIMM has been replaced, use the Service Manual for instructions on clearing the fault condition and validating the repair action.

NOTE - The server Product Notes may contain updated service procedures. The latest version of the Service Manual and Product Notes are available at the Sun Documentation Center.
