setting up the Remote Copy links, see 3PAR Remote Copy User Guide available at: http:// www.hp.com/go/saw or contact your HP representative.

•Each node in the Metrocluster must have TCP/IP connectivity to both local and remote 3PAR storage systems. HP recommends you to provide redundant network paths between the cluster nodes and the 3PAR storage systems.

•For each node in the site, there must be at least two alternately routed fibre channel paths to the local 3PAR storage system.

NOTE: The maximum number of SSH connections to a 3PAR storage array is 16.

Configuring an application in a Metrocluster with 3PAR Remote Copy environment

After you set up the hardware and verify the infrastructure requirements as specified in the section “Infrastructure Requirements” (page 314), for both the sites, you can install and configure the software.

To configure an application in a Metrocluster with 3PAR Remote Copy environment:

1.Install the required software on all nodes in the Metrocluster.

2.Create the cluster.

3.Setup the replication using 3PAR Remote Copy.

4.Setup the user to perform Remote Copy operations by Metrocluster.

5.Define storage units.

6.Configure modular Metrocluster package.

Install the required software on all nodes in the Metrocluster

To configure an application in the Metrocluster with 3PAR Remote Copy environment, you must install all the required software products and related patches on all nodes in the Metrocluster.

For information about the software required and supported versions, see Serviceguard Disaster Recovery Products Compatibility and Feature Matrix (Metrocluster with 3PAR Remote Copy) available at http://www.hp.com/go/hpux-serviceguard-docs –> HP Serviceguard Metrocluster with 3PAR Remote Copy.

Creating the Cluster

To create the cluster or clusters, see the procedure described in the Managing Serviceguard manual available at http://www.hp.com/go/hpux-serviceguard-docs. For a Metrocluster, create a single Serviceguard cluster with components on multiple sites. For Continentalclusters, create two distinct Serviceguard clusters on different sites.

Setting up replication using 3PAR Remote Copy

It is assumed that you have already created one or more Serviceguard clusters for use in a disaster recovery configuration.

To set up replication in a Metrocluster with 3PAR Remote Copy environment:

1.Ensure that the 3PAR storage systems are correctly cabled to each host system that runs packages whose data reside on the storage systems. You must create corresponding host definitions on each storage system. For more information, see the 3PAR Management Console Online Help or the 3PAR CLI Administrator’s Manual available at: http://www.hp.com/go/ saw or contact your HP representative.

2.Create Remote Copy Volume Group

Before creating Remote Copy volume groups, you must create volumes on each storage system separately through the normal volume creation commands. The volumes must be of the same
