Síntomas
After a BIOS update, some PCIe addresses report different values.
Before BIOS update:
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]
After BIOS update:
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]
Causa
This change was implemented intentionally to standardize PCIe address assignments on PowerEdge XE systems. The following systems include this update:
BIOS Version 2.4.4 and later:
- XE9680
- XE9680L
BIOS Version 2.5.4 and later:
- XE8640
- XE9640
Resolución
The change in PCIe device addressing is expected behavior following the BIOS update.
