Table: Reasons for the NetBackup plug-in not appearing in the vSphere Web Client

Reason

Description and recommended action

The NetBackup plug-in does not support the vCenter version.

Messages similar to the following may appear in the vsphere_client_virgo .log file:

javax.net.ssl.SSLHandshakeException: Received fatal alert: 
handshake_failure

For a list of supported vCenter versions for the plug-in for vSphere Web Client, see the following document:

Support for NetBackup 7.x and 8.x in virtual environments:

http://www.veritas.com/docs/000006177

You have not used the default URL for the plug-in ZIP-file download (securely hosted by the NetBackup master server).
Instead, your plug-in download URL uses the HTTP protocol (http://) rather than the secure HTTPS protocol (https://).

In this case, the default vCenter configuration does not allow the plug-in to be downloaded and deployed. Messages similar to the following may appear in the VMware vsphere_client_virgo.log file:

The plugin package download was blocked because the URL 
is not secure. To allow http URLs add allowHttp=true to 
webclient.properties

See the procedure To allow installation of the plug-in over an HTTP URL.

A previous instance of the NetBackup plug-in did not properly clean up after uninstallation.

Do the following:

On the vCenter server, stop the vSphere Web Client service:
To use the command line, the name of the service is vsphere-client.
To use the vSphere Web Client interface, the name of the service is VMware vSphere Web Client.
For assistance with the command line or vSphere Web Client, see the VMware article "How to stop, start, or restart vCenter Server 6.x services (2109881)":
https://kb.vmware.com/kb/2109881

Remove references to the plug-in, as follows:

On a vCenter appliance, remove the directories or files that the following find command returns:

# find / -iname "*netbackup*"

On a Windows vCenter, remove the directories or files that the following dir commands return:

dir "%programdata%\*netbackup*" /s /a /b

dir "%programfiles%\*netbackup*" /s /a /b

Note:

For a VMware Platform Services Controller (PSC) environment with multiple vCenters, you need only uninstall the plug-in on the vCenter where the plug-in was installed. However, you should remove references to the plug-in from all of the vCenters that are managed by the PSC.

On the vCenter server, start the vSphere Web Client service.

To allow installation of the plug-in over an HTTP URL

Add the following directive to the vCenter's webclient.properties file:
allowHttp=true
The webclient.properties file may be located in the following directory:
Windows: C:\ProgramData\VMware\vSphere Web Client\
Linux:
- In vCenter 5.5.x: /var/lib/vmware/vsphere-client/
- In vCenter 6.0 and 6.5: /etc/vmware/vsphere-client/
Restart the vSphere Web Client service.
The following VMware articles contain further information on starting the vSphere Web Client service:
vCenter 5.x: https://kb.vmware.com/kb/2054085
vCenter 6.0 and 6.5: https://kb.vmware.com/kb/2109887
Log on again to the vSphere Web Client.
When you log on, the plug-in is then installed.
