Hi Steven,  glad to help you.  Unfortunately i am not in front of a console and i am not so familiar with UniSphere to help you. It is quite different from the SMC. Also i don't remember the commands to tell you how to do it via CLI.  Anything you want i will try to answer you ASAP.
So we are in the middle of our first EMC implementation, we have (over seas) professional services working with us. They created a few LUNs in a test pool, we verified we were able to connected them to our VMware environment. The services engineer attempted to move volumes to a new storage group, and now our VMware environment has lost all connectivity to those LUNs.  I see a few issues.  1. How do you delete unwanted storage groups?  The storage group makes you keep one volume in it, and you can't delete it with the volume present.  2. Their solution for this issue was to delete the LUNs and start over This is not a viable solution when in production  Any one have experience with this?  Thank you kindly, Steven
