Servicing Pcie Cards And Pcie Card Filler Panels - Oracle Sun Server X4-4 Service Manual

126 Sun May 21 00:53:56 2000 DIMM Service Required Memory P0/MR0/D6 (CPU
Memory Riser 0 DIMM 6)
A failure has occurred during Memory Reference Code (MRC) DIMM module
training. (Probability:33, UUID:9014a82c-7bf9-ee96-b61b-9c7ccedc9aed, Part
Number:001-0003-01,HMT42GR7AFR4A-PB, Serial Number:00AD01132129B11E9E,
Reference Document:http://support.oracle.com/msg/SPX86A-8004-67)
In this scenario, the DIMM in D6 shows as failed at 00:53:56, and that failure is subsequently
followed by a reported failure of the DIMM in D9, which failed at 00:53:57. Both DIMMs are
on the same memory riser card (P0/MR0). Each DIMM is on a separate channel, but both are
linked to the same memory buffer ASIC. Additionally, all of the DIMMs in both channels might
have been disabled by the system. This scenario could be an instance of a multi-DIMM failure
state.
How to Troubleshoot a Multi-DIMM Failure State
To troubleshoot this issue, replace only the DIMM that logged the initial failure and return the
server to operation to see if the multi-DIMM failure state persists. If a multi-DIMM failure state
had occurred, replacing only the DIMM that failed initially would rectify the fault state of the
initial DIMMs and the subsequent DIMMs. If the failures persists, the issue could be with the
DIMMs or with the memory riser card.
