Proper Etiquette For Unmounting a LUN or Detaching a Datastore/Storage Device from multiple ESXi 5.x #EqualLogic #VMWARE

So I was complaining to a group of fellow nerds about how much a pain in the butt it is to ‘properly’ remove a LUN from ESX… you know so that you don’t cause an APD incident (you know, accidentally freeze up all of your virtual machines…)

So now I’m having fun recreating my volume with vmfs5.

I didn’t get to ‘pull’ it using the ESX server, instead I installed the standalone converter 3.0.3 of course on the physical machine. I see some warnings that the converter is ignoring bad blocks and the virtualization goes smoothly. So there you go
