<div><p>To enable cluster resource services, certain attribute settings
|
|
are required in the TCP/IP configuration of your network.</p>
|
|
<p>You must set these attributes before you can add any node to a cluster:</p>
|
|
<ul><li>Set IP datagram forwarding to *YES using the <a href="../cl/chgtcpa.htm"><span class="cmdname">CHGTCPA (Change TCP/IP Attributes)</span> command</a> if
|
|
you plan to use an iSeries™ server as the router to communicate with
|
|
other networks and you have no other routing protocols running on that server.</li>
|
|
<li>Set the INETD server to START. See <a href="rzaigconfiginetd.htm">INETD server</a> for information about starting the INETD
|
|
server.</li>
|
|
<li>Set User Datagram Protocol (UDP) CHECKSUM to *YES using the <span class="cmdname">CHGTCPA
|
|
(Change TCP/IP Attributes)</span> command.</li>
|
|
<li>Set MCAST forwarding to *YES if you are using bridges to connect your
|
|
token ring networks.</li>
|
|
<li>If you are using OptiConnect for <span class="keyword">i5/OS™</span> to
|
|
communicate between cluster nodes, start the QSOC subsystem by specifying
|
|
STRSBS(QSOC/QSOC).</li>
