Symptoms

  • Redfish API call to: 
    /redfish/v1/Chassis/System.Embedded.1/NetworkAdapters
    Returns an additional invalid member such as: 
    NIC.Embedde2
  • When queried individually, the invalid URI results in an error.
  • PowerEdge iDRAC UI filters out the invalid entry, but API consumers see the incorrect resource.
  • BIOS and iDRAC versions observed during issue:
    • BIOS: 1.0.1
    • iDRAC Firmware: 7.20.70.50

Cause

  • Incorrect Vital Product Data (VPD) in the initial build of the optional LOM card caused improper device capability mapping.
  • The mapping described only a single port while the card has two ports, leading to cosmetic and API-level inconsistencies.
  • Also, a design change increased the LOM firmware Root of Trust signing key size to 4K bytes, requiring updated firmware for proper signature validation.

Resolution

  • Workaround:

    • Apply the latest Broadcom LOM firmware update (version 22.xx.x.x or later).
    • Perform the Dell Update Package (DUP) from within a supported operating system and reboot the server.
    • Do not apply the update by iDRAC or Lifecycle Controller; it must be done from the operating system.

  • Permanent Fix:

    • Use iDRAC firmware version 5.10.25.00 (T6RVR X45) or later with:
      • LOM firmware DFF48 X05 or later, or
      • LOM firmware JFF2M X02 or later
    • These versions include corrected VPD and updated signing key logic.

Additional Information

  • Affected Platforms: Dell PowerEdge servers with Broadcom NetXtreme Gb LOMs
  • Affected Components: Optional LOM cards and embedded NICs.
  • Severity: Standard
  • Fixed Firmware Builds:
    • LOM firmware: DFF48 X05 or later
    • iDRAC firmware: T6RVR X45 or later
