It also allows you to create and manage clusters, CRGs, cluster administrative domains, and resources.<img src="./deltaend.gif" alt="End of change" /></p> <div class="important"><span class="importanttitle">Important:</span> <img src="./delta.gif" alt="Start of change" />The iSeries Navigator cluster management interface does not contain all of the capabilities provided by cluster resource services. While iSeries Navigator provides many functions necessary to configure and manage a cluster, be aware that there are some capabilities that are only available through the cluster commands and APIs, or perhaps through a cluster middleware IBM Business Partner application, depending on the particular application. For example, the iSeries clustering architecture supports up to 128 nodes in a cluster, however the iSeries Navigator interface only supports up to four nodes in a cluster. iSeries Navigator cluster management features a wizard which steps you through the creation of a simple, four-node cluster. If your clustering needs exceed this, you should consider using the IBM cluster commands and APIs or cluster middleware IBM Business Partner products. <img src="./deltaend.gif" alt="End of change" /></div> <p><img src="./delta.gif" alt="Start of change" /> You can also use iSeries Navigator to perform other cluster-related tasks. Some of these tasks include:<img src="./deltaend.gif" alt="End of change" /></p> <ul><li>Adding a node to an existing cluster</li> <li>Adding a switchable devices to a cluster</li> <li>Adding a switchable applications to a cluster</li> <li>Adding a switchable data group to a cluster</li> <li>Change the role of nodes in the recovery domain</li> <li>Changing the cluster description</li> <li>Deleting a cluster</li> <li>Starting clustering</li> <li>Stopping clustering</li> <li>Viewing messages about cluster activity</li> <li><img src="./delta.gif" alt="Start of change" />Creating a cluster administrative domain<img src="./deltaend.gif" alt="End of change" /></li> <li><img src="./delta.gif" alt="Start of change" />Adding a monitored resource entry<img src="./deltaend.gif" alt="End of change" /></li> </ul> <p><img src="./delta.gif" alt="Start of change" />For a complete list cluster-related tasks that are available in iSeries Navigator, see the online help for clusters.<img src="./deltaend.gif" alt="End of change" /></p> <div class="note"><span class="notetitle">Note:</span> The iSeries Navigator cluster management interface does not support logical object replication.
