Tip: Most tape library management systems on z/OS use the dataset name to
identify tapes to be taken off-site. Tivoli Storage Manager uses the format
<prefix>.BFS for both on-site and off-site dataset names in one device class.
To choose another dataset name for off-site copies, create another device
class for the off-site copies and choose a different prefix. Set the tape library
management system to trigger on this off-site name, and off-site copies will be
identified automatically.
The command shown in Example 6-7 defines a device class named
LTO2-OFFSITE for library 3582LIB.

6.2.6 Defining a sequential file device class
Device classes that use a type of FILE allow a random access (disk) device to
simulate a sequential device. The most common uses for sequential file storage
pools are:
If your library has a single drive and you want to perform reclamation on
volumes in storage pools using this library. When you specify the reclamation
pool for the storage pools, it must be a primary sequential storage pool. To
use a disk for reclamation you must create a sequential file storage pool.
Creating database backups for keeping on-site and online.
To configure a sequential storage pool, you must first define a device class of
device type FILE. When defining the device class, you need to specify which
directory to use and what the maximum size of each volume can be. Volumes in
a sequential file storage pool are, of course, files. You can specify how big each
of these files can become before the Tivoli Storage Manager server closes one
and creates another.
