7 Dynamic Addition and Removal of Hosts

As workloads ramp up and the demand for CPU cycles increases, additional hosts may be

added to bear the burden of additional VMs that can provide added compute power. The

scripts instRHELH.sh and instRHEVH.sh may be used to create a new host of each type.

7.1 RHEL / KVM Host Addition

The instRHELH.sh script requires a single passed parameter, the server blade profile name

assigned in the Virtual Connect interface.

./instRHELH.sh rhelh-02

The script:

• creates the cobbler system entry

• presents storage to the host

• adds the new NFS export stanza to the cluster configuration file

• sets the boot order to boot PXE first

• registers the host with satellite after install

• sets the boot order to boot PXE last

and requires the user to add the newly created RHEL host in RHEV-M.

instRHELH.sh

#!/bin/bash

# This script will install and prepare a system to be a RHEL host

# Source env vars

if [[ -x varDefs.sh ]] ; then

source varDefs.sh

elif [[ -x /root/varDefs.sh ]] ; then

source /root/varDefs.sh

elif [[ -x /root/resources/varDefs.sh ]] ; then

source /root/resources/varDefs.sh

elif [[ -x /root/distro/resources/varDefs.sh ]] ; then

source /root/distro/resources/varDefs.sh

else

echo "didn't find a varDefs.sh file"

# The blade profile must be passed

if [[ $# -ne 1 ]]

then

echo 'Usage - $0 <HP Virtual Connect profile name>'

exit -1

else

pname=$1
