Firmware rev 0001, 0002, 0004, and a004 work. Firmware rev 0003 is broken
because someone didn't read or understand the spec. In other words, the
spec is right and FMA follows the spec, the firmware is wrong.
Um, not according to Seagate, form a mail I just received form support:
"Between 0002 and 0003, changes were made to line up with SPC-4
specifications, which changed the order some smart values reported in.
This made a separate value list where the temperature used to go.
Unfortunately, Solaris OS is still looking in the previous place as it
is not SPC-4 compliant, which is causing the issue."
To draw this thread to a close, I was able to verify that the rev 0003
drives were configured with a Reference temperature threshold of 40C.
After a firmware upgrade, some but not all changed to 60C. After
downgrading and then upgrading to 0004 again, they all report 60C. So it
looks like pot luck whether a change of firmware updates the threshold,
but it does change eventually.
"The only possible way to get these drives working properly would be to
apply 0002 firmware, and even that is not guaranteed, as it may not
reset the SMART values. Unfortunately, this is a known issue with
Solaris OS, so if 0002 does not fix the issue, the only other option
would be a different operating system, as we cannot break the
specification."
So the "known issue" is Solaris derived OSs trust the drive data!
I hope this thread saves someone else the pain I've been through with
these drives.
