Novell ZENworks 7 Desktop Management Support Pack 1 - ZDM7 SP1
When installing HP 2 or HP 3 for ZENworks 7sp1 IR3a to a cluster, the cluster resource object is unable to be selected, so it will not install the hot patch. It is still able to be installed to a node.
Fixed in ZENworks 7 Desktop Management Service Pack 1 Interim Release 4, see KB 3484245 "Updates to Novell ZENworks 7 Desktop Management" which can be found at https://www.novell.com/support
Workaround: The problem is with the zcommon.jar and smanager.jar files. You can revert to the IR 3a versions of these files in order to fix the problem.
