<p>The Add Cluster Node Entry (QcstAddClusterNodeEntry) API is used to add a
node to the membership list of an existing cluster.</p>
<p>If the "Start Indicator" parameter is set to 0, the node that is being added
will have a status of New and Cluster Resource Services will not be started on
that node. The <a href="clcntstcn.htm">Start Cluster Node
(QcstStartClusterNode) API</a> can be called from a program running on one of
the active nodes in the cluster to start Cluster Resource Services on a node
that does not have a status of Active.</p>
<p>If the "Start Indicator" parameter on this API is set to 1, Cluster Resource
Services will be started on the node that is being added. If Cluster Resource
Services is successfully started, the status for the added node will be set to
Active. If the Cluster Resource Services cannot be started, the status of the
added node will be set to New.</p>
<p>During the activation of Cluster Resource Services, the allow add to cluster
(ALWADDCLU) network attribute is checked to see whether the node being added
should be part of the cluster and whether to validate the cluster request
through the use of X.509 digital certificates. If validation is required, the
requesting node and the node being added must have the
<img src="delta.gif" alt="Start of change">software required for
<a href="..//rzain/rzainplanssl.htm">
SSL</a> installed on the systems.
<img src="deltaend.gif" alt="End of change">
</p>
<p>The following conditions apply to this API:</p>
<ul>
<li>A node cannot add itself to a cluster. It must be added from a node in the
cluster that has a status of Active. If Cluster Resource Services has not been
started on any of the nodes in the cluster, this API must be called from a
program running on the node where the cluster was originally created, and the
start indicator must be set to 0.</li>
<li>The node being added to the cluster must not already be a member of this or
any other cluster. A node can be a member of only one cluster.</li>
<li>If the start indicator is set to 1, the node must be IP reachable (TCP/IP
active and the INETD server started).</li>
<li>The API will fail if any node in the cluster has a status of
Partition.</li>
<li>If the start indicator is set to 1, the potential node version of the node
being added must be equal to the current cluster version or up to one level
higher than the current cluster version. The potential node version and the
current cluster version can be retrieved by using the <a href=
"clcntlstci.htm">List Cluster Information (QcstListClusterInfo) API</a>. The
potential node version can also be retrieved by using the <a href=
"clcntrtvci.htm">Retrieve Cluster Information (QcstRetrieveClusterInfo)
API</a>.</li>
</ul>
<p>This API operates in an asynchronous mode.
See <a href="clust1a3.htm#HDRASYMOD">Behavior of Cluster Resource Services APIs</a> for
more information.</p>
<p><strong>Restriction:</strong> This API cannot be called from a cluster
resource group exit program.</p>

has completed on all active nodes in the cluster. See the <strong>Usage
Notes</strong> section of this API for a description of the data that is placed
on this queue. This is a 20 character field. The first 10 characters contain
the user queue name and the second 10 characters contain the user queue library
name. No special values are supported. QTEMP, *LIBL, and *CURLIB are not valid
for the library name. The attributes of this user queue must be keyed.</p>

<h3>Field Descriptions</h3>
<p><strong>Cluster interface address.</strong> The cluster interface address is
an IP address that is used by Cluster Resource Services to communicate with
other nodes in the cluster. The address is in dotted decimal format and is a
null-terminated string.</p>
<p><strong>Note:</strong> Cluster Resource Services uses existing IP interfaces
configured for an iSeries. See <a href="../rzai2/rzai2kickoff.htm">TCP/IP</a> for
instructions for configuring IP interfaces on the iSeries. The IP addresses
defined as cluster interface addresses can be used by other applications. If an
IP address is reconfigured through the TCP/IP configuration functions, the <a
href="clcntchgcne.htm">Change Cluster Node Entry (QcstChangeClusterNodeEntry)
API</a> should be used to make the corresponding change to the cluster
interface address. A mismatch will cause cluster errors to occur.</p>
<p><strong>Node id.</strong> A valid simple name that uniquely identifies the
node.</p>
<p><strong>Number of cluster interfaces.</strong> The number of IP interfaces
associated with a cluster node. It is limited to 1 or 2 entries only.</p>
<p><strong>Offset to first cluster interface entry.</strong> The offset from
the beginning of the structure to the first cluster interface address
entry.</p>
<h3><a name="usage_notes">Usage Notes</a></h3>
<p><strong>Results Information User Queue.</strong> Asynchronous results are
returned to a user queue specified by the Results Information parameter of the
API. See <a href="clust1a4.htm">Cluster APIs Use of User Queues</a> and <a
href="clust1a5.htm">Using Results Information</a> for details on how to create
the results information user queue, the format of the entries, and how to use
the data placed on the queue. The data is sent to the user queue in the form of
a message identifier and the substitution data for the message (if any exists).
The following identifies the data sent to the user queue (excluding the message
text).</p>
