could you please confirm whether the devices exhibiting the problem
are internal to your host, or connected via jbod. And if via jbod,
please confirm the model number and cables.

I have a SuperMicro X8DTN motheboard and an LSI SAS3081E-R, which is
firmware 1.28.02.00-IT. I have 24 drives attached to the backplane of
the system with a single mini-SAS cable probably not even 18 inches
long. All the drives are WD RE4-GP.

OpenSolaris, snv_130, is running on VMWare, but I am using PCI
passthrough for the LSI card.

It turns out the the mpt_sas HBAs are affected the same way:


Hi Maurice,
this is very interesting to note. I'll pass the info along to
the relevant team (they're in Beijing, so away for another few
days due to Spring Festival).


I have identified the culprit is the Western Digital drive 
WD2002FYPS-01U1B0. It's not clear if they can fix it in firmware, but 
Western Digital is replacing my drives.
