<h1 class="topictitle1">Detach mirror copy</h1>
|
||
|
|
<div><p>If you are using <a href="rzalygeographicmirror.htm">geographic
|
||
|
|
mirroring</a> and want to access the mirror copy to perform save operations
|
||
|
|
or data mining, or to create reports, you must detach the mirror copy from
|
||
|
|
the production copy. You detach the mirror copy by accessing the production
|
||
|
|
copy of the disk pool.</p>
|
||
|
|
<div class="note"><span class="notetitle">Note:</span> When you reattach the detached mirror copy, a complete synchronization
|
||
|
|
is required between the production and the mirror copies. Synchronization
|
||
|
|
can be a lengthy process.</div>
|
||
|
|
<div class="p">To detach the mirror copy, follow these steps:<ol><li>It is recommended that you make the independent disk pool unavailable
|
||
|
|
to ensure the production copy is not altered while the detach is being performed.
|
||
|
|
See <a href="rzalymakediskpoolunavailable.htm">Make the independent
|
||
|
|
disk pool unavailable</a>. </li>
|
||
|
|
<li>In iSeries™ Navigator,
|
||
|
|
expand <span class="uicontrol">My Connections</span> (or your active environment).</li>
|
||
|
|
<li>Expand the server that owns the production copy of the disk pool from
|
||
|
|
which you want to detach the mirror copy.</li>
|
||
|
|
<li>Expand <span class="menucascade"><span class="uicontrol">Configuration and Service</span> > <span class="uicontrol">Hardware</span> > <span class="uicontrol">Disk Units</span> > <span class="uicontrol">Disk Pools</span></span>.</li>
|
||
|
|
<li>Right-click the production copy of the <span class="uicontrol">Disk Pool</span> you
|
||
|
|
want to detach and select <span class="menucascade"><span class="uicontrol">Geographic Mirroring</span> > <span class="uicontrol">Detach Mirror Copy</span></span>.</li>
|
||
|
|
<li>If <span class="menucascade"><span class="uicontrol">Geographic Mirroring</span> > <span class="uicontrol">Detach
|
||
|
|
Mirror Copy</span></span> cannot be clicked, because it is disabled.
|
||
|
|
The mirror copy is not in sync with the production copy, so geographic mirroring
|
||
|
|
must be resumed, the disk pool varied on, and production and mirror copies
|
||
|
|
synchronized before the mirror copy can be detached. </li>
|
||
|
|
</ol>
|
||
|
|
</div>
|
||
|
|
<p>Before you make the detached mirror copy
|
||
|
|
available, you should <a href="../cl/crtdevasp.htm">create
|
||
|
|
a second, unique device description</a> for the independent disk pool that
|
||
|
|
differentiates it from the production copy. A separate device description
|
||
|
|
for the mirror copy prevents two instances of the same database in the network.
|
||
|
|
It will also simplify work done outside of iSeries Navigator. Use the detached mirror
|
||
|
|
copy device description to make the detached mirror copy available. </p>
