Specify (E,E) for the DYNVOL Control-M/Tape parameter. This value causes volume records for external volumes that are checked in to be automatically added to the Media Database. It also instructs Control-M/Tape to mark the volume being checked in as External (in the volume record in the Media Database).
Specify Y for the DYNDS Control-M/Tape parameter to automatically add the data set records to the Media Database for the data sets listed in the External Volume Check-In screen.
Note: Specifying Y for the DYNDS and DYNVOL Control-M/Tape installation parameters causes volumes and data sets to be automatically defined any time an accessed volume or data set is not described in the Media Database. Therefore, these parameters do not only affect external volumes.
