Internal Firmware Addressing Scheme
E-6 StorageTek SL3000 Library Guide
Rotational CAP Addressing
Column
The column value depends on the size of the library and the location of the module
that contains the CAP.
For modules to the left of centerline, the CAP column value corresponds to the second
column from the right of the module. For example, in a DEM, the column value for the
CAP would be -2 and a CEM to the left of the DEM would have a CAP column value
of -8.
For modules to the right of centerline, the CAP column value corresponds to the fifth
column from the left of the module. For example, a CAP in the Base has a column
value of 5 and a CEM to the right of the Base would have a CAP column value of 11.
Side
The side value is always 2, since the CAPs are only located on the front of the module.
Row
When addressing the device: the row value is 0.
When addressing a specific slot: the row value is the slot in the CAP magazine (values
1 to 26).
Example - Rotational Firmware Addressing
For this example, the library has a Base, DEM, and four CEMs (two on each side). The
address refers to the sixth slot down in the CAP in the CEM on the far left.
The firmware address is: (1, 1, -14, 2, 6)
AEM CAP Addressing
Column
The column value when referencing the CAP is:
■
-31 for left AEM
■
31 for right AEM
The column value when referencing a slot in the CAP:
■
-31 to -33 for left AEM
■
31 to 33 for right AEM
Side
Indicates the front or rear CAP doors on the library.
■
Rear wall = 1
■
Front wall = 2
Row
When addressing the device: the row value is 0.
When addressing a specific slot: the row value is the slot in the CAP (values 1 to 26).
Example - AEM CAP Firmware Addressing
For this example, the address is referencing a cartridge slot in the right AEM. The slot
is the 37th down in the far right column in the rear CAP door.
The firmware address is: (1, 1, 33, 1, 37)
