On CMs other than CM 1 (I have 3 total), when I look in Disk Management in Windows, it is showing a bunch of single 300GB drives that are offline. I have created my LUNs and VDs through the management console, installed 2008 R2 on all three hosts, and have been able to create about a dozen VMs. So everything seems to be working just fine, but why are the other 2 CMs showing these single drives in disk management? If I remove the second controller, they disappear.. Intel's MPIO IS installed all all three CMs.</P><P></P><P>I only noticed this after attempting to connect a SAN via iSCSI to these 3 CMs.</P> Thu, 05 Jul 2012 14:37:02 GMT https://community.intel.com/t5/Intel-Xeon-Processor-and-Server/Modular-Server-and-Second-Controller-Issue/m-p/380662#M8096 SBerg6 2012-07-05T14:37:02Z https://community.intel.com/t5/Intel-Xeon-Processor-and-Server/Modular-Server-and-Second-Controller-Issue/m-p/380663#M8097 <P>When you add a second SCM, you must update the drivers for Windows so it can read the storage pools properly.</P><P></P><P><A href="http://www.intel.com/support/motherboards/server/sb/CS-029441.htm">http://www.intel.com/support/motherboards/server/sb/CS-029441.htm</A> Intel� Modular Server Systems — Special instructions for installing dual Storage Control Modules</P> Tue, 10 Jul 2012 22:52:14 GMT https://community.intel.com/t5/Intel-Xeon-Processor-and-Server/Modular-Server-and-Second-Controller-Issue/m-p/380663#M8097 Daniel_O_Intel 2012-07-10T22:52:14Z
