I'm using a Promise VTJ610SS SAS enclosure populated with 16 Samsung
HD203WI 2TB disks. About every 20 minutes, the hard error count
reported by iostat increments by exactly 9 for each disk in the
external enclosure. An identical Samsung disk (c7t27d0) connected to
an internal ICH10R SATA controller shows zero hard errors. Below is
the output from iostat -en:

There are no errors in the syslog to explain why the hard error counts
are increasing. The enclosure is connected to a Nehalem server running
OpenSolaris 2009.06 with an LSI1068E based HBA (SAS3442E-R). I have
another server with identical hardware (except WD RE3 disks instead of
Samsung). and it does not show any iostat errors at all.
Incidentally, I am also seeing the infamous mpt driver timeout lockups
on this system. I would appreciate help in eliminating these hard
errors and solving the mpt driver lockup. I wonder
Thanks,
Daniel Bakken
