Symptoms

Dopo un aggiornamento del BIOS, alcuni indirizzi PCIe riportano valori diversi.

Prima dell'aggiornamento del BIOS:

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]
 

Dopo l'aggiornamento del BIOS:

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

Questa modifica è stata implementata intenzionalmente per standardizzare le assegnazioni degli indirizzi PCIe sui sistemi PowerEdge XE. I seguenti sistemi includono questo aggiornamento:

BIOS versione 2.4.4 e successive:

  • XE9680
  • XE9680L

BIOS versione 2.5.4 e successive:

  • XE8640
  • XE9640

Resolution

La modifica dell'indirizzamento dei dispositivi PCIe è un comportamento previsto dopo l'aggiornamento del BIOS.
