March 22, 20242 yr Hi, I want to reorganize the drives in my Unraid computer, connecting them to other cables for instance, so I wonder: How are identified the drives by Unraid, the drives themselves or the connector they're attached? If I change their position, will Unraid recognize automatically who they are, or will I be able to manually reassign each disk to it's unraid's device number, or ... ?
March 22, 20242 yr Community Expert Solution this depends a bit on the used controller hardware. Usually UNRAID uses the unique serial number of the disk to find it back again. So you can move the drives anywhere and their meaning stays the same. But some strange (mostly external USB cases) controllers catch this call and present their own ideas of the number. This, of course, leads to trouble when the drive is moved later on because UNRAID has stored the fake number and now gets the real one, or another fake... Luckily these cases are rare, so usually, yes, you can swap them freely and they still will be recognized. (beware to stop the array before you move them!!! else you will run into big problems...)
