Server Bus/Device/Function Number (B/D/F) Information
The server's B/D/F information may change with PCIe card configurations. You can
obtain the B/D/F information of the server using the following methods:
● BIOS serial port log: If the serial port log has been collected, you can query the
B/D/F information of the server by searching for the keyword "dumpiio".
● UEFI Shell: You can obtain the B/D/F of the server using the pci command. Run
the help pci command to obtain the specific usage of the pci command.
● You can obtain the B/D/F of the server using the pci command. Run the help pci
command to obtain the specific usage of the pci command.
– Linux OS: You can obtain the B/D/F information of the server using the lspci
-vvv command.
If the OS does not support the lspci command by default, obtain the pci-utils
package from the yum source and install it to make the OS support the command.
– Windows OS: After installing the pci-utils package, run the lspci command
to obtain the B/D/F information of the server.
– VMware OS: The lspci command is supported by default. You can directly
obtain the B/D/F information of the server using the lspci command.
