I have a 24 bay Norco case, and I've labeled each physical bay 1 to 24.  After troubleshooting a problem with one of my HBAs, I needed to move the drive that is in bay 18 to bay 7.

 

I would like the device to be labelled "Drive 7" in the Array Devices list, to let me know where to find it if I need to physically move it again.  Unfortunately, I don't see a way to move around drives in the Array Devices list.  After stopping the array, If I remove the Disk 18 device and try to put it in the DIsk 7 slot through the array setup page, then it is warning me that my drive will be formatted.  I could live with this (allowing the array to rebuild from the parity drive) but I think it will still try to emulate the DIsk 18 device, while also reformatting and adding what it thinks is a new Disk 7 device to the array.

 

Is there a way to tell unRAID that the physical drive that it is calling "Drive X" is now "Drive Y" ?

 

This brings up a bigger request that it would be helpful to add notes to each device that are visible in the Array Devices list, so I could, for example, record the physical location of the drive within the case, the date I installed it, etc.  I am currently using a spreadsheet for this housekeeping.  But that is more of an enhancement request.

I would suggest the Server Layout plugin available in CA. It will allow you to assign slot numbers to each disk and shows SN's and other info per disk as well as allowing you to add comments. You can also export all the info so that you have a spare copy of disk assignments.

You can change slots and do a new config and trust parity if using only single parity, with dual parity parity2 will become invalid.
