Using multiple logical libraries
You can create multiple logical libraries by partitioning the physical library's tape drives and tape cartridges into two or more logical libraries. Each logical library can contain only one media type.
Create multiple logical libraries for the following scenarios:
- Share the library for multiple backup applications
- You can partition your library so that it processes commands from Application 1 (about Department A) in Logical Library 1, commands from Application 2 (about Department B) in Logical Library 2, and commands from Application 3 (about Department C) in Logical Library 3. In this configuration, the tape drives and tape cartridges in each logical library are dedicated to that library and are not shared among other libraries. Commands issued by the applications travel to the library through three unique control paths. Thus, the data processing for Department A is confined to the tape drives and tape cartridges in Logical Library 1, processing for Department B is confined to the tape drives and tape cartridges in Logical Library 2, and so forth.
- Share the library to support mixed drive types for any application
- You can use multiple logical libraries for applications that do not support mixed drive types and media in the same logical library by partitioning the physical tape library to keep them separate. For example, you can partition LTO 6 and LTO 5 tape drives and their media into two separate logical libraries.
Tip: When naming logical
libraries, developing an enterprise-wide library naming convention
leads to easier management of the libraries.
