When the library detects a new, unassigned cartridge, the library reads the
VOLSER and assigns the cartridge to the correct logical library. If the VOLSER
does not match any of the VOLSER ranges, the cartridge is available to be
imported into any logical library of the same media type. The assignment is then
determined by the first application to import the cartridge.
Within a physical TS4500 tape library, a maximum of 300 VOLSER ranges can be
created between all logical libraries.
VOLSER ranges are created during the initial library configuration. However, you
can assign new, or modify existing, ranges from the Logical Libraries page of the
TS4500 management GUI.
Increasing capacity
Install capacity on demand (CoD) features to increase the cartridge capacity of
frames in the TS4500 tape library.
In the TS4500 tape library, the physical capacity, or total storage slots, is composed
of licensed and unlicensed capacity. When the number of assigned cartridges
reaches the licensed capacity, more cartridges cannot be assigned to a logical
library until one of the following actions occurs:
v
A cartridge is removed
v
A CoD feature is purchased
v
More slots or frames are added to the library
The Intermediate, Base, and High-Density Capacity-on-Demand features provide
license keys so that you can enable more storage slots in the frames of the TS4500
tape library. For more information, see “Frame capacity” on page 109.
Monitor the capacity utilization of frames and the library from the TS4500
management GUI.
Intermediate and Base Capacity on Demand
Use the Intermediate and Base Capacity on Demand (CoD) features to increase the
initial (entry) capacity of the base frames (models L25 and L55) of the TS4500 tape
library.
The initial (entry) capacity of the L25 and L55 frames is 100 storage slots. You can
purchase CoD features to increase the amount of available licensed capacity.
The Intermediate CoD feature (FC 1643) adds 100 slots, increasing the usable
capacity of the L25 and L55 frames to 200 slots. The Base CoD feature (FC 1644)
adds 200 slots, increasing the usable capacity of the L25 and L55 frames to 400
slots. FC 1644 is referred to as Full CoD with the TS4500 tape library.
For more information about these licensed features, see “Feature codes for the
TS4500” on page 97. For more information about the capacities of library frames in
various positions and configurations, see “Frame capacity” on page 109.
High-Density Capacity on Demand
Use the High Density (HD) Capacity on Demand (CoD) license key to enable the
full high-density capacity of the Lx5, Dx5, and Sx5 frames in the TS4500 tape
library. Enabling the CoD on the TS4500 is a non-disruptive process.
