PowerPath in a Sun Cluster 2.2

Installing PowerPath in a New Sun Cluster 2.2

This section describes how to:

◆Install PowerPath and Sun Cluster 2.2 in a new cluster, that is, where neither the PowerPath nor the Sun Cluster 2.2 software is installed on any host to be included in the cluster.

◆Integrate PowerPath into an existing Sun Cluster 2.2 cluster.

To install and configure PowerPath and Sun Cluster 2.2 when neither PowerPath nor Sun Cluster 2.2 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 Sun Cluster documentation.

Make sure VxVM DMP is disabled. (Refer to Installing and Configuring emcpower Devices with Solaris Applications, available on the Powerlink website.)

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 Sun Cluster 2.2 on all nodes. Refer to the relevant Sun Cluster documentation.

5.If necessary, configure the quorum device on all nodes.

You cannot use a VCMDB device as the quorum device.

6.Initialize the root disk group on all nodes.

7.Initialize PowerPath devices on all nodes.

8.Start cluster services on the master node.

9.Designate/create shared disk groups on the master node.

10.Create logical volumes from the designated shared disks.

11.Create a logical host.

12.Start cluster services on the other (non-master) nodes.
