HLI Addressing Overview
HLI-PRC addressing designates physical location using: LSM, Panel, Row, and
Column.
LSM
Always equal to 0.
Panel
Indicates the front wall (CAP side) or rear wall (drive side) of a module. The panel
number can range from 0 to 23 depending on the configuration of the library.
■
Rear wall = even numbers
■
Front wall = odd numbers
The panel location is defined relative to the Base Module (panels 12 and 13). Panel
values less than 12 indicate the module is to the left of the Base Module, while values
greater than 13 indicate the module is to the right of the Base Module.
Base Module
■
Panels 12 and 13
DEM
■
Panels 10 and 11
CEM
■
Panels are numbered consecutively from the adjacent module. However, if there is
no DEM, a CEM placed directly to the left of a Base Module contains panels -8 and
-9 (panels -10 and -11 are skipped).
AEM
■
AEMs are considered CAPs by HLI addressing. Therefore, AEMs have a CAP ID
instead of a panel number (see
"HLI Addressing of CAPs" on page E-8)
■
Left AEM CAP ID is always numbered 0
■
Right AEM CAP ID is always numbered 11
Row
The vertical location of a slot, consecutively numbered from the top down (0 to 51).
However, drive bays have row numbering from 0 to 23 for the Base Module, and 0 to
31 in the DEM.
Column
The horizontal location of a slot from left to right (0 to 5). However, drive bays always
have a column value of 0 (see
"Tape Drive Hardware Numbering" on page E-15").
AEM column numbering starts at the rear wall and runs left to right (columns 0–2),
then proceeds to the front wall and runs left to right (columns 3–5).
