Code Capture wasn't able to reveal anything unfortunately.
However, digging a bit deeper I located the four Download Sources specified in the /usr/lib/vmware-updatemgr/bin/vci-integrity.xml file:
<ESX4xUpdateUrl id="integrity.SoftwareUpdateURL.ESX4x.addon.description">https://hostupdate.vmware.com/software/VUM/PRODUCTION/addon-main/vmw-depot-index.xml</ESX4xUpdateUrl>
<ESX4xUpdateUrl id="integrity.SoftwareUpdateURL.ESX4x.description">https://hostupdate.vmware.com/software/VUM/PRODUCTION/main/vmw-depot-index.xml</ESX4xUpdateUrl>
<ESX4xUpdateUrl id="integrity.SoftwareUpdateURL.ESX4x.iovp.description">https://hostupdate.vmware.com/software/VUM/PRODUCTION/iovp-main/vmw-depot-index.xml</ESX4xUpdateUrl>
<ESX4xUpdateUrl id="integrity.SoftwareUpdateURL.ESX4x.vmtools.description">https://hostupdate.vmware.com/software/VUM/PRODUCTION/vmtools-main/vmw-depot-index.xml</ESX4xUpdateUrl>
But there wasn't any flags/settings to be found for source enabled/disabled in this file...
Further on, when either disabling/enabling the sources in the GUI I've found this trace of events in the /var/log/vmware/vmware-updatemgr/vum-server/vmware-vum-server-1.log:
2024-02-01T09:11:50.305Z info vmware-vum-server[12377] [Originator@6876 sub=Activation] [activationValidator 366] Leave Validate. Succeeded for integrity.option.OptionManager.setURLEnabledByName on target: Integrity.OptionManager
Would that indicate a possibility to change this with a script command somehow?
