ISCSI - EqualLogic PS

I have an existing LUN that I am making available to a second server through ISCSI, the initiator picks up the LUN and successfully logs on using chap.  In the disk management tool on Server Manager, you can see the disk, it is not labeled nor does it have a letter assigned, in the bottom pane you can see the disk and the partition, when I right click on the partition for more options all are grayed out except Delete volume and Help.  I have successfully attached this same LUN to a VM using VMWare ISCSI.  What am I missing?

Are the servers configured wiht Microsoft Clustering Service?  If they are not then you cannot connect the same LUN to two different hosts.  This will corrupt your data.  Clustering software allows for the OS to keep track of which server is accessing the data at any point in time, without this you will have issues.

No Clustering service installed or configured, only roles installed on the server are WSUS and IIS.

have you initialized the disk in disk management?

Paulsolov - The LUN will only be accessed by one server at a time.

Charlestasse - I can't do anything with the disk as all options are grayed out, the status shows online, i can bring it offline but thats about it.

Moved data to new LUN and attached that LUN to new server.
