Configuring and Operating the DLT4700 Mini-Library
DLT4000/DLT4500/DLT4700 Cartridge Tape Subsystem 5-9
5.5 Selecting Density
Section 5.5 describes the loader's density select feature.
Ways of Selecting Density
The user can select density by using any of the following:
1.
On all read operations and all write append operations, the recorded density is the
density to be used.
2.
On a Write from BOT, the tape density may be changed by:
•
The Density Select button. Using the Density Select button always
overrides a host selection.
•
A programmable host selection via your operating system. (The Density
Override indicator is off, indicating automatic or host density selection.)
•
Native default density 20.0 GB and 40.0 GB Compress (assuming the
use of a DLTtape IV and the Density Select button or the host selection
was not used.)
____________________ CAUTION _________________________
Doing any Write from BOT destroys data on tape.

How to Select Density
To select density with the DLT4700 mini-library:
1.
Press the Load/Unload button to load the cartridge into the drive. The yellow
Tape in Use indicator blinks while the tape loads and calibrates.
2.
After calibration completes, the yellow Tape in Use indicator remains lit.
3.
The indicator showing the tape's prerecorded density indicators, such as 2.6 or
6.0.
4.
The user can use the loader operator control panel at various times, not just after
loading a tape. Density selection is inactive until the write from BOT command is
issued. The controller remembers the density selection state until you do one of
the following:
•
Change the density selection
•
Eject the magazine from the loader
