  • Hi,

    I am not sure what you have done but root cannot run crontab.
    I would add it into /var/adm/cron/cron.allow

    echo "root" >> /var/adm/cron/cron.allow

    But I am not sure if this work even for root user.

    Check also /var/adm/cron/cron.denny

  • Thanks for your response pavel.
    I checked the files, In var/adm/cron/cron.allow lpar2rrd is there and
    in var/adm/cron/cron.deny it is empty.
    What I have to do further? 
  • try to add root in allow file and remove denny file

  • ok added root in allow file. deny file is already empty.
    I should remove lpar2rrd in allow file and include root? or both can be in that file ?
  • leave both.

    It is an operating system issue (not related to lpar2rrd), it is hard to support you without having access to system logs etc.
    Your Linux admin should be able to resolve that ...
  • ok thank you pavel
