A communications problem with the service processor occurred. No Capacity on Demand changes can be made, but you can continue to run with the current Capacity on Demand resources. Look for errors with SRCs of the form B1xxxxxx or B7xx69xx in the Serviceable Event View. Work those errors first. If that does not correct the problem, re-IPL the system. If that does not correct the problem, contact your next level of support.
