HP SVA V2.0 Software Installation Guide

There are several prerequisites to beginning this process:
• You have a fully installed and configured HP XC cluster.
• You physically added and cabled a number of visualization nodes and support hardware
to the HP XC cluster. See the HP XC hardware installation documentation available at
www.docs.hp.com, or contact HP Field Service.
• You powered down the cluster with the exception of the head node, on which you will install
the SVA Software Kit.
You must reimage the cluster nodes as part of this process.
There are three possible installation scenarios:
• The SVA nodes are new to the HP XC cluster, and exceed the maximum number of nodes
set during the cluster_prep step of the HP XC installation.
• The SVA nodes already exist in the HP XC cluster and do not exceed the maximum number
of nodes set during the cluster_prep steps.
• The SVA nodes are new to the HP XC cluster and do not exceed the maximum node number
set during the cluster_prep steps.
1.5.1 New SVA Nodes Exceeding Maximum Number
The installation process for installing the SVA Software Kit on new nodes in an existing HP XC
cluster is similar to installing the SVA Software Kit from scratch as documented in Section 1.4.
Follow those steps, noting the following differences:
1. Begin the installation using the instructions in Section 1.4.2.
2. In Section 1.4.4, there is an item that is specific to installing on an existing HP XC cluster.
This step only applies if you are installing the SVA Software Kit on an existing HP XC cluster.
Run the following command immediately before the HP XC cluster_prep steps:
# /opt/hptc/sbin/reset_db
3. In Section 1.4.6, there is an item that is specific to installing on an existing HP XC cluster.
This step only applies if you are installing the SVA Software Kit on an existing HP XC cluster.
Run the following command immediately before beginning the Run the start_sys Utility to
Start the System and Propagate the Golden Image section in the HP XC Installation Guide:
# setnetboot –-node n[1-8]
The n represents the default prefix for the cluster. For example, enter viz[1–8] assuming
you specified viz for your cluster prefix at an earlier stage of the installation and have eight
visualization nodes to image (not counting the head node).
1.5.2 SVA Nodes Already Exist in Cluster
This scenario is less complicated. The high level steps are the following:
1. Install the SVA Software Kit from the CD following the instructions starting with Section 1.4.2
and continuing through and including Section 1.4.9.
When you reach Section 1.4.4, modify its instructions as follows:
