18 Tape Library Components Chapter 1
Storage Cells
The library contains storage cells for 228 to 690 cartridges, excluding the CAP
cells. The number of cells is determined by how many drives are installed and
whether the tape library has the standard rear window panel or the expansion
frame. The expansion frame provides additional storage cells for 294
cartridges.
Cell Locations
Cartridges are stored in cell arrays that hold six cartridges. Cell arrays are
stacked in columns and these columns are arranged in a circle around the
robot assembly. Columns can hold up to 42 cartridges.
Table 1 on page 20 lists tape library storage capacities. Figure 3 on page 21
through Figure 4 on page 22 show cell locations for the 20/700 tape library
in its various configurations.
Note The following statements apply to cell locations:
1. The library uses array targets for robotic calibration during an Initial
Program Load (IPL).
2. Never put data cartridges in the reserved cells (refer to Figure 3 on page
21 for more information). If you do not want to store diagnostic and/or
cleaning tapes in these cells, you must leave them empty.
3. The library does not use the drive and CAP locations to store cartridges.
4. The robot uses the swap cell (the top-most cell in the reserved area) for in-
transit cartridges, to place a cartridge that is left in the hand-camera
assembly when a power failure occurs, or to perform a swap operation.
