4
Purpose and intended audience
The purpose of this white paper is to:
• Introduce the reader to the Easy Deployment feature in HP Serviceguard and Serviceguard Manager
• Describe Easy Deployment in the context of cluster configuration—cluster Easy Deployment
• Describe Easy Deployment in the context of package configuration—package Easy Deployment
• Help customers understand prerequisites and usage details for Easy Deployment of a cluster/package using
Serviceguard Manager, in order to effortlessly meet their high availability needs
This document is intended for users who are familiar with Serviceguard configuration and installation. Users must be
aware of installation of toolkits, and the installation/configuration procedures of the supported applications.
Definition of terms
Terms Definition
CFS Cluster File System allows multi-system shared access to common file system.
Complex workload
package
A multi-instance application that uses active resources across multiple nodes in a cluster.
These workloads are configured using multiple inter-dependent multi-node or failover packages in a cluster.
The workloads need to be managed and moved collectively for disaster tolerance.
MNP Multi-node package, a Serviceguard package that runs on multiple nodes at the same time and can be
independently started and halted on individual nodes.
OC Oracle Clusterware can run in conjunction with Serviceguard Extension for RAC and can provide Oracle
cluster membership and resource management services.
OCR Oracle Cluster Registry
RAC Real Application Cluster enables a multi-instance concurrent shared access database.
SADTA SADTA enables deploying complex workloads in a Metrocluster. Complex workloads are applications
configured using multi-node and failover packages with dependencies. These packages, referred to as
complex workload packages, are configured over isolated sub-clusters, such as Oracle Clusterware, or
Serviceguard Storage Management Suite (SG SMS) Cluster File System, which are created within the
Metrocluster. Sub-clusters have access only to the storage arrays within their respective sites.
SG SMS Serviceguard Storage Management Suite Software
SGeRAC Serviceguard Extension for RAC extends Serviceguard to support Oracle RAC.
SGeSAP Serviceguard Extension for SAP extends Serviceguard to support SAP NetWeaver environments.
Site controller
package
A Metrocluster failover package to provide coordinated automatic site failover for the configured complex
workload. It is created using a Metrocluster modular package module: dts/sc.
Voting disk Shared storage used by Oracle Clusterware as vote tie breaker and for disk-based heartbeat
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.
