Purpose

Provide additional information for message ID: M10-device.pump.tooslow_llc

Fujitsu fault codes:

01911220, 01919220

Details

Type

Hardware Fault

   device.pump.tooslow_llc

Severity

Minor

Description

Fault due to the rotation speed of a LLC pump being either lower than its predefined threshold, or due to a pump being stopped completely.

Note that, under certain conditions, it is possible to generate this fault when a power-off is attempted and an external USB-powered device is connected to either the front or rear USB port e.g. a USB DVD drive. If this is the case, remove the external USB device, clear the fault and retry the power-off operation. See document CMUL Faulted with Power Issues ( Error Messages 01910d00, 01919220, 018f0001 ) (Doc ID 1904125.1).

The recommended DVD drive and AC adapter is Oracle option 7106761 External USB DVD drive with AC adapter

Automated Response

When a sufficient number of pumps are still working for an LLC, no immediate action is taken.

When there are insufficient working LLC pumps to maintain an LLC, then the XSCF driver is used to send a shutdown request to all domains in this box.

Impact

The CPUs cooled by the failed LLC are deconfigured.

Indicted Hardware

The CMU, where this pump is mounted, is marked for replacement.

For M10-4/4S system with 4 CPU chip in a box, configuration of PCIe fabric will be changed triggered by CPU chip deconfiguration. This is taken place when ioreconfigure is set to true by setpparmode command.

Configuration of PCIe fabric is changed as follows:

- When CPU#0 on CMUL is deconfigured: Configuration of PCIe switch 0 is changed to allow access from CPU#0 on CMUU to built-in SAS chip, USB chip and GbE i/f #0 and #1. Configuration of PCIe switch 1 is changed to allow access from CPU#0 on CMUU to the first PCIe slot.

- When CPU#1 on CMUL is deconfigured: Configuration of PCIe switch 2 is changed to allow access from CPU#1 on CMUU to the fourth and fifth PCIe slots. Configuration of PCIe switch 3 is changed to allow access from CPU#1 on CMUU to the eighth and ninth PCIe slot.

- When CPU#0 on CMUU is deconfigured: Configuration of PCIe switch 0 is changed to allow access from CPU#0 on CMUL to built-in GbE i/f #2 and #3. Configuration of PCIe switch 1 is changed to allow access from CPU#0 on CMUL to the second and third PCIe slots.

- When CPU#1 on CMUU is deconfigured: Configuration of PCIe switch 2 is changed to allow access from CPU#1 on CMUL to the sixth and seventh PCIe slots. Configuration of PCIe switch 3 is changed to allow access from CPU#1 on CMUL to the tenth and eleventh PCIe slot.

Suggested Action for System Administrator

The recommended service action for this event is to schedule replacement of the affected component(s) at the earliest possible convenience. Although the hardware may be functioning, it is not intended nor recommended that the faulted component(s) remain in the system for a prolonged period of time.

Refer to the following document for the latest procedures for displaying event content in preparation for submitting a service request and applying any post-repair actions that may be required.
