Dell730xd Server and IntelX520 Gigabit NIC compatibility Problem resolution process

I. BACKGROUND

In a project POC site, implementation of the company based on the community OpenStack Mitaka Two development of private cloud products, the company packaged product image to fill the dell730xd server, the server network card configuration is 4 Gigabit 2个万 Gigabit (Intel X52 million gigabit network card).

In the product Cloud pipe configuration interface, found that the Intel 5.2 million Gigabit network card is not recognized

SSH-to-server discovery via IP link show to view Gigabit NICs that do not recognize the Intel X520

This POC, the Gigabit NIC module on the client server uses the Huawei SFP optical module

After filling the company's packaged product image, the system starts the following error

From the error message, the server network does not support the Huawei SFP Optical module, consider the possibility of network card driver problems caused

Ii. Solutions

1. Uninstall Ixgbe driver, perform rmmod Ixgbe
2. Load Ixgbe driver, modprobe Ixgbe allow_unsupported_sfp=1
3. View driver already loaded, Lsmod |grep Ixgbe

You may experience the following issues

1. If the machine restarts, it will cause the server's Gigabit network card can not be recognized, this time only to load the network card driver to write to the system boot/etc/rc.d/rc.local configuration file

2. Need to increase/etc/rc.d/rc.local file execution permissions

3. Even if the server restarts, the Gigabit network card driver will not be lost, the server will be able to identify the million Gigabit network card
