PCI split completion SERR in multi-node servers - Servers

Troubleshooting


Problem

When the primary node contains a ServeRAID 8i adapter, and there is no ServeRAID 8i in the secondary node, then the following error may be seen: 32 WARN SERVPROC Software NMI 33 INFO SERVPROC SMI Handler reporting SERR PCI Event: Received split completion error message on primary bridge Slot-Number = 0. Bus-Number = 15. Device ID = 0x2a1. VendorID 34 ERR SERVPROC System Error PCI Bus 35 ERR SERVPROC SMI handler has reported a PCI SERR Note: Symptoms may be seen when running any Linux based operating system, including VMware, or when loading ServerGuide, running UpdateXpress, and after updating system firmware.

Resolving The Problem

Source

RETAIN tip: H184844

Symptom

When the primary node contains a ServeRAID 8i adapter, and there is no ServeRAID 8i in the secondary node, then the following error may be seen:

32 WARN SERVPROC Software NMI
33 INFO SERVPROC SMI Handler reporting SERR PCI Event: Received split completion error message on primary bridge Slot-Number = 0. Bus-Number = 15. Device ID = 0x2a1. VendorID
34 ERR SERVPROC System Error PCI Bus
35 ERR SERVPROC SMI handler has reported a PCI SERR

Note: Symptoms may be seen when running any Linux based operating system, including VMware, or when loading ServerGuide, running UpdateXpress, and after updating system firmware.

Affected configurations

The system may be any of the following IBM servers:

  • System x3950 E, type 8874, any model
  • System x3950 E, type 8879, any model
  • System x3950, type 8872, any model
  • System x3950, type 8878, any model
  • xSeries 460, type 8872, any model
  • xSeries MXE-460, type 8874, any model

The system is configured with one or more of the following IBM Options:

  • ServeRAID-8i Controller, Option 13N2227, replacement part number 13N2233

This tip is not software specific.

Solution

None. This is a design limitation.

Workaround

Check that the on-board SAS controller is disabled in any node that does not have a ServeRAID 8i controller when there is a ServeRAID 8i in the primary node. This check should be performed after updating system firmware or running the Server Guide CD.

Additional information

Updating firmware in a secondary node may force the on-board SAS controller to an enabled state by default. Note that running the Server Guide may update the ServeRAID 8i controller to a minimum firmware level as part of the normal operation. The on-board SAS controller should be disabled in a secondary node if there is a ServeRAID 8i in the primary node to avoid the symptoms. For additional workarounds with Server Guide, please refer to the Server Guide User's Guide, Chapter 5 "Limitations."
