latest copy export had the entries of the volumes as not empty. You should bring the emptied copy
exported volumes to the library after you confirm they are empty on copy export status file at next copy
export.
3. The copy exported physical volumes continue to be managed by the source TS7700 in terms of space
reclamation. You can allow the TS7700 to determine when to reclaim a copy export physical volume or
you can manually cause a volume to be reclaimed. See the section on Reclamation of Copy Exported
Physical Volumes.
4. The current copy export functionality allows the host to mark a subset of volumes to either be
immediately ejected to the IO station or be held in the library so that they can be ejected from the library
at another time. The second option allows the user to determine a better time to retrieve these volumes
from the library without them sitting in the IO station. For customers running 8.21.x.x code or higher,
they have the option to re-insert volumes in the held state without removing them from the library. For
customers running pre 8.21.x.x in order to re-insert a held volume it needs to be ejected first.
General Considerations for Copy Export:
Here are some general considerations that you will need to be aware of in using the copy export function of
the TS7700:
1. The library associated with the TS7700 executing the copy export operation must have an I/O station
feature for the operation to be accepted. You should empty the I/O station prior to executing copy export
and avoid having it get into the full state.
2. On systems running pre 8.5.x.x code, the Import/Export function must have been enabled on the library
manager for copy export operations to be performed. A service representative uses the Enable/Disable
function of Utilities on the Service menu to do this.
3. Only one copy export operation can be performed at a time.
4. During the execution of a copy export operation, if the TS7700 cannot access the primary copy of a
logical volume and the secondary copy exists in a pool defined for copy export, regardless of whether
that pool is involved in the current copy export operation, TS7700 can’t access the secondary copy and
will fail the mount. When a copy export operation is not being performed, if the primary copy of a
logical volume cannot be accessed and the secondary copy exists, the secondary copy is accessed and a
new primary copy is created.
5. Copy export and insertion of logical volumes are mutually exclusive functions in a TS7700 or Grid.
6. The export list file volume cannot be assigned to the secondary copy pool that is specified for the
operation. If it is, the copy export operation will fail.
7. A minimum of four physical tape drives must be available to the TS7700 for the copy export operation
to be performed. The operation will be terminated by the TS7700 when fewer than four physical tape
drives are available. Processing for the physical stacked volume in progress when the condition
occurred will be completed and the status file records will reflect what was completed before the
operation was terminated.
8. If a scratch physical volume is needed during a copy export operation, the secondary physical volume
pool must have an available scratch volume or access to borrow one for the operation to continue. If a
scratch volume is not available, the TS7700 will indicate this through a console message and wait for up
to 60 minutes. If a scratch volume is not made available to the secondary physical volume pool within
60 minutes, the copy export operation is terminated.
