User recommendations
To avoid over-allocation of disk space and the possibility of running out of disk space for non-user
data:
• Only configure the libraries that you need
• Only configure the number of cartridges that you are likely to need
You can add cartridges at a later date to expand the system and remove individual blank cartridges
from a library without deleting the whole library, but cannot remove cartridges that have been written
to. See “Cartridges (Configuration)” on page 116.
Source and target libraries
Target libraries are created if you have a replication license when you create a replication mapping.
Source libraries are always visible to the host; Target libraries are not normally visible to the host, but
you can configure devices to make them visible to backup applications. This feature should be used
with care. See “Backup applications and target libraries” on page 82 for further details.
