During the storage management cycle, OAM determines whether the
primary copy of an object is correctly positioned in the OAM storage
hierarchy. If the object is not correctly positioned in the OAM storage
hierarchy, the primary copy of the object is moved to the correct
storage medium. One of the following medium transitions can be performed
for the primary copy of an object:
- Disk sublevel 1 to disk sublevel 2
- Disk sublevel 1 to optical
- Disk sublevel 1 to tape sublevel 1
- Disk sublevel 1 to tape sublevel 2
- Disk sublevel 2 to disk sublevel 1
- Disk sublevel 2 to optical
- Disk sublevel 2 to tape sublevel 1
- Disk sublevel 2 to tape sublevel 2
- Optical to disk sublevel 1
- Optical to disk sublevel 2
- Optical to tape sublevel 1
- Optical to tape sublevel 2
- Tape sublevel 1 to disk sublevel 1
- Tape sublevel 1 to disk sublevel 2
- Tape sublevel 1 to optical
- Tape sublevel 1 to tape sublevel 2
- Tape sublevel 2 to disk sublevel 1
- Tape sublevel 2 to disk sublevel 2
- Tape sublevel 2 to optical
- Tape sublevel 2 to tape sublevel 1
The location of an object in the hierarchy is unknown to the user
of the programming interface. You do not need to supply device-dependent
information. For example, there are no JCL DD statements and no requirements
for device geometry, such as track size.
