RDFCOM Messages
Effect. START RDF processing is aborted.
Recovery. Refer to the Operator Messages Manual for a description of the error code.
For additional details about understanding and correcting file-system errors, see the
Guardian Procedure Errors and Messages Manual. If possible, correct the error and
reenter the command that encountered the error. Otherwise, see your system
manager.
error#
is the file-system error number that identifies the specific error.
Cause. The configuration file data cannot be created or cleared while START RDF
processing is performed after INITIALIZE RDF.
Effect. START RDF processing is aborted.
Recovery. Refer to the Operator Messages Manual for a description of the error code.
