v Follow the suggested actions in the order in which they are listed in the Action column until the problem is solved. v See Chapter 3, "Parts listing, Type 8864," on page 23 to determine which components are customer replaceable units (CRU) and which components are field replaceable units (FRU). v If an action step is preceded by "(Trained service technician only)", that step must be performed only by a trained service technician. Error message Action PCI to PCI Bridge Discard Timer Error Chassis#=X Slot#=Y Bus#=Z Dev.ID=0xSSSS Vend.ID=0xTTTT Status=0xUUUU DevFun#=0xVV 1. If the slot number is greater than 0, complete the following steps: a. Reseat the adapter. b. Replace the adapter. 2. If the slot number is 0, replace the PCI board. SMI handler reporting Memory Mirroring Failover 1. Reseat the DIMM or memory card. Occurred. Running from mirrored image. Note: This message immediately follows an uncorrectable memory error. 2. If the DIMM was disabled by the user, run the Configuration/Setup Utility program and enable the DIMM. 3. Replace the DIMM or memory card. 4. If the DIMM was disabled by the user, run the Configuration/Setup Utility program and enable the DIMM. SMI handler reporting Processor Event: Unrecoverable error. Chassis Number = X. Processor ID = Y. (Trained service technician only) Replace the microprocessor. Solving SCSI problems Note: This section also applies to Serial Attached SCSI (SAS) problems. For any SCSI error message, one or more of the following devices might be causing the problem: v A failing SCSI device (adapter, drive, or controller) v An incorrect SCSI termination jumper setting v Duplicate SCSI IDs in the same SCSI chain v A missing or incorrectly installed SCSI terminator v A defective SCSI terminator v An incorrectly installed cable v A defective cable For any SCSI error message, follow these suggested actions in the order in which they are listed until the problem is solved: 1. Make sure that external SCSI devices are turned on before you turn on the server. 2. Make sure that the cables for all external SCSI devices are connected correctly. 3. If an external SCSI device is attached, make sure that the external SCSI termination is set to automatic. 4. Make sure that the last device in each SCSI chain is terminated correctly. 5. Make sure that the SCSI devices are configured correctly. 154 IBM System x3850 Type 8864: Problem Determination and Service Guide

actions
in
the
order
in
which
they
are
listed
until
the
