Managing Media
Copying Media
Chapter 4146
target medium is selected to which the data will be copied. The target
media are selected from the same media pool as the source media, from a
free pool, or from the blank media in a library.
Selection and Use
of Devices
For each source medium, Data Protector selects a pair of devices from the
devices that you specified in the automated media copy specification. The
automated media copy functionality provides its own balancing. Data
Protector tries to make optimum use of the available devices by using as
many devices as possible and selecting local devices if they are available.
Devices are locked at the beginning of the session. The devices that are
not available at that time cannot be used in the session, as device locking
after the beginning of the session is not possible. Note that at least a pair
of devices must be available for each media type for the entire session to
complete successfully. If the minimum number of devices necessary for
the session cannot be locked, the session fails.
If a media error occurs, the device with errors will be avoided within that
automated media copy session. However, if there are no other devices
available, it will be reused.
Destination Pool
of the Copies
The source medium defines the destination pool of the target medium.
This means that the copied media will belong to the same pool as the
original media.
Data Protection of
the Copies
The default protection period for the copy is the same as the protection
for the original. You can set a different protection period when creating
or modifying the automated media copy specification.
Mount and
Cleanme Request
Handling
The automated media copy functionality does not handle mount or
cleanme requests. If a mount request is received, the media pair
concerned is aborted, but the session continues. You can manually copy
the media that were not copied after the automated media copy session
finishes.
For examples of use, refer to the HP OpenView Storage Data Protector
Concepts Guide.
