By adding new hosts to an existing host group, you can better manage and distribute the load on
your applications and resources. You can access existing volumes whenever you are ready to allocate
them in an existing host group.

The following figure illustrates the process of adding a host to create clustered-host storage in a system.

Defining clustered-host storage

You can create clustered-host storage by allocating volumes to a new host within an existing host
group (also known as a host cluster).

Creating clustered-host storage involves allocating new or additional volumes to a new host that has
been added to an existing host group, new LUN paths being set to the new host, and the WWN of
this host being added to an existing host group.

Prerequisites

Tasks to complete beforehand:

Discover (and register) new hosts.

Allocate volumes to existing hosts.

1.

On the Resources tab, click Hosts, and select All Hosts to list the hosts by OS type in the
Application pane.

2.

From the list of hosts, select one or more existing hosts (or volumes allocated to these hosts).
