HP Serviceguard for Linux Version A.11.18 Deployment Guide, August 2008

e. Click “OK” to the warning.

Preparing the Servers

In preparation for the Serviceguard for Linux installation and configuration steps, the two servers need

to be configured to meet the minimum requirements for Serviceguard in terms of redundant paths to

the external storage server, shared storage configuration and network redundancy.

NOTE: If you haven’t already done so, copy all downloaded software files to a directory on each

server, /tmp/sglx_install, for example.

Install and Configure Driver for Fibre Channel HBA

New drivers will probably be required for the Fibre Channel HBA card used to connect each server to

the shared storage device. These instructions are for the QLogic HBA cards recommended in the

“What to Order” section. Be sure to get the driver appropriate for your systems’ HBA cards.

These steps need to be executed on each server.

The following examples are for the QLogic driver, version 8.01.07.25-1. If a newer driver is

available, change the command arguments accordingly.

1. Check to see if a QLogic driver is already installed:

rpm –qa | fgrep hp_qla2x00src

If the QLogic driver is not installed, there will be no output from this command. If the QLogic

driver is already installed, you will see command output showing the version, for example:

hp_qla2x00src-8.01.07.25-1

2. If it is an earlier version than the one downloaded, remove it:

rpm –e hp_qla2x00src

3. Change to the directory where the kit has been downloaded, for example:

cd /tmp/sglx_install

4. Untar the driver kit using the following command:

tar xfzv hp_qla2x00-2007-10-05.tar.gz

5. Change directory to the hp_qla2x00-yyyy-mm-dd directory. For example,

cd hp_qla2x00-2007-10-05

6. Install the driver and fibreutils packages, for example:

rpm -ivh hp_qla2x00src-8.01.07.25-1.linux.rpm

rpm -ivh fibreutils-2.4-1.linux.i386.rpm

Configuring Multipath Support

Support for multiple Fibre Channel paths from each server to the MSA2000 is provided using HP

Device Mapper Multipath.

The steps in this section need to be executed on each server.

1. Go to the directory where the HP Device Mapper Multipath Enablement Kit has been

downloaded, for example:

cd /tmp/sglx_install

2. Untar the driver kit using the following command:

tar xfzv HPDMmultipath-4.0.0.tar.gz

3. Change to the HPDMmultipath-X.Y.Z directory, for example:

cd HPDMmultipath-4.0.0

NOTE: The documentation for HPDMmultipath is included in the kit and can be found under

the docs directory, if needed.
