Backup Server activates non-rewinding logic only if the label version on the tape is greater than or equal to 5. Therefore, a dump command with the with init clause is needed to activate this logic. If a dump without init is initiated onto a volume with a label version less than 5, you are prompted to change the volume, and the dump starts on the next volume. The label version of a multi-volume dump does not change in the middle of the volume set.
Table 12-9 defines the label versions for which the new behavior is enabled.
