<h1 class="topictitle1">Evaluate the current configuration</h1>
<div><p>Before you change the disk configuration of your server, it is important
to know exactly where the existing disk units are located in relation to disk
pools, I/O adapters, and frames. The graphical view of iSeries™ Navigator
eliminates the process of compiling all this information by providing a graphical
representation of how your server is configured. You can use the graphical
view to perform any function that is possible through the Disk Units list
view of iSeries Navigator,
with the added benefit of being able to see a visual representation. If you
right-click any object in the table, such as a specific disk unit, disk pool,
parity set, or frame, you see the same options as in the main iSeries Navigator
window.</p>
<p>You can choose how to view the hardware in the Disk Unit Graphical View
window. For example, you can select to view by disk pools, and then select
a disk pool in the list to display only those frames that contain the disk
units that make up the selected disk pool. You can select <span class="uicontrol">Show
all frames</span> to see all frames whether or not they contain disk
units in the selected disk pool. You can also select <span class="uicontrol">Show device
positions</span> to associate disk unit names with the device position
where they are inserted.</p>
<p>You can right-click any highlighted blue disk unit in the graphical view
and select an action to perform on the disk unit. For example, you can select
to start or stop compression on a disk unit, include the disk unit in a parity
set (or exclude it), or rename the disk unit. If the disk unit has
mirrored protection (that is, it is one of a mirrored pair), you can suspend
or resume mirroring on the disk unit. If you right-click an empty disk unit
slot, you can start the Install Disk Unit wizard.</p>
<div class="p">To activate the graphical view, follow these steps:<ol><li>In iSeries Navigator,
expand <span class="uicontrol">My Connections</span>.</li>
<li>Expand your iSeries <span class="menucascade"><span class="uicontrol">server </span> &gt; <span class="uicontrol">Configuration and Service </span> &gt; <span class="uicontrol"> Hardware </span> &gt; <span class="uicontrol"> Disk Units</span></span>.</li>
<li>Right-click <span class="uicontrol">All Disk Units</span>, and select <span class="uicontrol">Graphical
View</span>.</li>
</ol>
</div>
<p>Here is an example of the graphical view in iSeries Navigator. The View by menu
lists several options for viewing disk units. </p>
<img src="rzalb002.gif" alt="This image shows your parity sets within the iSeries Navigator interface." /><p>When you make changes to your disk unit configuration, print the graphical
view for your recovery records. To print the graphical view, on the <span class="uicontrol">Disk
Units Graphical View</span> dialog box, select <span class="menucascade"><span class="uicontrol">File</span> &gt; <span class="uicontrol">Print</span></span><span class="uicontrol"></span>.</p>
<p>To find more information about the graphical view, consult the online help
for disk units. </p>
