All fail when 1 doesn't aplpy
I had a full deployment failure because "You have requested to create an update configuration on a machine that is not registered for Update Management." The one mentioned in the error was connected to update management and showed in the OMS logs. I'll contact support, BUT....
It would make more sense if the deployment would work for everything that it can and just fail on those 1 or 2 that it cannot apply on. None of the deployment happened because of this 1 failure.
From our perspective, its expected behavior to have the update job’s status to be failure if there is an issue with 1 or more machines being patched.
It is our endeavor to ensure, any issues are bubbled up and shown. Hence we mark the job status as failure and not leave any thing to ambiguity by showing any other mixed state or wrongly indicate success.
