Thank you. Yes, I saw that KB and I was able to get "vim-cmd vmsvc/device.diskaddexisting" to work. However, if possible I'd rather do this with remote CLI commands. If I can avoid it, I don't want to have to activate ssh on the ESXi host and log in to run vim-cmd commands.
I'm running vmkfstools from a vMA. Know of any remote CLI command that hot-adds virtual disks?
