shrink equllogic volume - datastore inaccessible on host

I have a Dell Equallogic PS 6500 array.  I needed to resize a few volumes (no critical data). I snapshot the volume and resized it to a lower size after taking it offline.  The Equallogic Gui shows the correct shrunk size.  However, ESXi (dell R630 two hosts) both show the datastore as inaccessible. I have rescanned and restarted the server and the DS does not come back.  Im at a loss and not sure what to do next or if i missed something that needed done on the hosts themselves first.

Andrew,
The LUN is connected. In the screen shot its the one that is 75GB and the path is active (ISO).

Andy,
It was resized using the CLI directly on the equalogic via ssh.User generated image
I would concur with andyalder you've broke and corrupted it!

There is a LUN, and the VMFS partition on/in the LUN (datastore), you've just shrunk the LUN, but you didn't shrink the VMFS partition first, so you broke it!

Restore time, and I would destroy the LUN and re-create of the desired size.
Thank you for the reply. Im glad it was a non critical LUN.
Is there a shrink option in VMware Andrew? All the docs I find that say it can't be done are for 5.5 and previous.
VMFS can be shrunk, but it's not supported, and it's a process which needs to be done, before chopping off the LUN
