<h1 class="topictitle1">Scenario: Calculate disk space when moving a disk unit</h1>
|
||
|
|
<div><p>In the following scenario, you are planning to remove a disk unit from
|
||
|
|
a disk pool. Before the disk unit is removed from the source disk pool, the
|
||
|
|
data on the disk unit is copied to the other disk units in the source disk
|
||
|
|
pool. You need to ensure that you have sufficient free space on your source
|
||
|
|
disk pool for this data.</p>
|
||
|
|
<p>Assume that you have 180 GB of used space, 40 GB of free space, the threshold
|
||
|
|
is set to 90%, and the disk unit you are removing from the disk pool has a
|
||
|
|
capacity of 18 GB. </p>
|
||
|
|
<p>Perform the scenario as follows: </p>
|
||
|
|
<ol><li>Using the disk space calculator on the <span class="uicontrol">Capacity</span> tab
|
||
|
|
of the <span class="uicontrol">Disk Pools Properties</span> dialog, enter these values
|
||
|
|
and click <span class="uicontrol">Calculate</span>.<p>A graphical representation of
|
||
|
|
the used and free space on your system appears along with the total disk space,
|
||
|
|
the percent used, and your threshold. </p>
|
||
|
|
</li>
|
||
|
|
<li>From the disk space calculator, select <span class="uicontrol">Remove Disk Space from
|
||
|
|
Disk Pool</span> and enter 18 for the amount. Click <span class="uicontrol">Calculate</span>. <p> The
|
||
|
|
graphical representation is redrawn based on the revised values for used and
|
||
|
|
free space after the 18 GB to be removed is removed from the system. </p>
|
||
|
|
</li>
|
||
|
|
</ol>
|
||
|
|
<p>The percentage of disk space used is now 89.1%. This number just fits under
|
||
|
|
your threshold, but not by much.</p>
