Library Components

Storage Cells

The DLT Library contains storage cells for 30 DLT type IV or type IIIXT cartridge
tapes. Figure 1–3 shows the cell locations. If Auto Clean is enabled, column 0,
cell 7 cannot be used for a data cartridge, because a cleaning cartridge must be
placed in that cell. Auto Clean is discussed in Chapter 3 of this guide.
Figure 1–3. Storage Cell Locations
In this figure, the number in parentheses equals the total cartridge count. The other
number is the storage cell number in one of the three columns. The storage cell
layout as a whole is called the "array." The array targets are used for robotic
calibration during initialization.

Tape Drives

The DLT Library can contain up to three tape drives (DLT4000 or DLT7000,
differential). The library numbers the drives from 0 through 2, starting from the
bottom. Some host software might number the drives from 1 to 3.
If a mechanical failure occurs, or if desired for other reasons, cartridge tapes can be
mounted into the tape drives manually. Refer to Chapter 3 for more detailed
information.
