I have a HP Proliant DL380 G6 Server with x2 HP FC1142SR 4GB PCI-e FC cards installed running Windows Server 2008 R2. Compellent SAN attached storage has been successfully presented to the server and test data copied to the SAN attached disks within Windows. For FC resiliency I've installed the feature Microsoft MultipathIO onto the server. I've configured MultipathIO as per MS Technet article http://technet.microsoft.com/en-us/library/ee619778(WS.10).aspx
. In the MPIO properties dialog box I've added the device hardware ID's "COMPELNTCompellent Vol" & "COMPELNTCompellent Vol1" after a reboot the MPIO tab has appeared within the SAN attached disks in windows disk management. Within the MPIO tab the device is only showing 1 path and not 2 as I would expect. I've attempted testing resiliency by removing one of the fibre cables and the failover does not work as some of the SAN external attached disks disappear from Windows. I've tried MPIO policies Round Robin and Fail Over only both without success.
Does anyone know how to configure Microsoft MultipathIO using compellent storage? Any help will be much appreciated.
