PowerPath in a Legato 5.1 (or later) AAM Cluster
This section describes how to:

Installing PowerPath
in a New 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.
