• Add or remove storage systems to the cluster if necessary to ensure you can have equal numbers of storage systems in each site. The wizard will not let you create sites with different numbers of storage systems; nor will it let you leave unassigned any storage systems currently in the cluster. Using the Multi-Site cluster wizard Use the Management Groups, Clusters, and Volumes wizard to convert an existing standard cluster to a Multi-Site cluster. 1. Start the wizard from the Getting Started Launch Pad. 2. In the wizard, select Existing Management Group and then click Next. 3.

Configuring managers After you have set up your management group, cluster, and sites, you may need to change the manager configuration of your Multi-Site SAN. You also need to add the Failover Manager in all but one type of configuration. Overview The SAN/iQ software automatically starts the regular manager on each storage system when creating a management group. The number of managers started depends on the number of storage systems in the group and whether you create a Multi-Site cluster. In some configurations, a Virtual Manager is also added to the management group. If, however, you plan to use a Failover Manager instead, you must manually install the Failover Manager on a separate server on the network and then add it to the management group as required by the design of your Multi-Site SAN. We recommend using the Failover Manager instead of the Virtual Manager because of its automated failover/failback capabilities. P4000 Multi-Site HA/DR Solution Pack user guide 27

Configuring managers
After you have set up your management group, cluster, and sites, you may need to change the
manager configuration of your Multi-Site SAN. You also need to add the Failover Manager in all but
one type of configuration.
Overview
The SAN/iQ software automatically starts the regular manager on each storage system when creating
a management group. The number of managers started depends on the number of storage systems
in the group and whether you create a Multi-Site cluster. In some configurations, a Virtual Manager
is also added to the management group. If, however, you plan to use a Failover Manager instead,
you must manually install the Failover Manager on a separate server on the network and then add it
to the management group as required by the design of your Multi-Site SAN. We recommend using
the Failover Manager instead of the Virtual Manager because of its automated failover/failback
capabilities.
