>Description:
I have two Hewlett-Packard Proliant DL360 servers. One is running 9.0-RELEASE, second is running 8.1-RELEASE. On both there is a problem with thermal control: hw.acpi.thermal.tz0.temperature shows strange temperature:
# sysctl hw.acpi.thermal
hw.acpi.thermal.min_runtime: 0
hw.acpi.thermal.polling_rate: 10
hw.acpi.thermal.user_override: 0
hw.acpi.thermal.tz0.temperature: 8,3C
hw.acpi.thermal.tz0.active: -1
hw.acpi.thermal.tz0.passive_cooling: 1
hw.acpi.thermal.tz0.thermal_flags: 0
hw.acpi.thermal.tz0._PSV: 9,8C
hw.acpi.thermal.tz0._HOT: -1
hw.acpi.thermal.tz0._CRT: 31,3C
hw.acpi.thermal.tz0._ACx: -1 -1 -1 -1 -1 -1 -1 -1 -1 -1
hw.acpi.thermal.tz0._TC1: 4
hw.acpi.thermal.tz0._TC2: 4
hw.acpi.thermal.tz0._TSP: 60

But the temperature in colocation is much more bigger than 8,3C.


>How-To-Repeat:
I believe that a problem is repeatable on HP Proliant DL350 and DL360 servers.
>Fix:
No fix.

 I also looked at DL360e G8 and DL360 G2 and both have exact same value
 of sysctl hw.acpi.thermal as the submitter has posted.
 
 This cannot be a coincidence.
