    <description>&lt;P&gt;From the RAID log, drive in slot 5 failed and caused the VD offline. First of all, you should not mix SATA and SAS drives in the same enclosure. See &lt;A href="http://www.intel.com/support/motherboards/server/sb/CS-030795.htm"&gt;http://www.intel.com/support/motherboards/server/sb/CS-030795.htm&lt;/A&gt; &lt;A href="http://www.intel.com/support/motherboards/server/sb/CS-030795.htm"&gt;http://www.intel.com/support/motherboards/server/sb/CS-030795.htm&lt;/A&gt;. Main reason is that SAS drives have higher RPM and thus generates more vibration, which may cause SATA drives performance degrade, or even offline. &lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Also please make sure your &lt;A href="http://downloadcenter.intel.com/Detail_Desc.aspx?agr=Y&amp;amp;DwnldID=20174"&gt;http://downloadcenter.intel.com/Detail_Desc.aspx?agr=Y&amp;amp;DwnldID=20174&lt;/A&gt; RAID firmware and &lt;A href="http://downloadcenter.intel.com/Detail_Desc.aspx?agr=Y&amp;amp;DwnldID=20245"&gt;http://downloadcenter.intel.com/Detail_Desc.aspx?agr=Y&amp;amp;DwnldID=20245&lt;/A&gt; backplane firmware are updated. &lt;/P&gt;</description>
