Temperature sensor on SCSI disks (IBM / Hitachi)

[Oliver Fromme]

Hi,

I have the following SCSI disks in a server:

<IBM DDYS-T18350M S96H>   at scbus0 target 0 lun 0 (pass0,da0)
<IBM DDYS-T18350M S96H>   at scbus0 target 1 lun 0 (pass1,da1)

Searching the mailing lists revealed that IBM SCSI disks
(Hitachi nowadays) have a temperature sensor that can be
queried with a special (prioprietary) command like this:

camcontrol cmd -n da -u 0 -c "4D 0 76 0 0 0 0 0 20 0" -i 32 "s9 i1"

However, I get:  "camcontrol: error sending command".

Any advice?  (I'm using 4-stable, BTW.)

Best regards
   Oliver
