Resuming Duplication

Restarting a duplication operation which has failed because of media or device errors becomes much easier with V5R4M0. Beginning with this release, each saved item selected for duplication is assigned a resume key. If the duplication operation ends prematurely, the associated resume key is provided by BRMS in diagnostic message BRM4137. You can easily restart the failed duplication operation by re-running the DUPMEDBRM command using the command parameters provided in the Recovery information of the BRM4137 message.

The following illustrates how easy it is to restart duplication operations after the media or device error is corrected.

Suppose you run the following command to duplicate VOL001 to VOL002:

DUPMEDBRM VOL(VOL001) FROMDEV(TAPMLB01) TODEV(TAPMLB01) 
MEDPCY(FMT3570E) FROMVOL(VOL001) TOVOL(VOL002)

The command fails after duplicating some file sequences with the following messages in the job log:

Media duplication restart recovery.
   :
(Media or device diagnostic messages)
   :
Media duplication completed with errors.

You correct the device or media error which caused the duplication to fail.
You prompt for the extended help on the Media duplication restart recovery message and retrieve the restart command parameters from the Recovery information.
```
VOL(*RESUME) RSMKEY(669190)
```
You re-run the DUPMEDBRM command using the restart parameters.
```
DUPMEDBRM VOL(*RESUME) RSMKEY(669190)
```

You can use the Work with Media Information (WRKMEDIBRM) command and the Duplication view of the Work with Media Information display to view the saved items remaining to be duplicated. To do so:

Run the WRKMEDIBRM command specifying the volume to be duplicated.
```
WRKMEDIBRM VOL(VOL001)
```

Press F11 twice to get to the Duplication view of the Work with Media Information display.

                                                                         Bottom

From the displayed example, you can see there are three saved items with a duplication resume key. These are the saved items remaining on the volume which have not been duplicated. Restarting duplication using resume key 669190 will complete the duplication operation for these three saved items.
