Environment

VMware vCenter Server Appliance 8.x

Cause

The VCLS VMs were either deleted or previously misconfigured, followed by a vCenter reboot. As a result of this action, the vpxd.cfg file was left with incorrect data, preventing the vpxd service from starting.

Resolution

    1. Connect to the VCSA via an SSH session as the root user.
    2. Create a backup of the file /etc/vmware-vpx/vpxd.cfg.
    3. Verify that the vmware-vpxd service is not running, or stop it using the command:
      service-control --stop vpxd.
    4. Remove the VCLS entries from the /etc/vmware-vpx/vpxd.cfg file.

    Workaround 1: Run the following command to remove the VCLS entries automatically:
    sed '/<vcls>/,/<\/vcls>/d' -i /etc/vmware-vpx/vpxd.cfg.

    Workaround 2: Manually edit the vpxd.cfg file using the vi editor:

    • Run vi /etc/vmware-vpx/vpxd.cfg.
    • Remove the section related to VCLS, which looks similar to:
    <vcls>
<clusters>
<domain-c22>
<enabled>False</enabled>
</domain-c22>
<domain-c22:f696e05a-6cf8-4d02-af1c-10e81f90ec81>
<enabled>False</enabled>
</domain-c22:f696e05a-6cf8-4d02-af1c-10e81f90ec81>
<domain-c86>
<enabled>false</enabled>
</domain-c86>
<f696e05a-6cf8-4d02-af1c-10e81f90ec81>
<enabled>False</enabled>
</f696e05a-6cf8-4d02-af1c-10e81f90ec81>
</clusters>
</vcls>
     
    • Press the Esc key, type :wq!, and press Enter to save and exit the file.

    1. restart vpxd service using:
      service-control --start vpxd.

    2. post which verify restarting all services:
      service-control --stop --all && service-control --start --all.

    3. Re-run the update after completing these steps.

cd /etc/vmware-vpx

less vpxd.cfg

Copy the details and paste in the notepad++ and then confirm the line that patchrunner.log is throwing an error for and then follow the resolution.

Then you can follow the workaround1 or 2 once the lines are verified as mentioned above and in the resolution section.
