You can use four types of tape volumes to store objects:
- A group volume that is associated with an Object storage group
- A backup volume that is associated with an Object Backup storage
group
- An MVS scratch volume that, when added dynamically, appears as
belonging to an Object or Object Backup storage group when another
volume is needed by OAM to satisfy a request
- An OAM scratch volume that is associated with the *SCRTCH* Object
storage group. It is available to be used by any Object or Object
Backup storage group that uses the same unit name and data class as
this volume.
