If any of these devices are not displayed as shown above, you should shut down your system (computer first, then the expansion chassis) and
reconnect the cables and the PCIe expansion host card to ensure that you have a solid connection. Then restart the OSS expansion chassis
followed by the computer. Next, try to verify the installation again, as shown above. If you are still having problems, contact OSS Technical
Support at (858) 530-2511.
3.4 RedHat Linux
Once the EB7-X8G2-RAS has been installed in a RedHat9-based system, its installation can be verified by typing the following command lines:
lspci
–
t
Displays the overall structure of the PCIe expansion system
lspci
–
vv
Lists additional information about the PCIe switch (in our case it will list the Integrated Device Technology (IDT) information.
Ispci
–
vvv
Displays the most comprehensive information about the expansion system.
Typical output from lspci –vvv is verbose, but you can dig through the information to find very important information. There are so many
registers and settings associated with PCI Express Switches.
For example, below is showing the OSS Chassis on Bus 7, Device 0, Function 0. Some information has been deleted, but notice the Link
Supported Speed is 5.0 Gb/s, Width x8 . This is helpful to know that the chassis is configured for x8 PCI Express Speeds highlighted in red.
