<div><p>IBM<sup>®</sup> offers
|
|
a cluster management interface that is available through iSeries™ Navigator
|
|
and accessible through Option 41 (<span class="keyword">i5/OS™</span> -
|
|
HA Switchable Resources).</p>
|
|
<p><img src="./delta.gif" alt="Start of change" />This interface allows you to create and manage a cluster
|
|
that uses switchable independent disk pools (switchable independent ASPs)
|
|
to ensure data availability. 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>
