using cluster resource services. You can also manage them manually.<img src="./deltaend.gif" alt="End of change" /></span></p>
|
||
|
|
<p>There are two ways to have the application takeover IP address associated
|
||
|
|
with an application CRG managed. The easiest way, which is the default, is
|
||
|
|
to let cluster resource services manage the takeover IP address. This method
|
||
|
|
will direct cluster resource services to create the takeover IP address on
|
||
|
|
all nodes in the recovery domain, including nodes subsequently added to the
|
||
|
|
recovery domain. When this method is selected, the takeover IP address cannot
|
||
|
|
currently be defined on any node in the recovery domain.</p>
|
||
|
|
<p>The alternative way is to manage the takeover IP addresses yourself. This
|
||
|
|
method directs cluster resource services to not take any steps to configure
|
||
|
|
the takeover IP address; the user is responsible for configuration. You must
|
||
|
|
add the takeover IP address on all nodes in the recovery domain (except on
|
||
|
|
replicate nodes) before starting the cluster resource group. Any node to be
|
||
|
|
added to the recovery domain of an active CRG must have the takeover IP address
|
||
|
|
configured before being added.</p>
|
||
|
|
<dl><dt class="dlterm">Multiple subnets</dt>
|
||
|
|
<dd>It is possible to have the application takeover IP address work across
|
||
|
|
multiple subnets, although the default is to have all recovery domain nodes
|
||
|
|
on the same subnet. See <a href="rzaigapplicationswitchover2.htm">Enabling application switchover</a> for the
|
||
|
|
steps to configure the application takeover IP address when the nodes in the
|
||
|
|
recovery domain span subnets.</dd>
