I am having similar issues with the ZCM 10.2.1 update. I am running ZCM on SLES 10 SP3 with all recent updates. I attempted to install the ZCM 10.2.1 and the status is "Ready". Under the Deploying System Updates, there is 1 "Successful". When I click the 1 "Successful" or the "Selected Devices Stage" it reports that the update completed. The problem is when I look at the version of the ZCM server it reports only, ZAM, ZPM

I have not applied the PRU and I have tried the zman supr "Update for ZCM (10.2.1)" command to no avail.
