Issue/Introduction

When placing the cluster in retreat mode, the following error is seen:



Environment

VMware vCenter Server 8.0
VMware vCenter Server 7.0.0

Cause

  • This error can occur while putting the cluster in retreat mode because there may be entry present in the advanced settings for the same cluster ID.
  • The entry could have invalid syntax for the same cluster and thus it may not allow the addition of a new entry for same cluster ID.


For example : 

Wrong Syntax:  config.vclscluster.domain-c(8).enabled

Correct Syntax: config.vcls.clusters.domain-c8.enabled

Resolution

  • The entry of the name column in advance settings cannot be modified, and vCenter cannot add the new entry as well, if the entry of the same cluster ID is already present.
  • The wrong entry added in the advanced settings of the same cluster must be removed, which is not possible from advance settings of the VC UI.


Note: Please take the snapshot of the VC VM and create a proper backup of the vpxd.cfg file.

  • use the VI editor find the line which has entry of advance settings of the vCLS VMs for the required cluster.

  <vcls>
    <clusters>
      <domain-c(8)>
        <enabled>True</enabled>
      </domain-c(8)>
    </clusters>
  </vclsclusters>

  • Delete the entire entry starting at <vcls> and ending at </vcls>.
  • Restart the VPXD service:  #service-control --restart vmware-vpxd
  • vCLS VMs should now automatically be deployed in the given cluster.

Additional Information

Impact/Risks:
Cannot add new Entry for same cluster ID again in advance settings for creating vCLs VMs
