Overview of the issue: vCenter Update Manager Tab Missing

VMware vCenter Update Manager is a tool used to automate and manage the process of updating and patching VMware vSphere environments, including ESXi hosts and virtual appliances.

When using HTML for vCenter administration, you may find the Update Manager tab missing in a Windows-based vCenter. This behavior is anticipated in HTML client, as stated in version 6.7 release notes. It's important to note that utilizing Update Manager in the vSphere Client (HTML5-based GUI) is exclusively supported for Update Manager running within the vCenter Server Appliance.

You may have this issue in these common scenarios:

  • vCenter Update Manager (VUM) may not be properly configured.
  • the VUM plugin within the vCenter Server might get disabled or unregistered.
  • VUM versions are not compatible with your updated vCenter Server version. If you've recently upgraded your vCenter Server, you may need to upgrade or reinstall VUM to match the new version.
  • Network-related issues, including firewall rules blocking communication between vCenter Server and VUM

Resolution of vCenter Update Manager Missing

To resolve VMware update manager not showing up, you could follow up:

1. Fix any Trust Anchor mismatch in Service registrations to Lookupservice following the procedure documented in vCenter Server or Platform Services Controller certificate validation error messages for external solutions in environments with an External Platform Services Controller.

2. Restart the vSphere Web Client and the vSphere Client services

service-control --restart vsphere-ui
service-control --restart vsphere-client

3. If the Update Manager Plug-in is still missing after fixing Trust Anchor mismatch in both clients, manually place the Plug-in files to their expected location:

▶ Take an SSH session to vCenter Server Appliance

▶ Download Update Manager Plug-in files from these locations:

  • https://:9087/vci/downloads/
  • https://:9087/vci/downloads/

▶ Place the downloaded files to below folders respectively

  • /etc/vmware/vsphere-ui/cm-service-packages/com.vmware.cis.vsphereclient.plugin/.
  • /etc/vmware/vsphere-client/cm-service-packages/com.vmware.cis.vsphereclient.plugin/

▶ Check the version of Update Manager service registration in VMware Lookup Service using the following command:

  • python /usr/lib/vmidentity/tools/scripts/ list --url http://localhost:7080/lookupservice/sdk --type client --product com.vmware.vum

▶ Extract the Update Manager Plug-in zip files downloaded in Step 2 and place them in their expected location. The target directories must contain the plug-in versions registered in VMware Update Manager:

  • to com.vmware.cis.vsphereclient.plugin-
  • to com.vmware.vcIntegrity.vcIntegrity-

▶ Change the owners of the plug-in directories.

  • vsphere-ui for /etc/vmware/vsphere-ui/cm-service-packages/com.vmware.cis.vsphereclient.plugin/com.vmware.vum.client-
  • vsphere-client for /etc/vmware/vsphere-client/cm-service-packages/com.vmware.cis.vsphereclient.plugin/com.vmware.vcIntegrity.vcIntegrity-

▶ vsphere-client for /etc/vmware/vsphere-client/cm-service-packages/com.vmware.cis.vsphereclient.plugin/com.vmware.vcIntegrity.vcIntegrity-

▶ Restart vSphere Client and vSphere Web Client:

service-control --restart vsphere-ui
service-control --restart vsphere-client

Resolving the issue of vCenter 6.7 upgrade to 7.0 Update Manager not showing up will assist you in addressing similar problems with your vCenters after an upgrade.
