Using VMWare ESX For ZCS Test Servers - How-To
My Version of Vmware ESX does not have a cloning option - I was actually given the ESX box rebuilt. So here's what I did to 'clone' an image the manual way.
I just did this and I plan on going through it and improving it once I have time. I believe the hard coded reference to the volumes could use the sym-link for the path - /vmfs/volumes/Storage vs. /vmfs/volumes/4bbaf57f-6230127f-d432-00101849e4af .
