Transparent addition or removal of storage capacity

With the Advanced Library Management System (ALMS), you can change the quantity of storage slots accessible to all logical libraries by adding licensed capacity or by adding physical capacity. The change is transparent to each host application because the value in the Maximum Number of Cartridges field on the management GUI is not impacted by changes to the quantity of storage slots. The additional storage slots are new candidates for cartridges to be moved to upon insertion. This behavior allows the following two tasks to be performed independently and in either order:

• An administrator or service task to change the licensed or physical capacity of the library
• An administrator task to prepare the application to have access to more cartridges in their respective logical libraries by increasing the Maximum Number of Cartridges on the management GUI . Then, rediscovering the logical library at the application (for example, by restarting the application).
