Description

This KB article explains how to fix the following chassisd error message: "error: the chassis-control subsystem is not running".

Symptoms

1. When any chassisd-related show command is issued, the following error message is observed in the output:

Example:

user@hostname>show version
error: the chassis-control subsystem is not running       <<<<<<<<<<<<<<

user@hostname> show chassis hardware
error: the chassis-control subsystem is not running       <<<<<<<<<<<<<<

2. CPU utilization of the chassisd process and others may look normal.

3. No system alarms nor core-dumps generated.

 

Solution

The said error message is observed when the chassisd is unable to process any requests due to the I2C bus getting stuck and thereby the chassisd daemon becoming unresponsive. During this state, the chassisd process is not running and stuck in a problematic state.

And like said in the Symptoms, when any chassisd-related show command is issued, the output returns with the following message: "error: the chassis-control subsystem is not running".

The solution is to restart the chassisd process by issuing the following command:

user@hostname> restart chassis-control

[Note that when the chassisd process is restarted, the device may automatically reboot.]

>>In case restarting the process doesn't work please reboot the device, and contact JTAC for further technical assistance.
