Symptoms

Efter en BIOS-opdatering rapporterer nogle PCIe-adresser forskellige værdier.

Før BIOS-opdatering:

01:00.0 Ethernet controller: Broadcom Inc. and subsidiaries NetXtreme BCM5720 Gigabit Ethernet PCIe

01:00.1 Ethernet controller: Broadcom Inc. and subsidiaries NetXtreme BCM5720 Gigabit Ethernet PCIe

2a:00.0 Ethernet controller: Mellanox Technologies MT2892 Family [ConnectX-6 Dx]

2a:00.1 Ethernet controller: Mellanox Technologies MT2892 Family [ConnectX-6 Dx]

54:00.0 Ethernet controller: Mellanox Technologies MT2910 Family [ConnectX-7]

67:00.0 Ethernet controller: Mellanox Technologies MT2910 Family [ConnectX-7]

d1:00.0 Ethernet controller: Mellanox Technologies MT2910 Family [ConnectX-7]

e3:00.0 Ethernet controller: Mellanox Technologies MT2910 Family [ConnectX-7]
 

Efter BIOS-opdatering:

01:00.0 Ethernet controller: Broadcom Inc. and subsidiaries NetXtreme BCM5720 Gigabit Ethernet PCIe

01:00.1 Ethernet controller: Broadcom Inc. and subsidiaries NetXtreme BCM5720 Gigabit Ethernet PCIe

27:00.0 Ethernet controller: Mellanox Technologies MT2892 Family [ConnectX-6 Dx]

27:00.1 Ethernet controller: Mellanox Technologies MT2892 Family [ConnectX-6 Dx]

4d:00.0 Ethernet controller: Mellanox Technologies MT2910 Family [ConnectX-7]

5e:00.0 Ethernet controller: Mellanox Technologies MT2910 Family [ConnectX-7]

ca:00.0 Ethernet controller: Mellanox Technologies MT2910 Family [ConnectX-7]

da:00.0 Ethernet controller: Mellanox Technologies MT2910 Family [ConnectX-7]

Cause

Denne ændring blev implementeret bevidst for at standardisere PCIe-adressetildelinger på PowerEdge XE-systemer. Følgende systemer indeholder denne opdatering:

BIOS-version 2.4.4 og nyere:

  • XE9680
  • XE9680L

BIOS-version 2.5.4 og nyere:

  • XE8640
  • XE9640

Resolution

Ændringen i PCIe-enhedsadressering er forventelig adfærd efter BIOS-opdateringen.

Affected Products

PowerEdge XE8640, PowerEdge XE9640, PowerEdge XE9680
