Abstract

This document describes the steps needed to install and integrate HP Data Protector Cluster Cell Manager on the Red Hat Cluster Suite (RHCS).

Introduction

This document describes the installation and integration of Cluster-aware Cell Manager on a Linux Cluster. The Red Hat Cluster Suite (RHCS) is considered as an example.

Cluster-aware application: An application that calls cluster APIs to determine the context under which it is running, such as the virtual server name, and that can fail over between nodes for high availability.

Cluster-aware Cell Manager: A cluster-aware application that supports the cluster Application Programming Interface (API). Each cluster-aware application declares its own critical resources. In the case of a Data Protector Cell Manager (CM), the critical resources are volume groups, application services, and virtual server.

In order to configure the Cluster-aware Cell Manager, the following resources are mandatory:

•Shared Disk group, configured with either a gfs or gfs2 File System

•Virtual server, which can be pinged using host name, which will act as the Cell Manager

•Data Protector cluster services

This white paper describes the following:

•How to integrate the cluster-aware Cell Manager in cluster environment

•How to setup a data protector cluster service in failover mode on the Red Hat Cluster Suite

Integrating a cluster-aware Cell Manager on RHCS

Prerequisites

•Two servers with RHEL OS installed and RHCS (HA) configured on them

•Two NIC cards on each machine: one configured with private IP, to check the heart beat of nodes, and the other with a public IP address, for external communication

For example: Public/Private IP:

Node1: 10.10.1.82/192.168.0.10

Node2: 10.10.1.81/192.168.0.11

•Two disks of 4 GB capacity, shared between the two System/Nodes either using FC SAN or iSCSI

SAN

•OS repository

•Virtual Server configured on the cluster. For example: server: dpi00180 with IP address: 10.10.1.9

•Basic understanding of RHCS, HA, and Data Protector Cell Manager

•Deciding which systems are going to be the Primary Cell Manager and the Secondary Cell Manager. Both of them must be configured as cluster members.

•For example: Primary Node: dpi00182, Secondary Node: dpi00181

•Valid HP Data Protector Cluster Cell Manager license
