Volser Ranges for Media Types
Note: You can view and modify volser ranges from the Specialist (see “Specialist
Features and Functions” on page 396).
The Volser Ranges window (Figure 142 on page 238) allows you to enter up to 50
or 256 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 3494
Tape Library. It is also used to assign stacked physical volumes to storage pools
when they are inserted. When a range is added or modified, the system combines
overlapping ranges with the same media type automatically and checks for range
conflicts.
When a volser range changes, the media types and storage pools for existing
volumes in the 3494 Tape Library do not change. Volumes inserted subsequently
reflect the new set of ranges and associated media types and storage pools. A
volser range cannot conflict with existing volsers of a different media type.
A volume’s media type is determined by using the following rules:
v The media type that the vision system returns is used as a first choice.
v
If the media type returned is for a J - or K -type cartridge and there is more than
one logical library in the physical library, the volser ranges are used to
determine the logical library to which the volume is assigned.
v
If the vision system cannot determine a volume’s media type, the volser ranges
are used. If the volume being inserted is within one of the ranges, the range’s
associated media type is used. The search of the ranges is an inclusive search.
v If the volser does not fall into one of the ranges, the system uses the default
media type defined during the Teach process to determine the media type.
v
If there is no default media type, the volume is ejected, and an operator
intervention is set.
To add a range, enter the two volsers in the From and To fields, select a media
type, select a home pool (if it is a stacked volume range) then select the Add /
Modify push button.
To expand a range, double-click the range, expand the volsers, select the media
type, select the home pool (if it is a stacked volume range), then select the Add /
Modify push button.
To delete a range, double-click the range, then select the Delete push button.
To determine if a volser is in a range, enter the volser in the From entry field, then
select the Volser in range? push button.
To query the number of volsers in a range, highlight the range in the list box, then
select the Total volsers in range push button.
The Volser Ranges window has the following controls:
From and To entry fields
The volser entry fields must contain six characters. The characters can be
letters, numerals, or a space. The two volsers must be entered in the same
format. Corresponding characters in each volser must both be either
alphabetic or both be numeric. For example, AAA998 and AAB004 are of
the same form, but AA9998 and AAB004 are not.
