Dell VxRail: VSAN Tab is missing in the HTML5 Client

Issue: VSAN Tab is missing in the HTML5 Client post upgrade to 4.7.x version (VCSA 6.7)

Directory "com.vmware.vsphere.client.h5vsan-6.7.0.20000" might be missing in the vsphere-client-serenity directory.

To resolve this issue, follow the workaround below:

1. SSH to the affected vCenter
2. Change to directory: /etc/vmware/vsphere-ui/vc-packages/vsphere-client-serenity
3. Confirm that the directory "com.vmware.vsphere.client.h5vsan-6.7.0.20000" is missing.
4. Create a new directory called "com.vmware.vsphere.client.h5vsan-6.7.0.20000"
5. SSH to the working vCenter
6. Confirm that the directory "/etc/vmware/vsphere-ui/vc-packages/vsphere-client-serenity/com.vmware.vsphere.client.h5vsan-6.7.0.20000" is present on the appliance.
7. Use WinSCP to connect to the working vCenter and copy the contents of "com.vmware.vsphere.client.h5vsan-6.7.0.20000" to the local machine.
8. Copy the files from the local machine to the newly created directory on the affected vCenter.
9. Run the following command on the affected vCenter to change the ownership of all files and subdirectories to "vsphere-ui users" - find /etc/vmware/vsphere-ui/vc-packages/vsphere-client-serenity/com.vmware.vsphere.client.h5vsan-6.7.0.20000

   xargs chown vsphere-ui:users

10. Should VCHA be enabled, put this into Maintenance Mode to prevent a failover.
11. Reboot the affected vCenter virtual machine and wait for the plugins to load.
12. Confirm that the VSAN plug-in tab is present in the vSphere Client.
