HP Scalable Visualization Array, V1.1 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 step.
• The SVA nodes are new to the XC cluster and do not exceed the maximum node number set during the
cluster_prep step.
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 “Full Software Installation from
Scratch” (pg. 11). Follow those steps, noting the following differences:
1. Begin the installation using the instructions in “Optional Remote Graphics Software Notes” (pg. 11).
2. In “Configuring and Imaging the HP XC System” (pg. 13), 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 step:
# /opt/hptc/sbin/reset_db
3. In “Golden Image the Render/Display Nodes” (pg. 14), 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
Start the System and Propagate the Golden
Image
section:
# 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).
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.
2. Install HP XC starting from the cluster_config steps.
For details, see “Full Software Installation from Scratch” (pg. 11).
New SVA Nodes Not Exceeding Maximum Number
This scenario is less complicated. The high level steps are the following:
1. Install the SVA Software Kit using the CD.
2. Install HP XC starting with the discovery process.
For details, see “Full Software Installation from Scratch” (pg. 11).
