Installing and updating a QLogic driver on an Intel or AMD host running Linux

This section describes how to install and update a QLogic fibre-channel adapter driver on an Intel host running the Linux operating system.

Perform the following steps to install a QLogic adapter driver:

Install the adapter driver. See the specific adapter driver installation instructions that are provided by your host adapter vendor.
Note: The Interoperability Matrix at http://www.ibm.com/servers/storage/disk/ds6000/ provides the supported driver levels for your QLogic adapter. If the supported level differs from the preinstalled version of the driver, go to Downloading and installing a host adapter driver or http://support.qlogic.com/support/oem_ibm.asp. Most Linux distributions now provide QLogic adapter driver support as part of the kernel package.
Verify that the QLogic adapter driver module is loaded using the host system command lsmod. Look for the module name beginning with qla.
Determine the kernel version that you are running. Obtain the kernel version by running the host system command uname -r. The version can be either 2.4x or 2.6x.
Type cat /proc/scsi/qlaxxx/n, where xxx is the extension for the driver, and n is the host adapter port that is represented in Linux as a SCSI host bus. For example, the driver extension might be 2300, or 2xxx, and the host adapter port might be Firmware version 3.03.02 IPX, Driver version 8.00.00b21-k. The firmware is included with the driver version
Perform one of the following steps to bring the new driver online:
- Restart the server. This is the most efficient option.
- Remove and add the module using the modprobe Linux command.
