<h1><img src="images/l_logdr.gif" width="28" height="28">&nbsp;Changing
  the RAID level</h1>
<p>You can change the RAID levels of currently defined logical devices.</p>
<ol>
  <li> In the <a href="cusegui4.htm">Logical devices view,</a> click <img src="images/s_logdr1.gif" width="28" height="20">&nbsp;(logical
    drive). <br>
    <br>
  <li>Right-click <b>Expand or change logical device</b>. The Configuration wizard
    opens with the &quot;Choose RAID level&quot; window.<br>
    <br>
  </li>
  <li> <a href="wselrdcc.htm">Choose a new RAID level</a> for the logical device;
    then, click <strong>Next</strong>. The &quot;Create logical devices&quot; window
    opens. <br>
    <br>
    <p><b><img src="images/note.gif" width="15" height="17"></b> <strong>Note:</strong>
      Only valid RAID level migrations appear in the list. Migration requirements for each RAID level are described <a href="cchgraid.htm">here</a>.<br>
    </p>
  <li> <a href="wcfgldcc.htm">Add the physical drives</a> needed to support the
    new RAID level (if any). Click <strong>Advanced settings</strong> to set the logical device size;
optionally, select a new <a href="cstripe.htm">stripe size</a>. Then,
    click <strong>Next</strong>. The &quot;Configuration summary&quot; window
    opens. <br>
        <br>
	    <p><b><img src="images/note.gif" width="15" height="17"></b> <strong>Note:</strong>
        When you add drives, the migration wizard
        shows the current layout of the data, including the current logical device size. For most migrations,
        you will need to increase the logical device size setting; the default size is not generally adequate once you add drives or segments.<br>
