<div><p>The Disk Utilization section of the System Report shows the utilization
for each disk.</p>
<p>Changes to this section of the System Report include:</p>
<img src="./delta.gif" alt="Start of change" /><ul><li>The <span class="q">"ASP Rsc Name"</span> and <span class="q">"ASP ID"</span> columns have been removed.</li>
<li>A label has been added at the beginning of each ASP/IASP section that
indicates the ASP ID and ASP Rsc Name. The ASP Rsc Name is printed only when
the DSASPN (ASP resource name) field in the QAPMDISK database file contains
data.</li>
<li>Totals and averages for each ASP/IASP section are printed at the end of
each group of ASP/IASP.</li>
<li>Totals and averages for all disk units are printed at the end of the Disk
Utilization section, as before.</li>
