132 Installing Cartridges
Storage Addressing System Overview
The library uses a coordinate addressing system that defines the location of cartridges using six
coordinates. The coordinates are represented by the library in a comma separated list. For example:
Each of the variables are explained in the following bulleted list:
• Aisle - There is only one aisle in the library. This value will always be 1.
• Module - There are from one to twelve modules, the control module and up to eleven expansion
modules. The value will be between 1 and 12.
• Rack - There are two rack designations inside each module. These will always be either 1 or 2, with
2 being the inside of the access door.
Figure 16 Aisle, Module, and Rack Numbering Locations
• Section - There are 10 sections in a rack, numbered from top to bottom as you face the rack.
• Column - There are four columns in a rack, numbered from left to right as you face the rack. These
are numbered between 1 and 4.
• Row - This is equal to one cartridge slot. The number of rows per section can vary depending on
the size of the cartridge. The rows are numbered between 1 and 6 for LTO cartridges and 1 and 5
for DLT cartridges.
