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 Option 41 (HA Switchable Resources) to be installed and licensed.</p> <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 following to adjust the cluster version of a cluster:</p> <ul><li><a href="../cl/chgcluver.htm"><span class="cmdname">Change Cluster Version (CHGCLUVER)</span> command</a></li> <li><a href="../apis/clcntchgcv.htm"><span class="apiname">Adjust Cluster Version (QcstAdjustClusterVersion)</span> API</a></li> </ul> </div> </div> <div> <div class="familylinks"> <div class="parentlink"><strong>Parent topic:</strong> <a href="rzaigmanage.htm" title="This topic contains information that covers some of the tasks that involve managing your clusters.">Manage clusters</a></div> </div> <div class="relconcepts"><strong>Related concepts</strong><br /> <div><a href="rzaigplanclusterversions.htm" title="A cluster version represents the level of function available on the cluster.">Cluster version</a></div> <div><a href="rzaigtroubleshootcommonproblems.htm" title="Lists some of the most common problems that can occur in a cluster, as well as ways to avoid and recover from them.">Common cluster problems</a></div> </div> <div class="reltasks"><strong>Related tasks</strong><br /> <div><a href="rzaigmanagedeletecluster.htm" title="When you delete a cluster, cluster resource services will be ended on all active cluster nodes and they will be removed from the cluster.">Delete a cluster</a></div> </div> </div> </body> </html>
