Error: 'Please make sure the Health Monitor is started' When Trying to Run a Health Check on an HPE Proliant Server

Overview

There may be times when you try to run a health check (e.g., fans or power supply status) on an HPE Proliant Server with the command hpasmcli and get the error below:

ERROR: Could not open /dev/cpqhealth/cdt.
Please make sure the Health Monitor is started.

This article provides solutions to resolve the error described above.

 

Solution

You may try updating the HP hardware monitoring tools or resetting the health services to resolve the issue. If they do not solve the error, submit a request to support (see below for more details).

 

Update HP Hardware Monitoring Tools

Please check the hp-health version with the following command:

rpm -q hp-health hpasm hprsm

If it is an old version, you might need to update it.

 

Reset the Health Services

Please stop and restart the health services and check if the file /dev/cpqhealth/cdt exists.

service hp-health status
service hp-health restart

 

File a Support Ticket
If the previous solutions did not work, please file a support request in the Skyvera Support Portal and provide the following data:

  • Server Model (find the model string with dmidecode | grep -i proliant)

  • Name and version of your Linux distribution

  • The output of the following commands:

    ls -l /dev/cpqhealth
