No questions...just information for how to translate a Target ID to a SAS WWN
on LSI MPT2 SAS2 controllers under Illumos/Solaris. 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:
scsi: [ID 365881 kern.info] /pci@0,0/pci15ad,7a0@15/pci1000,3030@0 (mpt_sas0):
Log info 0x31120311 received for target 20.
scsi_status=0x0, ioc_status=0x804b, scsi_state=0xc
scsi: [ID 243001 kern.warning] WARNING: /pci@0,0/pci15ad,7a0@15/pci1000,3030@0
(mpt_sas0):
mptsas_handle_event_sync: IOCStatus=0x8000, IOCLogInfo=0x31120303
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.
Run lsituil.i386 as root
(LSIUtil Kit 1.63.zip\Solaris\lsiutil.i386 from
http://www.juhonkoti.net/media/LSIUTIL-1.63.zip )
* Select your MPT device
* e (Enable expert mode in menus)
* 20 (Diagnostics)
* 1 (Inquiry Test)
* 0 (Bus 0)
* XX (Target number from above, Target 20 for me)
* 0 (Lun 0)
* 83 or 80 (SAS WWN and Disk Serial Number respectively)
Output:
VPD Page: [00-FF or RETURN for normal Inquiry] 83
B___T___L Page
0 20 0 83
16 bytes of Inquiry Data returned
0000 : 00 83 00 0c 01 03 00 08 50 01 4e e2 b1 65 f5 d7 P N e
VPD Page: [00-FF or RETURN for normal Inquiry] 80

0010 : 30 34 33 32 38 34 38 39 04328489
The second half of the hex string from 83h is your WWN (50014ee2b165f5d7
above), and ASCII from 80h (WMAY04328489 above) the serial number. 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.
Just thought others might find it useful! Have a great night!
