Yes, I am sure, as the NEW array wasn’t configured at any more but being out of the data
center makes the removal problematic unfortunately
I think the concept here is that you ADDED a controller to the system.
This can cause the system to enumerate the bus differently so your
old, existing array may now be /dev/sda or /dev/sdc. This will happen
regardless of whether the new array was initialized or not--it's the
order in which the bus was scanned for controllers.
This is also a very good reason to use labels or UUIDs to identify
devices in your /etc/fstab rather than the /dev name as changing the
hardware around is almost guaranteed to change the /dev names and cause
you untold grief.
