3.7.15 Mount Network File Systems

This task is optional. If you plan to mount NFS file systems, add the mount points to the

/hptc_cluster/etc/fstab.proto file now so that the mount points are propagated to the

golden image.

NOTE: See the HP XC System Software Administration Guide if you need more information about

how to modify the /hptc_cluster/etc/fstab.proto file.

3.7.16 Update initrd Files With Required Hardware

This task is optional. When client nodes contain additional hardware that is required for booting

(such as SCSI controllers) and the hardware is not present on the head node, you must modify

the initrd file on the head node to include the drivers.

NOTE: Perform this task now before running the cluster_config utility. Performing this

task after running the cluster_config utility requires you to remove the golden image.

Example 3-4 provides a sample script that updates all initrd files if a client node contains the

Adaptec SCSI controller:

Example 3-4 Script To Update initrd Files With Hardware Required For Booting

#!/bin/bash

FILES=`find /boot -name initrd\* -print`

for i in $FILES

VERSION=`echo $i | sed -e 's/^.*initrd-$.*$.img/\1/'`

if [ ! -z "$VERSION" ]

then

NEWF=/tmp/initrd-$VERSION.img

echo "/sbin/mkinitrd --with=aacraid -f $NEWF $VERSION"

/sbin/mkinitrd --with=aacraid -f $NEWF $VERSION

if [ -f $NEWF ]

then

echo "replacing $i with $NEWF"

rm $i

mv $NEWF $i

done

3.8 Task 7: Run the cluster_config Utility to Configure the System

The next step in the process is to configure the system. In this task, use the cluster_config

utility to review default role assignments and modify the role assignments on all nodes in the

system based on the size of the system (and other considerations, such as improved availability).
