|
|
<div><p>The cluster version defines the level at which all the nodes in
|
|
the cluster are actively communicating with each other.</p>
|
|
<div class="section"><p>Cluster versioning is a technique that allows the cluster to contain
|
|
systems at multiple release levels and fully interoperate by determining the
|
|
communications protocol level to be used.</p>
|
|
<p>To change the cluster version,
|
|
all nodes in the cluster must be at the same potential version. The cluster
|
|
version can then be changed to match the potential version. This will allow
|
|
the new function to be used. The version can only be incremented by one. It
|
|
cannot be decremented without deleting the cluster and recreating it at the
|
|
lower version. The current cluster version is initially set by the first node
|
|
defined in the cluster. Subsequent nodes added to the cluster must be equal
|
|
to the current cluster version or the next level version, otherwise they cannot
|
|
be added to the cluster. </p>

<p><strong>Using iSeries™ Navigator</strong></p>

<p>This requires

|
|
<p>To
|
|
adjust the cluster version of a cluster, follow these steps:</p>
|

</div>
|
|
<ol><li><span>In iSeries Navigator,
|
|
expand <span class="uicontrol">Management Central</span>.</span></li>
|
|
<li><span>Expand <span class="uicontrol">Clusters</span>.</span></li>
|
|
<li><span>Right-click the cluster, and select <span class="uicontrol">Properties</span>.</span></li>
|
|
<li><span>Change the Cluster version to your desired setting.</span></li>
|
|
</ol>
|
|
<div class="section"><p><strong>Using Cluster commands and APIs</strong></p>
|
|
<p>You can also use the
