▼ Generating the virtual library
Using this procedure, you define the remaining characteristics of your virtual library
and media. You supply a barcode range, slot count, and import/export slot count for
the library and define the capacity of the media.
Setting the barcode range defines the set of barcodes that the virtual library will
support. Each batch of cartridges that you subsequently create must be a subset of
the range you define now—you cannot change it later. So Sun recommends setting
this value to the widest range possible, 000000-ZZZZZZ. The virtual library can
then support any barcoding scheme that you will ever need.
By default, the slot count for a virtual library is the maximum defined for the Sun
L700 physical library that the Sun VTL virtual library emulates, 678. Sun
recommends adjusting this value to the maximum possible—4096—so that you are
not needlessly constrained by it later. Once a library is defined, you cannot change
the number of slots that it contains.
Proceed as follows.
1. When the Enter Virtual Library Information dialog appears, enter a
Barcode Starts value in the text field provided ( A below).
The starting value shown, 000000, allows you the greatest range possible. But
whatever you choose, enter exactly six (6) barcode characters when emulating Sun
StorageTek libraries—neither more nor less.
2. Enter a Barcode Ends value in the text field provided ( B above).
The ending value shown, ZZZZZZ, allows you the greatest range possible. But
whatever you choose, enter exactly six (6) barcode characters when emulating Sun
StorageTek libraries—neither more nor less.
