That's good to know. It would be interesting to know if the smartctl
command in question can actually make it through a solaris system, and
on what disk driver. AHCI and mpt are different because one is SATA
framework and one isn't. I wonder also if SAS expanders cause any
problems for smartctl?
So, using latest SVN of smartmontools:
AHCI reads work, writes don't (could be the drive - a WDC
WD3200KS-00PFB0), must specify -d sat,12 to get anything:
root:gandalf 0 # ./smartctl -d sat,12 -l scterc,70,70 /dev/rdsk/c9t0d0p0
smartctl 5.40 2010-05-12 r3104 [i386-pc-solaris2.11] (local build)

SCT Error Recovery Control:
Read: 57345 (5734.5 seconds)
Write: 57345 (5734.5 seconds)
mpt nothing works (and I see reports from Windows that it should with
this disk, a ST31500341AS with CC1H firmware):
root:gandalf 1 # ./smartctl -d sat,12 -l scterc /dev/rdsk/c7t9d0
