temperature warning messages

We have several DS10s bought couple of months ago. they are giving out warning messages like this every 2~6 hours:

Broadcast Message from root@sms30 (???) at 5:47 ...
The system temperature is high. Possible reasons are
a clogged air filter or a high ambient room temperature.
The system will shut down in 14 minutes and 0 seconds..

Broadcast Message from root@sms30 (???) at 5:47 ...

The system is now operating at a safe temperature.
The system shut down will be aborted.

Broadcast Message from root@sms30 (???) at 7:30 ...

The system temperature is high. Possible reasons are
a clogged air filter or a high ambient room temperature.
The system will shut down in 14 minutes and 0 seconds..

These DS10s just only had OS(5.1B-1) installed, and the fans are good, air way is not blocked, room temperature is reasonable. I just don't know why they are all giving out these messages. Is hardware problem possible?
Should I just contact the vendor?

By the way, is there any temperature monitoring tools other than ">>> show power " ?

Thanks.

Re: temperature warning messages

thanks Michael for the quick response.

here's the result of sysconfig -q envmon:
envmon
env_current_temp = 35
env_high_temp_thresh = 60
env_fan_status = 0
env_ps_status = 0
env_supported = 1

Re: temperature warning messages

Sure. I'll try to write a simple sript that cathes temp every couple of minutes.

Re: temperature warning messages

hi,

our solution to this problem is to maintain the temperature in the server room.

Re: temperature warning messages

I found shutdown_temp as a SRM environment variable within the "show" output of my DS10.

>>>show shutdown_temp
shutdown_temp 60

Re: temperature warning messages

I spoke to local field service about this problem just yesterday. He found a document somewhere that says this is a known problem with DS10s running V5.1B PK3. Fix will be provided in PK4. Workaround is this:

# /usr/sbin/envconfig -q

You should see:

ENVMON_HIGH_THRESH =

No value causes the default to be used which is 60. You have to manually set it.

# /usr/sbin/envconfig -c ENVMON_HIGH_THRESH=60
ENVMON_HIGH_THRESH = 60
proceed....
Environmental Monitoring Daemon started.

I did this on my DS10 and haven't see the problem since.

Re: temperature warning messages

Hi,
My script shows that even at the time when warning messages pop out, the actual temperature remains low (around 34~35), so I tend to agree with Victor that this is a known bug to V5.1B-1 on DS10.

I'll play around with ENVMON_HIGH_THRESH and let you know when it's working.

Thanks.
