Using Easy Deployment in Serviceguard and Metrocluster environments on HP-UX 11i v3

Cluster Easy Deployment

Introduction

Cluster Easy Deployment is targeted to simplify and speed up the process of bringing up a new

cluster, with a lower level of required expertise.

This cluster Easy Deployment feature is supported by both Serviceguard Manager and the

Serviceguard command-line interface.

In Serviceguard Manager, this feature simplifies cluster configuration with various environments, by

providing an interactive wizard, bolstered with ample auto-discovery.

Cluster Easy Deployment is also supported on the command line with the cmdeploycl command. This

command eases cluster-related storage and network configuration aspects.

Software prerequisite

• Serviceguard A.11.20 plus PHSS_41628 or superseding patch must be installed on all nodes.

Cluster Easy Deployment using Serviceguard Manager

The cluster Easy Deployment feature helps the users by performing the following tasks:

• Set up cmclnodelist after selection of nodes

• Configure shared subnets (network configuration)

• Configure cluster-wide device special files

• Perform cluster lock selection and create shared storage, if needed

• Update system files on cluster nodes

Enable CFS or CVM in the cluster

The following prerequisites need to be satisfied to use the cluster Easy Deployment feature to enable

CFS or CVM in the cluster:

• The SG SMS versions A.03.01 or later with Serviceguard A.11.20 plus PHSS_41628 or

superseding patch need to be pre-installed.

• The user must ensure that vxinstall has been run on all nodes of the cluster.

When a SG SMS CFS or CVM standalone bundle is installed on all the nodes, the users will be

prompted to choose if they would like to enable CFS or CVM in the cluster. As part of this, the SG-

CFS-pkg (SMNP) will be automatically configured during cluster deployment. This package is the

system multi-node package (SMNP) that runs the CVM infrastructure. It configures and starts the

CVM/CFS stack.

SGeRAC cluster Easy Deployment

The following products need to be pre-installed to use the SGeRAC cluster Easy Deployment feature:

• SGeRAC A.11.20 Patch—PHSS_41642 or superseding patch

• Oracle RAC 11g R2

When the SGeRAC product is installed on all the nodes, the cluster Easy Deployment feature checks if

the following conditions are satisfied:

• The cluster configuration has the same LAN interface name on all nodes.

• The cluster is not configured with IPv6 heartbeat.
