I have a small client running ESX Essentials 5.1, have a drive with a per-emptive failure, raid5, no hot spare, I need to take the drive off line, I was thinking, just to cover myself, can I add a 4tb USB drive to the host, what would I need to do for ESX to temporarily see it (until I fail/off line the drive), and it finishes rebuilding, and make this 4tb usb external drive available and formatted as a vmfs partition - so I can hot clone the Guests to the external drive, in case all hell breaks lose.
Or for the cost of the drive - I can just leave it attached and use it, in addition to backup.
Is this doable? If so how? Thanks!!!!
