Additional EDGBKUP return code information

If DFSMSrmm encounters an error during restore processing, DFSMSrmm completes the restore and sets a return code of 8 under these conditions:

DFSMSrmm finds that the previous update of the control data set failed and the error was not corrected.
DFSMSrmm cannot match the control data set and the journal. Journal copies used as input to forward recovery are out of sequence with other journal copies.
DFSMSrmm can match the journal and the control data set, but the last set of journal records is incomplete. DFSMSrmm issues a message to indicate that forward recovery is completed to the point of the last complete set of journal records.
DFSMSrmm detects discrepancies in the journal records used to perform a forward recovery.

For either a return code of 8 or 12, you should decide whether the restored control data set is acceptable, then take corrective actions. You can try to recover again by using the correct control data set and journal data sets. If you do not have any other backups or journals from which to restore, you will have to accept the restored control data set.

DFSMSrmm sets values in the control data set control record to indicate that the recovery did not complete satisfactorily. Until these values are reset, DFSMSrmm always prompts the operator at DFSMSrmm startup time to determine if the control data set can be used or not. To clear the values, run EDGUTIL VERIFY(ALL) to validate the recovered control data set. If processing completes successfully, DFSMSrmm resets the control data set control record and accepts the control data set for use without prompting the operator at future startup times.

If EDGUTIL finds errors in the restored control data set, correct the errors and run EDGUTIL again. Start DFSMSrmm and use the restored control data set while you issue RMM TSO subcommands. Correct the errors in the control data set by using RMM TSO subcommands or the EDGUTIL utility with the MEND parameter as described in Mending the control data set to update the information in the control data set.
