I got "Cannot read schedule info. Please look into the log files." when trying to change the backup location in LMS 2.6 Common Service. I don't see any pertinent log file getting updated in /var/adm/CSCOpx/log/. Is LMS having trouble reading the crontab?
Correct, this error indicates a problem accessing the crontab file for casuser. The backup code will try to run crontab -l as casuser. If that fails, but the crontab file actually exists, then you will see this error.
