Cartridge Locations
The library uses a coordinate addressing system that indicates the
location of cartridges using six coordinates. The coordinates are
represented by a comma-separated list.
For example:
1,1,1,1,2,1 = aisle 1, module 1, rack 1, section 1, column 2, row 1
The following list explains each location variable:
• Aisle — There is only one aisle in the library. This value is always 1.
• Module — There can be up to 12 modules in a Gen 1 single-
robotics library (control module plus up to 11 expansion modules.
For a Gen 2 single robotics library, there can be up to 12 modules as
well. However, these modules can be standard or high-density
expansion modules. For a Gen 2 dual-robotics library, there can be
up to 17 modules in (left parking module, control module, right
parking module, and up to 13 standard or high-density expansion
modules).
Modules are numbered from left to right as you look at the front of
the modules The control module is always module 1. In dual-
robotics libraries, the left parking module, located to the left of the
control module, is module 0.
• 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.
• 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. For
an HDEM, there are ten (10) rotating columns.
• 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.
Note: Tape drives that are installed in rack 1 of a control module or an
expansion module replace storage in columns 1 and 2. Because
drives are installed from the bottom of the rack to the top, you
lose the storage starting in section 10 first. You do not lose the
magazine in columns 1 and 2 of section 5.
