When trying to sync updates in vCenter LifeCycle Manager, it may fail and throw the following error:
Error: ‘integrity.fault.HostPatchInvalidVendorCode’
It is usually followed by a variety of error messages, such as: invalid vendor code XXX in patch metadata.
If there are no customizations in your vCenter, you can easily fix this by resetting the vLCM update database, as per KB2147284. Run the following commands from a shell in vCenter:
service-control --stop vmware-updatemgr /usr/lib/vmware-updatemgr/bin/updatemgr-utility.py reset-db rm -rf /storage/updatemgr/patch-store/* service-control --start vmware-updatemgr
