Hmm. All your disks attached to the same controller and showing
entries in the Illegal Request field ..... what's the common component
between them - the cable?
I guess the common component between them is the power supply. Each
drive has its own SATA cable connected directly to the controller.
Could you look through your msgbuf and/or /var/adm/messages and
find the full text of when these Illegal Request errors were
logged. That
will give an idea of where to look next.
That is the part I can't figure out. Nowhere does it say "Illegal
Request" except when I run iostat -nE.
I found out that the "Illegal Request" count can be incremented on
the ZFS drives by starting a scrub.
For example:
# iostat -nE

Happens every time.
