And the winner is:
	echo "::mptsas -t" | mdb -k
	mptsas_t inst ncmds suspend  power

================================================================================

ffffff0703785000    0     0       0 ON=D0

	The SCSI target information

	devhdl 12, sasaddress 5000c5002128f332, phymask ff,devinfo 401
                 throttle 20, dr_flag 0, m_t_ncmds 0

	devhdl 11, sasaddress 5000c50021295cb2, phymask ff,devinfo 401
                 throttle 20, dr_flag 0, m_t_ncmds 0

mptsas reports the devhdl and you can cross-reference to the SAS address (WWN)

My apologies for cross posting or if this is old hat, but I've been running an LSI SAS2 controller with SATA disks and had my logs fill up with repeated cryptic entries, but never found a troubleshooting strategy until tonight. Under load (scrub) the following will repeatedly show up:

>>> I assumed this was due to a disk failing or a cabling problem (my LSI SAS 9200-16e SAS_2116 has directly cabled WD RE4 SATA disks) but which disk is Target 20? I took the time to label my drive caddies with their WWN to ease trouble shooting, but was never able to figure out how to translate Target ID into a SAS WWN so I narrow down my troubleshooting to a single device....until now.

With that info one can check the cabling path or replace the disk or whatever.  This should work with other LSI SAS2 2008/2118 controllers like the 9200-8e, 9211-8i, etc. Might even work with older SAS1 cards (1068, etc) since lsiutil should also support them.
