--- Comment #28 from Peter Eriksson <pen@lysator.liu.se> ---
Actually, with

  hw.ciss.nop_message_heartbeat=3D"0"

my first test ended with=20

  ciss2: ADAPTER HEARTBEAT FAILED

and then things deadlocked.



With:

  hw.ciss.nop_message_heartbeat=3D"1"

and if I didn't provoke it with the "sesutil show" then all disks got detec=
ted
correctly and it failed the two dead ones after a while and all zfs filesys=
tems
got mounted. The server has now been running for 10 hours without problems.

(Going to remove the problem disks later today)

hw.ciss.verbose =3D "1"
hw.ciss.nop_message_heartbeat =3D "1"
hw.ciss.base_transfer_speed =3D "1200000"
