I have taken to putting a physical label on the outside of the disk 
bracket (I use hot or cold swap disk brackets) with the last four digits 
of the unique ID (usually based on drive S/N). I had managed lots of 
Fibre-Channel drives in a previous life and the _only_ drive ID there is 
the WWN, which better vendors included on the exterior mounting bracket.
