How to check temperature in CLI mode.

Hi Admin,

How to check temperature in CLI mode of Superdoms. Any specific commands for this.

Viswanadhan.

[Torsten.]

use "ps" command from MP.

Hi Admin,

I got it from MP console. But I am looking for cli command.

[Torsten.]

not sure if there is any. ty the SMH!

Hello,

As a Unix Ambassador and Senior Unix/Linux
Instructor at HP (with additional roles in
IT Architecture and Support), I wrote the following summary on a similar topics several
months ago.

I hope you get some ideas what you can do
Although not all them might apply to your
case I am mentioning them for the sake of others.

Each HP model has the temperature operating
range described in the config guides and
data sheets.

There are many ways to check and/or create
alarms based on ambient changes like
temperature.

Note that temperatures are measured on
airflow IN to the system rather than airflow
LEAVING the system.

In practice, you do not need to know the
temperature, since the EMS warnings are
triggered when action is needed to prevent
the system shutting down. If you are getting
the notifications, then you need to do
something about cooling. The hardware knows
what are acceptable temperatures (it may
vary between server types), and triggers the
events when limits are reached.

In any case, measuring the temperature
depends on the firmware and hardware.
I enclose herewith some of the possibilities to check the current temperature values:

a) Cstm can do it in some versions.

b) EMS will raise alerts whenever an
exceptional condition is met. That can
be captured by OVO, and many other tools,
including open-source Munin-node and Nagios

http://docs.hp.com/en/diag/ems/dm_core_hw.htm#33

c) SFM has Temperature Sensor Provider.
The Temperature Sensor Provider retrieves
the properties such as sensor number, current temperature reading, and temperature
sensor status.

An example:

# sfmconfig -a -l -t SystemTemp -d NULL

Caption DeviceID Status
HP_SystemTemperatureCollection NULL OK

d) Access via console can provide some
details (how much - it depends on the model and firmware). Here is one from rx2600:

MP:CM> ps
System Power state: On
Temperature : Normal
â ¦

From blade server BL860c:

For System Processor Status see the SS command
For Power Supply and Fan status see the Onboard Administrator.
System Power state : On
System Power usage : 203 Watts
System Power allocation : 255 Watts
Ambient temperature : 24 C
Temperature status : Normal
Over Temperature protection: Enabled

e) Some models, have another option through
console. Here are the results on rx7620:

MP:CM> de
Display status of the selected MP entity (for use by trained personnel only)
B - BPS (Bulk Power Supplies)
U - CLU (Cabinet Utilities: Fans, Intrusion, Clock's etc.)
A - PACI (Partition Console Interface)
G - MP (Management Processor)
P - PM (Power Management)
H - Cell Board Controller (PDHC)
Select device: u

f) If you like System Management Homepage
(SMH), than this works nicely:

Home -> System -> Temperature

Status Sensor Location Temp Threshold
OK Temperature Sensor 216 Ambient Temp 22 38
OK Temperature Sensor 217 Processor 0 Temp 62 103

g) On HP-UX 11.31, the cprop(1M) command
provides a command-line interface to most of
the information available from the System
Management Homepage property pages.

Here is a result from HP Education HP-11.31
server running March 2010 Update:

# cprop -summary -c "Temperature"

h) Another open-source tool can be used -
ipmitool. The source code is available from the Sourceforge site:

http://ipmitool.sourceforge.net/

It is easy to build it from the source code.

If "IPMI over LAN" is enabled in the MP
configurations, you can do the following:

# ipmitool -I lan -H -P "" sdr type Temperature

Ambient Temp | D8h | ok | 23.1| 16 degrees C
Processor 0 Temp | D9h | ok | 3.1 | 53 degrees C
Processor 1 Temp | DAh | ns | 3.2 | Disabled

I can probably come up with more ideas if
need be â º

Finally, take a look at envd(1M). The envd
daemon provides a means for the system to
respond to environmental conditions detected
by hardware. Such responses are typically designed to maintain file system integrity
and prevent data loss.

envd works with two threshold levels for
environmental temperature: critical and
emergency (OVERTEMP_EMERG and OVERTEMP_CRIT). By default, when emergency
threshold is reached, envd issues a shutdown.

In general terms:

OVERTEMP_CRIT = over 30 degrees Celsius

OVERTEMP_EMERG = over 34 degrees Celsius -
the usual response to this is for envd to
complete a graceful shutdown

There is another event at about 40 degrees
Celsius which will cause the platform
monitor to just remove DC power to the
system (non graceful halt), but unless
temperatures go up VERY quickly you should
not reach that one.

You cannot change any of these values - nor
should you even attempt to - HP have
determined the safe operating envelopes for
the systems, changing them would probably
invalidate warranty.

Cheers,

VK2COT
