I have two hard drives that are connected via iSCSI initiator.   They have question marks next to them in 'Computer Management'.
When I right  click and click > Online, I get the attached error message.

The two disks are Online (In Maintenance).
Yet I cannot get these disks online.  

Can anyone help me.

Server 2012 R2, there are no clustered services configured.  
Right now it is just Server 2012 R2, and two iSCSI HDs.

Thankserror message

This error message means that you have Microsoft Failover Cluster role enabled on both servers and cluster service  is configured to use those iSCSI drives as available storage or cluster shared volumes. In order to be able to release those disks you have to go to Failover Cluster Management Console -> Storage and remove them from cluster shared volumes and disks.
