Configure the QLogic Adapter on Linux

8–Linux Driver Installation and Configuration Configure the QLogic Adapter on Linux

To configure the QLogic adapter:

1.Type one of the following commands to identify the Ethernet interface (eth1, eth2, etc.) and the nx_nic driver from the command line:

%cat /proc/net/nx_nic/dev0/stats grep eth or

%ifconfig -a

Look for the interface with a MAC address (HWaddr) prefix of 00:0E:1E:XX:XX:XX

2.Type the following to commands assign an IP Address and activate the interface:

%ifconfig eth[n] down

%ifconfig eth[n] <IP Address> netmask <Netmask Value> up

3.Verify that the network services are running, and then type:

%service network restart

To verify connectivity, contact a different IP address using the ping command.

Uninstall the Commercial GPL Driver and Tools Package

Type the following commands to uninstall the commercial GPL driver and tools, which are part of the RPM package:

%rpm -qa grep nx_

%ifconfig eth[n] down

%rmmod nx_nic.ko

%rpm -e nx_nic-[version]1

%rpm -e nx_tools-[version]

Diagnostic Tests for the QLogic Adapter

The Linux user diagnostics utility performs various tests using the

./nxudiag -i eth[n] command.

The syntax for these tests is:

%./nxudiag [command-options-and-arguments]

See Table A-1for a list of Linux diagnostic utility commands.

1[version] refers to the RPM package currently on the system. RPM packages can be located by executing the command: rpm -qa grep nx_.
