Power Supply and Fan Status are not visible in CLI

[Canan]

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.

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.

Interesting... Plz ease Open Support case.

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.

[jaikumar_f5]

Can you open a support case and keep us posted too.

Hello Canan.

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

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.
