Is there a way to stop and rename a mounted external drive (DAS set to raid5) so it does not change names every restart linux ubuntu

As title says I have a direct attached storage attached to a Linux machine (that used to be windows). Said raid system started as being called ./Raid and is now after 2 restarts of of the lap top it is now ./Raid2. Is there a way to make it not change names every time I do a restart. I did some looking online but don’t want to...
