6 Configuring SAN Storage Devices

This chapter addresses the following topics:

• Making and Mounting the SAN Storage File Systems (page 74)

SAN Storage Overview

An MSA1000 storage array is an option in an HP Cluster Platform cluster. The MSA1000 is shipped with a

cable that enables you to establish an administrative connection to the array’s storage controllers. You use

this connection to open a command terminal and issue Array Configuration Utility (ACU) commands to the

controllers. The HP XC implementation of the ACU provides a command-line interface (CLI) only. The controller

management cable is a serial console cable. This cable has a DB-style female plug, which you connect to

the port labeled console serial A on the head node. The other end of the cable is a male RJ-45Z plug, which

you connect to the RJ-45Z port on the front of the controller.

The host bus adapter (HBA) driver for the SAN connection to an EVA system is delivered with the HP XC

System Software and is installed by default on CP6000 systems when the HBA interface hardware card is

present on a node.

On CP3000 and CP4000 cluster platforms, the HBA driver is not loaded automatically. On those systems,

you must load the driver manually using the modprobe qla2300 command. The qla2300 drivers are

included in the HP XC System Software.

Follow this procedure to make the load automatic:

1. Begin this procedure as the root user on the head node.

2. Use the text editor of your choice to edit the following file:

/etc/rc.d/rc.sysinit

3. Add the following text above the update_boot_stage RCraid definition near the end of the file:

/sbin/lspci | /bin/grep QLA

if [ $? = 0 ]; then

/sbin/modprobe qla2300

After editing, the file should look similar to this:

# Load modules (for backward compatibility with VARs)

if [ -f /etc/rc.modules ]; then

/etc/rc.modules

# Load qla 2300 driver if an HBA is installed

/sbin/lspci | /bin/grep QLA

if [ $? = 0 ]; then

/sbin/modprobe qla2300

update_boot_stage RCraid

4. Save your change and exit the file.

5. If the HBA is installed on the head node, you are done. If the HBA is installed on a node other than the

head node, continue with the remaining steps in this procedure.
