Installing PowerPath

in a New AAM

Cluster

This section describes how to:

◆Install PowerPath and Legato Automated Availability Manager (AAM) in a new cluster, that is, where neither the PowerPath nor the AAM software is installed on any host to be included in the cluster.

◆Integrate PowerPath into an existing AAM cluster.

To install and configure PowerPath and AAM 5.1 (or later) when neither PowerPath nor AAM is installed:

1.Prepare the cluster environment. Refer to the EMC Host Connectivity Guides or the Installation Roadmap for FC-Series Storage Systems and the relevant AAM documentation.

2.Use the Solaris format utility to verify that all storage system devices are seen by each host.

3.Install PowerPath on all nodes. Refer to Chapter 1, Installing PowerPath.

4.Install AAM 5.1 (or later) on all nodes. Refer to the relevant AAM documentation.

5.Add PowerPath Volume Manager resources to AAM resource groups. Refer to the relevant AAM documentation.

6.If the AAM agent is not already started, start the agent on each node in the cluster, using either the ft_startup command or the Management Console.

7.Verify that the resource group is up and running, and use either the ftcli command ListResourceGroups or the Management Console to verify that the resource group can fail over to all nodes in the cluster.

8.Set a common minor number for every PowerPath Volume Manager volume in the cluster. Refer to Setting Major and Minor Numbers on page 2-13 for information on setting the minor number.
