Internal Library Addressing Scheme
Library Addressing Reference C-3
■
13-slot arrays on the outer walls
Special Arrays
■
8-slot arrays above the pass-thru port
■
8-slot arrays under the stop brackets for the service safety door
■
4-slot arrays on the elevators and pass-thru ports
■
3-slot arrays at the ends of each rail
■
12-slot arrays for bulk CAP magazine
Rails (LSMs)
Each library has four robotic rails. For HLI addressing, each of these rails is considered
a library storage module (LSM).
Columns (Panels)
Columns (equivalent to panels in HLI-PRC addressing) refer to the horizontal location
of a component in the library (similar to the columns in a spreadsheet). Special
columns include:
■
Corners because there is no inner wall
■
Pass-thru ports because the top six slots are inaccessible because of the PTPs
■
Pass-thru port panels because the top cartridge slot (under the port) is reserved as
a redundant robotics drop-off slot (two for each rail, one on each side)

Internal Library Addressing Overview
Internal library addressing designates location using Library, Rail, Column, Side, Row
(L,R,C,S,W).
■
Library — the number of the library within a library complex (always 1 for a
single library)
■
Rail — robotic rails numbered top down from 1 to 4.
■
Column — the horizontal location of a device or slot. Column numbering begins
at the center of the drive bays and incr1 to the right or -1 to the left as you
move toward the front of the library:
– +1 is just right of the center of the drive bays.
– -1 is just to the left of center of the drive bays.
– The first columns containing tape cartridges are +3 and -3.
