This helps you ensure that your system has sufficient disk storage for the changes.</p> <p>You can use the <a href="rzalbcalcspace1.htm">Disk space calculator</a> to determine if your disk pool contains sufficient storage space to perform changes. To use the calculator, you need to know how much free space and used space exists in the disk pool. </p> <p>To view your disk pool configuration</p> <ol><li>In iSeries™ Navigator, expand <span class="menucascade"><span class="uicontrol">Disk Units</span> > <span class="uicontrol">Disk Pools</span></span>.</li> <li>Right-click the source disk pool you want to view and select <span class="uicontrol">Properties</span>.</li> <li>Select the <span class="uicontrol">Capacity</span> tab. <p>The <span class="uicontrol">Capacity</span> tab displays the used space, free space, total capacity, threshold, and percentage of disk space used for the disk pool. </p> </li> <li>Note the used space, free space, and the threshold from the <span class="uicontrol">Capacity</span> tab. </li> <li>Enter the used-space value and free-space value in the calculator. </li> <li>If you want to use the threshold value, enter the threshold value in the calculator. <p>The calculator will warn you if your disk use exceeds your threshold.</p> </li> </ol> <p>The calculator uses JavaScript™ to function.
