  Manually rebuilding a failed drive</h1>
<p> Use this action to rebuild a <a href="gcrt.htm">degraded</a> logical device
  when a physical drive in the pool is <a href="gddd.htm">failed</a>.

  Normally,
    the controller rebuilds a logical device when it detects the removal
    and reinsertion of a drive that is part of an pool. Use this operation to force
    the rebuild to begin immediately, without physically removing and replacing
  the disk drive.


  </p>
<p><img src="images/note.gif" width="15" height="17"><strong> Note:</strong> The
  controllers can rebuild RAID level-1, level-5,
  level-10, and level-50 logical devices. They cannot, however,
  rebuild RAID level-0 logical devices because RAID level-0 is not redundant.</p>
<p>Complete the following steps to manually rebuild a failed drive:</p>
<ol>
  <li>In the <a href="cusegui4.htm">Physical devices view</a>, click <img src="images/s_pd_ddd.gif" alt="failed physical drive" width="22" height="15" align="absbottom">
    (failed physical drive).<br>
    <br>
  </li>
  <li> Right-click <b>Rebuild drive</b>.<br>
    <br>
  </li>
  <li>Click <b>Yes</b><strong> </strong>to confirm. <br>
    <br>
    <img src="images/note.gif" width="15" height="17"><strong> Note:</strong>
    During the rebuild operation, the failed drive enters the rebuild state and
    the logical device remains degraded until the rebuild operation is completed.<br>
  </li>
</ol>
