Operator Interface

The library manager console is used to perform the setup, management, and status functions needed to support a Virtual Tape Server subsystem.

 

Logical Volume Inventory

 

The data base in the library manager is expanded to handle the large number of

 

logical volumes that a Virtual Tape Server subsystem uses. There are also new

 

operator functions which allow the addition of logical volumes by specifying a

 

volume serial number range through the library manager console (refer to Figure 95

on page 164).

VTS Import/Export Overview

Import/Export Operations

The Import and Export operations provide a way to move logical volumes out of a

VTS subsystem to physical cartridges called Exported Stacked Volumes and to

return them to the same or move them to another VTS. Lists of volumes for Import

or Export are provided to a VTS on logical volumes called the Import List Volume or

the Export List Volume, which are resident in the VTS. The Status File on the

Import or Export List Volume provides status for each logical volume being

processed. See ªAppendix B. Virtual Tape Server Import/Export Advanced Functionº

on page 307 for information about preparing the Import or Export List Volume.

Import

The Import operation allows logical volumes which are stored on physical Exported

Stacked Volumes to become logical volumes within a Virtual Tape Server. A speci®c

volume or all volumes may be imported from Exported Stacked Volumes which

have been entered into a library through the Convenience Input¤Output Station and

have been moved to the Import category by an operator at the Library Manager

console. Host console messages provide status on progress and completion of the

Import operation.

Export

The Export operation allows customer data on logical volumes in a Virtual Tape

Server to be removed from the VTS onto physical Exported Stacked Volumes. The

list of volumes to export and a destination for each volume is provided by the host

operator or tape management system. Logical volumes with the same destination

are grouped on the same Exported Stacked Volume and this physical volume is

then moved into a category which allows an operator at the Library Manager

console to eject the cartridge through the Convenience Input¤Output Station for

storage outside the library or movement to another tape library to be imported into a

VTS. Host console messages provide status on progress and success of the Export

operation.

Local and Remote Power Control

The local power is controlled by the operator using a switch at the operator control panel. See ªChanging from Local to Remote Powerº on page 76 and ªChanging from Remote to Local Powerº on page 76 for operating instructions.
