That is a solution for the case that you want to keep both
disks running in the system. If you just want to make one
disk (b) available in order to swap it when the master disk
fails (w), then labels are fine.

I'm not sure what your main purpose of cloning the disks
was. Two options:
        a) keep two disks in sync, so you can use your
           backup disk when the working disk fails and
           needs to be extracted
        b) make a clone of your working disk so it can
           be placed into another system

The label doesn't need to be changed when the disk in question
is placed into another system. Labels work independent from
the different settings you might find in different computers,
such as different device names (due to different position on
the controller).
