Challenge
After installing Veeam 9.5 Update 3a and simultaneous upgrade of vSphere from 6.5 to 6.7 Veeam vSphere Web Client Plugin might stop working for vSphere HTML5 Web Client. However it is still operational in vSphere Flash/Flex Web Client.
The issue is only reproducible in case the plugin was present on the vCenter prior to upgrade. The installation logs on vSphere side will show:
[<date and time>] [INFO ] vc-extensionmanager-pool-<id> 70000019 100003 200001 com.vmware.vise.extensionfw.ExtensionManager Plugin package com.veeam.backupui.VeeamBackupUi:9.5.0.1922 was not deployed because attribute type="html" is missing, which is normal if this is a Flex plugin
Cause
Solution
Issue resolution requires complete plugin re-installation:
- Unregister the plugin via Enterprise Manager interface.
- Connect to the vCenter appliance via SSH and Remove the plugin:
rm -r /etc/vmware/vsphere-client/vc-packages/vsphere-client-serenity/com.veeam.backupui.VeeamBackupUi-*/
rm -r /etc/vmware/vsphere-ui/vc-packages/vsphere-client-serenity/com.veeam.backupui.VeeamBackupUi-*/
rm /etc/vmware/vsphere-client/cmCatalog/com.vmware.cis.com.veeam.backup.quickbackup.zip
rm /etc/vmware/vsphere-ui/cmCatalog/com.vmware.cis.com.veeam.backup.quickbackup.zip
rm /etc/vmware/vsphere-client/cmCatalog/com.vmware.cis.com.veeam.backup.veeamzip.zip
rm /etc/vmware/vsphere-ui/cmCatalog/com.vmware.cis.com.veeam.backup.veeamzip.zip - Restart VMware services responsible for web-interface:
- Either via SSH to the vCenter:
service-control --stop vsphere-client service-control --stop vsphere-ui service-control --start vsphere-client service-control --start vsphere-ui
- Or via Appliance Manager (port 5480) by restarting these services:
VMware vSphere Web Client VMware vSphere Client
- Either via SSH to the vCenter:
- Install Veeam vSphere Web Client Plugin from Enterprise Manager.
- Login to vSphere Web Client HTML5.
- Please note the last step should be performed twice – on first login plugin will be installed, however, it will only appear after the second login.
