not exactly per drive but nmon command ^ gives you the stats of your HBAs. The 
only thing that does better that that is the TSM server instrumentation (instr 
begin, instr end f=<file>), but I wouldn't run that for very long periods of 
time.

I think your options are limited to nmon and good old sar.

topas and nmon have merged... they are now one and the same.
