IBM Magstar 3494 Export Operations, Import Operations, Stand-Alone Operations, Stand-alone dump

If the volser speci®ed is a logical volume in the library manager's inventory, the

library manager determines the physical volume the logical volume resides on and

performs an audit of that physical volume. The audit operation is successful if the

physical volume is found in the expected storage cell or if it is currently mounted on

a physical drive in the Virtual Tape Server.

An audit operation for a volser that has been placed in an output facility of the

library will fail 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 speci®ed volser has been attempted and the host has been noti®ed of the

success or failure of the validation.

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 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 speci®ed in order to create one or more Exported

Stacked Volumes for a destination. Prior to executing the Export operation, it is

necessary to provide a list of logical volumes to be exported as described in

ªAppendix B. Virtual Tape Server Import/Export Advanced Functionº on page 307.

Exported Stacked Volumes may be ejected from the Export-Hold category by using

the Manage Export-Hold Volumes pop-up window, shown in Figure 132 on page 206

.

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 library by using the Convenience Input¤Output Station and a list of logical

volumes to be imported must be provided as described in ªAppendix B. Virtual Tape

Server Import/Export Advanced Functionº on page 307. Exported Stacked Volumes

remain in the Import category upon completion of the Import operation for further

disposition by an operator using the Manage Import Volumes pop-up window,

Figure 130 on page 204.

Stand-Alone Operations

Stand-alone operations may be performed by using stand-alone software when a

host cannot send mount commands to the library. Some examples are as follows:

Stand-alone dump

The host must receive an initial program load (IPL) from tape, and then

dump the host memory contents to a separate tape. The tape may then 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 stored on the tape volumes. After the DASD

volumes are restored, the host system may receive an IPL with restored

DASD volumes.

Following are the two types of stand-alone operations:
