Novell ZENworks 10 Configuration Management with Support Pack 2 - 10.2 Patch Management
Applying a patch to a device group selects all devices in the group, and includes devices that don't require the patch.
The devices must be deselected per the ZCC instruction: "Please deselect any devices that should not be patched ".
This is fixed in version 10.2.2 - see KB 7004803 "ZENworks 10 Configuration Management 10.2.2 - update information and list of fixes" which can be found at https://www.novell.com/support
Prior to 10.2, the devices that did not require a patch were not selected by the deployment wizard, which made the selection process easier.
