Although I'm a fan of labelling, for some weird reason I had seriously 
weird issues with multipath SAN setups in the last couple of months. I'm 
on holiday at the moment so I can't the logs up but more than once, with 
multipath, labels have caused me too much headache than their worth. In 
one instance the label would latch to one of the individual paths, not 
the multipath and then all hell would break loose. Any suggestions on 
the list are much welcome.

I haven't found a new good practice yet, UUIDs are pretty unwieldly and 
no one can expect to remember one whereas a label of "database" or 
"redo1" or "redo2" are just meaningful and can be parsed by a normal 
human! :)
