Volser Range for Media Types

This panel allows the entry of up to 50 volser ranges and associated media types. The volser ranges are used to help determine a physical volume's media type when it is inserted into the library. When a range is added or modi®ed, the system automatically combines overlapping ranges with the same media type and checks for range con¯icts.

When a volser range changes, the media types for existing volumes in the library do not change. Volumes inserted subsequently will re¯ect the new set of ranges and associated media types. A volser range cannot con¯ict with existing volsers of a different media type.

A volume's media type is determined by using the following rules:

1.The media type returned by the vision system is used as a ®rst choice.

2.If the media type returned is for an HPCT type cartridge and there is more than one logical library in the physical library, the volser ranges are used to determine to which logical library the volume is assigned.

3.The volser ranges are used to determine a volume's media type if it cannot be determined by the vision system. If the volume being inserted appears within one of the ranges, the range's associated media type is used. The search of the ranges is an inclusive search.

4.The system uses the default media type de®ned during the teach process to determine the media type if the volser does not fall into one of the ranges.

5.The volume is ejected if there is no default media type.

To add a range, enter the two volsers, select a media type and select the

Add/Modify range button.

To modify a range, double-click the mouse on the range, modify the volsers, select the media type, and select the Add/Modify range button.

To delete a range, double-click the mouse on the range, and select the Delete range button.

To determine if a volser is in a range, enter the volser in the ªFromº entry ®eld and select the Volser in range? button.
