I need to create a bunch of LUNs to provide storage for VMWare ESX hosts. The current plan is to create each LUN inside its own volume. I've created one volume and LUN and mapped it whereupon an ESX box can see the LUN and format it. No problems as such BUT I get an error (seen via the dmf/operations manager view) saying "Volume Full". The volume is indeed full -- by design!
Is there a way of saying "yes I know this volume is full and it's not an error", please?

In Operations Manager, you can change thresholds for individual volumes:
Alternatively, you can use the DFM command line:

An alternative is also just thin provisioning your LUNs. If you don't space reserve your LUN's and have no guarantees on your volumes, then you don't really use any extra space just making the volumes 10-20% larger than your luns. In the end, it can really make life easier because you really only have to watch the aggregate filling levels. The added value is, of course, that you can use the blocks that have been ordered and "reserved" with full provisioning for other things.
Just a thought. It made my life a lot easier.
