IMPORTANT:

Under specific distributions, such as Red Hat Enterprise Linux 5 (RHEL 5), the

installation CD is auto-mounted using the following CD label:

# /media/HpInstallx.x/

If this occurs, the CD may get mounted with the no execution flag, causing the installation script

to fail. Installation failure may be indicated by the following error message:

# ./install_smb.sh

The following is returned:

bash: ./install_smb.sh: /bin/sh: bad interpreter: Permission denied

The workaround is to manually mount the installation CD. For example, if the CD was auto-mounted

in /media/HpInstallx.x, issue these commands to unmount, and then remount the CD:

# unmount /media/HpInstallx.x

# mkdir -p /mnt/cdrom

# mount /dev/cdrom /mnt/cdrom

If the unmount command fails with a busy warning, make sure that all applications and consoles

that could be using the CD media are closed, and then try again.

Change directory to the linux directory. For example, if the installation CD is mounted in
/mnt/cdrom

, issue the command:

# cd /mnt/cdrom/linux/

Run the install_smb.sh script as follows:

# ./install_smb.sh

This will install the following components:
• QLogic FC HBA driver
• HP Array Configuration Utility
• QLogic SANsurfer agent, QLRemote (if possible, the installation program will also start the

SANsurfer agent, QLRemote)

If the following message appears at the end of the installation, you must restart the computer, otherwise,

continue with

step 5

New driver and qlremote installed but not active.

For new driver and qlremote to be active either:

Reboot the system (Mandatory in case of Boot From SAN)

Stop all the applications using QLogic driver.

Unload QLogic driver by executing following command:

# modprobe -r qla2XXX (ex. qla2300, qla2400)

Reload new driver by executing following command:

# modprobe -v qla2xxx

Start qlremote as follows:

# /etc/init.d/qlremote start

Rebooting the system will automatically load new driver and start qlremote.

To verify that the installation completed, check the FC HBA driver version:
a. To ensure that the driver is installed in the correct location, issue the command shown in the

following example:

# modinfo qla2xxx

The following is returned:

Filename: /lib/modules/2.6.9-55.ELsmp/kernel/drivers/scsi/qla2xxx/qla2xxx.ko
