Thanks HolyGuacamole
I can see the Edit icon (Pencil) in the All Devices Page, just not the cog for device config for this device, which I assume is one of the devices that this is unavailable.
I had expected that it was using the Storage Manager Server for collecting but had thought I had configured this somewhere, a'la the 'Manage Agent Assignments' Page for Arrays. Thank you for clearing that up. I have enabled debug logging and restarted the poller on the server, now to dig through the output... only 128k lines generated after service start to search
Cheers!
