Oh. I didn't notice the lack of colon.

No, you can't just split on a comma, that's a legitimate part of either the 
name or unit address. That should be:


Both the nodename and unit address are allowed the have commas (e.g., 
"QLGC,isptwo" is the name of a SCSI adapter from Qlogic, and "@0,1" means 
target zero, unit 1).

The question is why are you missing both the unit address and the colon 
separator for the argument. The right answer is to make sure you're following 
the path resolution in section 4.3.1 in 1275.
