The RMD or DELE command was issued to delete PDS directory, but when the FTP server attempted to delete the data set, the delete did not complete successfully. Possible causes for this error include the data set is currently in use by someone else, the data set has an unexpired retention period, the data set is located on a tape volume, or the direct access volume containing the data set is not writable.
The RMD or DELE command is rejected. Control returns to the client for further command processing.
Reissue the command. If the problem persists, contact the system programmer for the server system.
