With power off, remove the physical drives that are included in one of the new arrays.
IMPORTANT
If you do not remove one of the arrays, the operating system will
be unable to distinguish between the two new arrays after the
operating system has been restarted (next step) because the
arrays will be identical.
13.
Restart the operating system.
