Cannot add LUN to more than one host

Hi all,

Esxi 5.1 EMC VNX on firbe.

IM trying to add a second LUN to my hosts. The host finds the LUN but when I add it I get the following screen (attached)

I choose the top option but nothing gets added?

very odd....

if the LUN is blank, I would delete it, and re-create a new LUN.

Is this a brand new LUN, never been used before ? (and it has no data).

If so, it's Format the disk - Create a new datastore.

You are adding new storage. e.g. new LUN and datastore.
