We are running our virtual network on ESX 4.1. I've run into an issue with one of our VMs (running Windows 2008R2). One of the drives on the server is a Raw mapped LUN. All the files have been removed from this drive and it is no longer needed for the server. I would like to remove this raw LUN from the server and make it available to the sans for creating a new virtual disk.
My question is, what are the steps I need to follow to remove it from the server, without causing problems for the server.
