See diskinfo(1M), for example:


$ diskinfo -T bay -o Rc -h

In your case you probably will have to put a configuration in place for your
disk slots (on Oracle's HW it works out of the box) - go to
support.oracle.com and look for the document:

	How To : Selecting a Physical Slot for a SAS Device with a WWN for
an Oracle Solaris 11 Installation [ID 1411444.1]




ps. there is also zpool status -l option which is cool:

$ zpool status -l cwafseng3-0
  pool: pool-0
 state: ONLINE
  scan: scrub canceled on Thu Apr 12 13:52:13 2012
config:

        NAME
STATE     READ WRITE CKSUM 
        pool-0

          raidz1-0
