Broadcom 10 Gb Ethernet Expansion Card (CFFh) p/n: 44W4465 and p/n: 44W4466 is unsupported with RHEL 6 and later - IBM Servers



Source

RETAIN tip: H21763

Symptom

After updating operating system (OS) to Red Hat Enterprise Linux (RHEL) 6.x the device driver (bnx2x) for Broadcom 10 Gigabit (Gb) Ethernet Expansion Card (CFFh) will start dropping network packets and will cause network congestion resulting in loss of communication from the network interface(s) associated with the (bnx2x) device.

The output from '/var/log/messages' will show access timeout events similar to the messages below:

  Nov 15 10:11:43 RHEL6-2-6 kernel: bnx2x 0000:15:00.1: eth16: MDC/MDIO access timeout
Nov 15 10:11:43 RHEL6-2-6 kernel: bnx2x 0000:15:00.1: eth16: MDC/MDIO access timeout
Nov 15 10:11:44 RHEL6-2-6 kernel: bnx2x 0000:15:00.0: eth15: MDC/MDIO access timeout

Affected configurations

The system may be any of the following IBM servers:

  • BladeCenter HS12, type 1916, any model
  • BladeCenter HS12, type 8014, any model
  • BladeCenter HS12, type 8028, any model
  • BladeCenter HS22, type 1911, any model
  • BladeCenter HS22, type 1936, any model
  • BladeCenter HS22, type 7870, any model
  • BladeCenter HS22V, type 1949, any model
  • BladeCenter HS22V, type 7871, any model
  • BladeCenter HS23, type 1929, any model
  • BladeCenter HS23, type 7875, any model
  • BladeCenter HS23E, type 8038, any model
  • BladeCenter HS23E, type 8039, any model
  • BladeCenter HX5, type 1909, any model
  • BladeCenter HX5, type 1910, any model
  • BladeCenter HX5, type 7872, any model
  • BladeCenter HX5, type 7873, any model

The system is configured with at least one of the following:

  • Red Hat Enterprise Linux 6, any update

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

  • Broadcom 10 Gb Dual-Port Ethernet Expansion Card (CFFh) for IBM BladeCenter, Option part number 44W4466, any replacement part number
  • Broadcom 10 Gb Quad-Port Ethernet Expansion Card (CFFh) for IBM BladeCenter, Option part number 44W4465, any replacement part number

The bnx2x device driver for the Broadcom 10 Gb Expansion Card (CFFh) is affected.

Note: This does not imply that the network operating system will work under all combinations of hardware and software.

Please see the compatibility page for more information:

http://www.ibm.com/systems/info/x86servers/serverproven/compat/us/

The system has the symptom described above.

Solution

In order to fix the issue, Broadcom 10 Gb Dual-Port and Quad-Port Ethernet Expansion Cards (CFFh) (p/n: 44W4465 and p/n: 44W4466) should be upgraded to the new Broadcom 10 Gb Gen 2 Dual-Port and Quad-Port Ethernet Expansion Cards (CFFh) (p/n: 46M6168 and p/n: 46M6164) respectively.

Note: The upgrade of Broadcom 10 Gb Dual-Port and Quad-Port Ethernet Expansion Cards is not covered under IBM warranty. For information on the IBM Statement of Limited Warranty, contact IBM representatives or resellers.

Additional information

The Broadcom 10 Gb Dual-Port and Quad-Port Ethernet Expansion Cards are legacy devices and do not work with new versions of Red Hat Enterprise Linux 6 and later.
