Understanding location coordinates
This section describes the coordinate addressing system that the library uses to indicate the location
of cartridges and drives in the library.
You can use the Library Explorer feature to view a graphical presentation of all the drives, cartridges,
and slots in the library. The Library Explorer can display all library elements according to physical
location in any configuration, from 1 to 17 cabinets (called modules), and 1 drive up to the
maximum number of 192 drives. See
“Using Library Explorer” (page 107)
.
NOTE:
For libraries shipped before May 2013 and running firmware versions before 663H, the
ESL G3 can have up to 12 modules, but only the first 8 can have drives. Drives must be installed
in bottom to top order in the control module, filling the module with 12 drives, before any are
added to the first expansion module (EM). Additionally, the first EM must have all 12 drives installed
in the same order before adding any to next EM.
For libraries shipped after May 2013 or for libraries which upgraded using the Controller Board
Upgrade Kit (running library firmware version 663H or later), drives can be installed throughout
the library and across all EMs consecutively or non-consecutively, as long as the control module
contains at least one drive. However, drives should still be added to the CM and any additional
EMs in bottom to top order.
Cartridge locations
The library uses a coordinate addressing system that indicates the location of cartridges using six
coordinates. The coordinates are represented by the library in 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 will always be 1.
•
Module - for the purposes of this coordinate addressing system, the modules are numbered
from 0 to 16, where 0 is the left parking module, when applicable.
•
Rack - there are 2 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.
•
Column - there are 4 columns in a rack, numbered from left to right as you face the front of
the rack. These are numbered from 1 to 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 from 1 to 6 for LTO cartridges.
