Offline Volume Management
This section describes how to eject a volume in the user area from a library and
then manage it.
When you perform offline management on a volume, data recorded in this
volume becomes not accessible online. However, by adding new media, you can
use this system to manage far more tapes than the number of slots of the
libraries. When data stored in a volume in offline management is accessed, a
data read error occurs. However, when this volume is added in the library again,
data read of the volume becomes possible again.
Note
The number of volumes that can be managed by offline volume management is
500 per library, including volumes in the library.
