<p>服务器开机的时候提示如下：</p>
<blockquote><p>Your battery is either charging, bad, or missing; and you      <br />have Virtual Drives (VD) configured for write-back mode.       <br />Because the battery is currently charging, these VDs will       <br />actually run in write-through mode until the battery is       <br />fully charged or replaced if it is bad or missing.</p>
</p>
</blockquote>
<p>说明参见：<a title="http://www-900.ibm.com/cn/support/viewdoc/detail?DocId=XLIU-7FYDNQ" href="http://www-900.ibm.com/cn/support/viewdoc/detail?DocId=XLIU-7FYDNQ">http://www-900.ibm.com/cn/support/viewdoc/detail?DocId=XLIU-7FYDNQ</a></p>
<p>解决办法，充电就行了。</p>
<p>&#160;</p>
<p>另外关于raid卡电池：</p>
<p>现代的raid卡电池是用于断电时将缓存保存到硬盘上的，所以没电也没关系。</p>
<p>参考：</p>
<p><a title="http://support1.ap.dell.com/cn/zh/forum/thread.asp?fid=19&amp;tid=210060" href="http://support1.ap.dell.com/cn/zh/forum/thread.asp?fid=19&amp;tid=210060">http://support1.ap.dell.com/cn/zh/forum/thread.asp?fid=19&amp;tid=210060</a>    <br /><a title="http://www.5dmail.net/bbs/thread-177127-1-5.html" href="http://www.5dmail.net/bbs/thread-177127-1-5.html">http://www.5dmail.net/bbs/thread-177127-1-5.html</a></p>
<p>&#160;</p>
<p>另外还有一篇关于raid的帖子也很有价值：</p>
<p><a title="https://www-900.ibm.com/cn/support/forum/app/tscforum/topic?tid=184300" href="https://www-900.ibm.com/cn/support/forum/app/tscforum/topic?tid=184300">https://www-900.ibm.com/cn/support/forum/app/tscforum/topic?tid=184300</a></p>
<p>也就是说，raid信息存在了磁盘里，更换raid卡就可以自动重建了。这样raid卡坏掉也没关系了。</p>
<p>当然，不是每个卡都这样的。</p>
