Owner IDs define users to DFSMSrmm. Owners can be individuals, departments, or any logical grouping of people. General users can change information for their own owner ID, once they have been defined to DFSMSrmm.

If a user who is not defined to DFSMSrmm runs a job that writes to a volume managed by DFSMSrmm, DFSMSrmm automatically records information about the user. DFSMSrmm adds an owner record for the user, using the user ID that requested the job as a DFSMSrmm owner ID. If you want DFSMSrmm to automatically notify the owner when a volume he owns is being considered for release, you must manually add the owner's user ID and node, or a valid e-mail address, to this owner record.

When you delete an owner, DFSMSrmm prompts you to optionally provide a new user ID so existing volumes can be transferred to a new owner. These topics describe how to add new owners, change owner information, and delete owners from DFSMSrmm.
