This message may be returned from the VALIDATE POLICYSET or ACTIVATE POLICYSET command. During policy set validation processing, the server has found an archive copy group named group name for management class class name in the currently active policy set, but the copy group is not defined for the management class in the policy set being validated or activated (set name). If policy set set name is activated, attempting to archive files specifiying this management class will fail. Existing archives bound to this management class on the TSM server will be expired based on the defmgmtclass values, or the archive retention grace period for the policy domain, if the default management class does not contain an archive copygroup.
