What's strange is that other OS' don't have a problem. I guess this
is just illumos taking more care and *believing* the firmware's

running too hot under illumos.
We first saw this on Solaris 11. Root cause is that the Seagate
firmware change for
FW003 inappropriately sets the reference temperature to the wrong
value. According
to SPC-4
The REFERENCE TEMPERATURE field indicates the maximum reported sensor
temperature in degrees Celsius at
which the SCSI target device is capable of operating continuously
without degrading the SCSI target device's
operation or reliability beyond manufacturer accepted limits.
The FMA disk-transport agent checks for this and, when exceeded, will
fault the drive.
Apparently, this got set to something ridiculously low, like 45C.
NB, in Solaris 11 we can disable the temperature check in
disk-transport.conf. For illumos, we'll need
to make some small changes. Alternatively, you can disable the
disk-transport agent for short-term
relief.
How would I go about disabling the disk-transport agent?
