Installing PowerPath

in a New VCS

Cluster

This section describes how to:

◆Install PowerPath and VCS in a new cluster, that is, where neither the PowerPath nor the VCS software is installed on any host to be included in the cluster.

◆Integrate PowerPath into an existing VCS cluster.

For new installations of VxVM, use native c#t#d# devices. Do not initialize emcpower devices for VxVM using powervxvm.

If emcpower devices already exist in a VxVM disk group that is being added as a resource group to VCS, those devices should remain in the disk group as emcpower devices for as long as they comprise active VxVM logical volumes.

To install PowerPath and VCS when neither PowerPath nor VCS is installed on any host:

1.On each host to be included in the cluster:

a.Prepare the cluster hardware, making the necessary networking and disk connections among the hosts and the storage system. Refer to the EMC Host Connectivity Guides or the Installation Roadmap for FC-Series Storage Systems and the relevant VERITAS Cluster Server documentation for more information.

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

c.Install PowerPath and, if you are using PowerPath Volume Manager in the cluster, the PowerPath Volume Manager VCS Agent. Refer to Chapter 1, Installing PowerPath. Verify that PowerPath can see all the devices.

d.Install any applications.

e.Install the VCS software, following the installation procedure described in the relevant VERITAS Cluster Server documentation. Initially configure VCS to run without a service group.

If you are using PowerPath Volume Manager in the cluster, proceed with step 2. If you are not using PowerPath Volume Manager, go to step 3.
