Examples

Mount a tape volume containing a data set name, PRODUCT.LISTING, that is duplicated in two volumes, ABC001 and ABC002. Of the two volumes, you know that ABC002 has the most recent creation date. You have used the LATEST parameter on the DUPDSN record:
```
vmtape mount * dsn product listing (nowait
MOUNT ‘181' REQUEST ACCEPTED.
```

To be sure the correct tape was mounted, query the mount request:

vmtape query requests
HARRY 181 ABC002 MOUNTING DEV=680 18track 38K

In this case, you have omitted the DUPDSN Record from the configuration file, or specified the ERROR parameter:
```
vmtape mount * dsn product listing
MORE THAN ONE TAPE WITH DSN ‘PRODUCT.LISTING'.
```
