Installation guide

Installation instructions for the out of kernel QLogic driver

Installing and Configuring the Linux Host with the QLogic Driver

Note: EMC does not support the persistent binding implementation

contained within the QLogic driver. As a result, it is recommended that

the driver be compiled and installed without persistent binding enabled.

This can be accomplished by using the 'dp' switch with the installation

script.

Proceed with the installation.

cd qlafc-linux-8.xx.xx-1-install/./qlinstall -i -dp

The qlinstall installation script provides the following features:

◆ Installs the driver source RPM which installs the driver source

code in the following path:

/usr/src/qlogic/<driver_version-rpm_release>

◆ Builds and installs the QLogic driver and configuration module

(

qla2xxx_conf.o) for the QLogic adapter model(s) installed in

the system.

◆ Creates back-ups of important files and older drivers in the

following directory:

/usr/src/qlogic/<driver version-rpm release>/backup

◆ Automatically loads the driver for the adapter model present.

◆ Builds and installs the ramdisk with the latest driver and

configuration modules.

◆ Installs the QLogic SNIA API Library V2.

◆ Performs device discovery by default.

◆ Provides the following command line options:

• To invoke the device discovery at a later stage.

• To rebuild the ramdisk excluding or including QLogic adapter

driver.

• To unload/load driver.

• To update the option ROM (BIOS, and so forth) on all

adapters.

• To update the NVRAM on all adapters.

• To pass driver parameters. For example:

ql_port_down_retry

(Overrides NVRAM default)
