[OpenIndiana-discuss] Mapping LSI SAS Target numbers to disk SAS WWNs (Log Info 0x31120303)

Sun Mar 17 00:02:55 UTC 2013

there is a way to get this info from mdb... I added a knowledge base article on this at Nexenta a few years ago, lemme see if I can dig it up from my archives...

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 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.
