Okay, just in case someone has the same issue.  Like I said, the clone wizard allocates drives and creates a raid group when you run it. Apparently on the VNX series, you don't allocate hot spares, you just leave enough unbound drives around to cover your array. My policy is 1:30 drives.  Anyway, I was able to figure this out. I had deleted all of the clone references, but had missed one that was hard to find. I did the following in the GUI after choosing my device: You should see the entries there, and you can delete them. This isn't the most obvious place, so it's easy to miss.
Hey there,  VNX5200.  I wanted to check out clones, so I created a test to see how it worked. I ran the clone wizard and everything seemed to go well.   Unfortunately, I started getting hot spare policy errors. Seems like the process of creating the clone allocated some of my unbound drives to a RAID group for the clone.   I deleted the clones, but I can't delete the associated RAID group or the private LUNs.   I want to get my hot spares back.  Thanks,   Drew Morone
Created a clone. Made a mess. Can't delete private LUNS
