successful if the physical volume is found in the expected storage cell or if it is
mounted currently on a physical drive in the VTS or TS7700 Virtualization Engine.
An audit operation for a volser that has been placed in an output facility fails
because the volser is no longer in the Library Manager’s inventory.
Audit operations are queued in the Library Manager and have a lower execution
priority than mounts. An audit operation is complete when validation of the
location of the specified volser has been attempted and the host has been notified
of the success or failure of the validation.
Import Operations
The Import operation allows one or more logical volumes from Exported Stacked
Volumes to be copied into a VTS. The Exported Stacked Volumes must be inserted
into the 3494 Tape Library by using the convenience I/O station. A list of logical
volumes to be imported must be provided as described in Appendix B,

When the Import operation completes,
Exported Stacked Volumes remain in the Import category. You can use the Manage
Import Volumes window for further disposition of the volumes (see Figure 151 on
page 251).
Export Operations
The Export operation allows logical volumes within a VTS to be copied to physical
Exported Stacked Volumes that can be removed from a 3494 Tape Library. The
logical volumes are deleted from the VTS and are no longer accessible in the VTS.
A destination for each logical volume may be specified in order to create one or
more Exported Stacked Volumes for a destination. Before executing the Export
operation, it is necessary to provide a list of logical volumes to be exported as
described in Appendix B,

Exported Stacked
Volumes may be ejected from the Export-Hold category by using the Manage
Export-Hold Volumes window (see Figure 153 on page 253).
Stand-Alone Operations
When a host cannot send mount commands to the 3494 Tape Library, it may
perform standalone operations by using standalone software. Some examples are
as follows:
Stand alone dump
The host must receive an initial program load (IPL) from tape, then dump
the host memory contents to a separate tape. The tape may be mounted
later under the control of a host.
Stand alone restore
The host must receive an IPL with a function to restore the contents of
DASD volumes from data that is stored on the tape volumes. After the
DASD volumes are restored, the host system may receive an IPL with
restored DASD volumes.
The two types of stand alone operations are:
Using automatic cartridge loader mode
The tape drives in the 3494 Tape Library do not have automatic cartridge
loaders. However, the 3494 Tape Library allows the automatic mounting of
the next cartridge of a predefined sequential set in a specified tape drive.
The 3494 Tape Library supports the following:
