Environment

VMware vCenter Server 6.5.x

Cause

The deployment method of DirectApiBundleDeployer causes caching issue with rpm installation which may make plugins deployment failed when vsphere-ui service started. In this sample, the client can not start in 15 minutes, but normally it should take no more than 5 minutes that was caused by failure of plugin deployment.

Resolution

This issue is resolved in vCenter Server 6.7.

Workaround

  1. Ensure the vsphere-ui service is in stopped status by running this command:
service-control --status --all
  1. Delete or rename the HTML5 client work folder.
    • VCSA: /usr/lib/vmware-vsphere-ui/server/work
    • Windows VC: C:\ProgramData\VMware\vCenterServer\runtime\vsphere-ui\server\work
Note: Ensure backup of the folder is available
  1. Start the vsphere-ui service by running this command:
service-control --start vsphere-ui
 
If the issue persist, perform the below steps:
  1. Ensure that the vsphere-ui service stopped.
  2. Delete the HTML5 client work folder.
  3. Open webclient.properties file that is located:
    • VCSA: /etc/vmware/vsphere-ui
    • Windows VC:\ProgramData\VMware\vCenterServer\cfg\vsphere-ui
  4. Add (or edit) the following property
pickup.deployer=true
  1. Start the vsphere-ui service:

    service-control --start vsphere-ui
