<div><div class="section"><p>Because virtual images are stored on your disk units, they can
|
|
quickly use disk space. It is essential that you determine whether you have
|
|
enough disk space. The smallest allowable size for a optical image file volume
|
|
is 48 MB. The largest allow able size is 16 GB.</p>
|
|
<p>To determine how much
|
|
disk space you have, do the following:</p>
|
|
</div>
|
|
<ol><li class="stepexpand"><span>In iSeries™ Navigator,
|

expand <span class="menucascade"><span class="uicontrol">My Connections</span> > <span class="uicontrol">your iSeries

displays the used space, free space, total capacity, threshold, and percentage

make the volumes is 650 MB.</span></li>
