I had a problem in one of my DRS/HA Clusters where one ESX 3.0.2 host was unable to see an existing VMFS volume although the volume was in use by other ESX hosts in the cluster, and we confirmed that the SAN LUN zoning was done correctly.
I did have the option in the VI client to add more storage, and then select the LUN, but that would reformat the LUN and I would loose all my existing VM's on that volume.
The fix to this issue was to reset the LUN with "Resignaturing"...

I've been trying to find my local BT exchange to try and determine more or less what speeds I'll get from my Broadband connection. I've stumbled upon the following site that will actually map your exchange out on a Google map relative to your house. It's very handy indeed.
