11–Troubleshooting Guidelines Caveats

PCI Express Slot

The QLogic adapter can be located on the PCI Express bus using the following Linux procedures.

Determine the vendor and device ID. To check if the PCIe slot has a x8 link for optimal PCIe performance, first determine the PCI vendor ID and device ID code by typing the following command:

% lspci -n

You should see a message similar to:

06:00.0 0200: 4040:0100 (rev 42)

The QLogic vendor ID is 0x4040. A list of QLogic adapter device IDs is listed in Table 11-3.

Description

 

 

 

QLE3044

0124

Quad-port 1GbE copper interface

 

 

 

QLE3142-CU

0126

Dual-port 10GbE with twinax interface

 

 

 

QLE3142-SR

0126

Dual-port 10GbE with short-range fiber interface

 

 

 

QLE3142-LR

0126

Dual-port 10GbE with long-range fiber interface

 

 

 

Determine the interface attributes. To determine the attributes of the interface, type the following command:

% lspci -n -d 4040:0100 -vvv grep -i width

You should see a message similar to:

Link: Supported Speed 2.5 Gb/s, Width x8, ASPM L0s, Port 0

Link: Speed 2.5Gb/s, Width x8

Determine the width parameters. Check if the lspci output “negotiated width” (the second width in the output) reflects the actual “supported width”. In an system with a QLE3044, for example, type the following command to determine if these two widths are the same:

% lspci -xxx -vvv -d 4040:0100

In the previous command, 4040 indicates the QLogic vendor ID and 0124 indicates a QLE3044. The device ID is 0126.
