Virtual Storage Console: User Interface extensions are not pulled by vCenter

Last Updated:

Applies to

  • Virtual Storage Console
  • vCenter


This article describes a specific scenario where the Virtual Storage Console plugin is not visible in the vSphere WebClient.

In this scenario, vCenter is unable to pull the VSC UI extensions after registration.

The normal process is as follows:

  1. VSC is registered to vCenter (via https://<vsc_server>:8143/Register.html)
  2. VSC advertises to vCenter that there are new UI extensions to pull
  3. vCenter will successfully add new extensions to inventory (com.netapp.nvpf & com.netapp.nvpf.webclient). This is confirmed in vCenter's MOB (Managed Object Browser). 
  4. vCenter will reach out to the VSC server and pull across a "webclient_deployment_bundle".  UI extensions from this bundle are copied to directories on the vCenter server.
In some rare cases, step 4 will fail. This can be confirmed by the following:
  1. "com.nvpf" UI folders are not present on the vCenter server
This can be confirmed by verifying that "com.nvpf" folders are not present at the following locations:
Note: The path depends on the vCenter version.
  • On VCSA, the UI folders are located at:

  • /etc/vmware/vsphere-client/vc-packages/vsphere-client-serenity

  • /var/lib/vmware/vsphere-client/vc-packages/vsphere-client-serenity/

  • On a Windows vCenter server, the UI extensions can be found at:

  • %PROGRAMDATA%/VMware/vSphere%20Web%20Client/vc-packages/vsphere-client-serenity/
  • %PROGRAMDATA%/VMware/vCenterServer/cfg/vmware-vpx/extensions

  1. vSphere "vsphere_client_virgo.log" log has the following events:
