Power Supply and Fan Status are not visible in CLI

Hi everyone,

 

I want to see the chassis power supply and chassis fan status of a device from CLI, using "tmsh show sys hardware" command. But there is no information about the power supply and fan status. What might be the issue?

 

Thank you.

Best Regards

 

  • Can you check if you are running LB device on VM or vCMP guest?

    Hi Samir,

    It is a hardware appliance and it is not running as vcmp guest.

  • See the below details.

    [root@VIP4400-R15-S35:/S2-green-P:Active] config  tmsh show sys hardware|grep -iA 9 "Chassis Fan Status"

    Hi Samir,

     

    When I enter the command you type, I get nothing. There is no information about the Chasis Fan Status or Power Supply Status.

  • I suspect you maybe on Guest, can you confirm that by running this below command,

    tmsh show sys hardware | grep -A1 Platform

    If it says Guest, you may not able to see power/fan status. Only if its a hardware, you would see.

    Also if it was a hardware, I'm positive you should have atleast seen Down or something else. But since you get blank, I'm suspecting it could be a guest machine.

      Hi,

       

      Thank you for your attention but it is hardware appliance.

  • Hello Canan.

    You could be facing some bug or matching some specific condition.

    https://cdn.f5.com/product/bugtracker/ID720104.html

    https://support.f5.com/csp/article/K18802953

    I recommend you in future questions to provide more information about your environment (like release, platform or command output), this could help us to understand what your issue is.

    Anyway, if I were you I would try to search in your device stats (psu, fan) if this information is represented correctly or not. I don't remember exactly the table name, just search for it with this command:

    tmctl

    An example:

    tmctl -w 300 blade_temperature_status_stat

    Regards,

    Dario.

      Hi Dario,

      Thank you for your reply, I try to search stats with the commands you wrote. But there is no information about the FAN or PSU on the table. As you stated it could be a bug or something.
