Internal Library Addressing Scheme
C-4 StorageTek SL8500 User's Guide
■
Side — indicates the inner and outer wall, left or right robots, or left or right
rotational CAP.
– Outer wall =1, Inner wall =2
– Left robot =1, Right robot =2 (in non-redundant robotics the side is always 1)
– Right rotational CAP =1, Left rotational CAP =2 (for Bulk CAPs the side is
always 1)
■
Row — The vertical location of a device or slot. Rows are consecutively numbered
from the top (1) down (to 13 outer wall and 14 inner wall).
Components (such as CAPs, elevators, PTP, and robots) have unique addressing rules:
■
A row value equal to 0 indicates the address is referring to the device, not a slot in
the device.
■
The side value may not directly correlate to inner and outer walls.
■
The column value of elevators and CAPs depends on the number of storage
expansion modules in the library.
Drive Internal Library Addressing
Drives always have a column value between -2 and 2, a side value of 1, and a row
value between 1 and 4.

Rail and Row :
– When numbering the device, the rail value is 2 and the row value is 0.
