<p>If

you will be using switchable devices in your cluster, there are additional

requirements than that of a cluster that does not use switchable devices.
|

|
|
To set up a cluster environment that includes switchable devices, care must
|
||
|
|
be taken so that conflicts are avoided across the cluster. See <a href="../rzaly/rzalycreateswitchableiasp.htm">Create
|

<p>iSeries™ Navigator
|
||
|
|
cluster management features a wizard that takes you through the steps to create
|
||
|
|
and start a simple cluster consisting of one or two cluster nodes. Once you
|
||
|
|
have created a one- or two-node cluster, you can add nodes to it. A cluster
|
||
|
|
created and managed in iSeries Navigator can contain as many as four nodes.
|
||
|
|
This wizard will guide you through the steps to specify servers to include
|
||
|
|
and create cluster resource groups. When you are creating a simple cluster,
|
||
|
|
the server you are creating the cluster on must be one of the nodes.</p>
|
||
|
|
<p>To
|
||
|
|
create a simple cluster using the New Cluster wizard in iSeries Navigator,
|
||
|
|
follow these steps:</p>
|
||
|
|
</div>
|
||
|
|
<ol><li><span>In iSeries Navigator,
|
||
|
|
expand <span class="uicontrol">Management Central</span>.</span></li>
|
||
|
|
<li><span>Right-click <span class="uicontrol">Clusters</span>, and select <span class="uicontrol">New
|
||
|
|
Cluster</span>.</span></li>
|
||
|
|
<li><span>Follow the wizard's instructions to create a cluster.</span></li>
|
||
|
|
</ol>
|
||
|
|
<div class="section"><p>Once you have created the cluster, be sure to:</p>
|
||
|
|
<ol><li>Add all of the nodes that you want to include in the cluster. Up to four
|
||
|
|
nodes can be added to a cluster created and managed in iSeries Navigator.</li>
|
||
|
|
<li>Add desired nodes to device domains (for use with switchable hardware
|
||
|
|
groups and independent disk pools).</li>
|
||
|
|
<li>Create and start the switchable resources (switchable device, switchable
|
||
|
|
application, and switchable data).</li>
|
||
|
|
</ol>
|

|

<p>The online help in iSeries Navigator contains step-by-step procedures

on completing these tasks.</p>
