I've configured Server 2012 as a poor man's SAN in my lab environment. My virtualization host is connected fine to the iSCSI target I've created. I have 4 NICs, 3 I have reserved for iSCSI traffic. What i can't do however upon installing MPIO on the server is enable iSCSI support under "Discover Multipaths" as I read in a 2008 R2 guide. The option is greyed out.
Research indicated that you cannot enable it until you have an initiator connected to a target. I have that, and still no dice.
Anyone have some ideas I can check? Most of the information out there is for 2008 R2.
