[OpenIndiana-discuss] How can one test in situ, and under OI, the physical blocksize a SATA disk actually reports??

[Hans J. Albertsson]

I absolutely need such a tool. Don't ask... ah well, to impress a silly 
would-be colleague.

I tried parted and gparted and a few others: but I can't seem to make 
them report what I want to know.

cfgadm, luxadm, ....???
