this ®eld displays the frame number. For a LAN-attached VTS,²B18² is

 

displayed since the VTS processor is in a rack not attached to the library

 

frames.

Exp/Imp Capable

 

If the VTS is Import/Export capable, this ®eld will be²Yes².

VTS Port

 

This is the Library Manager port used to communicate with the VTS. For an

 

ARTIC-attached VTS this is ARTIC port 0. For a LAN-attached VTS this is

 

the LAN port number which starts at 0x10. If the Library Manager has

 

initialized with the port, the port's number is displayed. If it is not initialized

 

a dash (-) is displayed.

Physical Device Ports

 

These are the Library Manager ports used to communicate with the

 

physical devices associated with the VTS. For an ARTIC-attached VTS

 

there is one port for each physical drive. For a LAN-attached VTS there is

 

only one port used to communicate with all of the VTS physical drives. If

 

the Library Manager has initialized with a port, the port's number is

 

displayed. If it is not initialized a dash (-) is displayed.

Virtual Device Ports

 

These are the Library Manager ports used to communicate with the virtual

 

devices associated with the VTS. There is one port for each virtual

 

subsystem of 16 drives. An ARTIC-attached VTS has 2 virtual subsystems.

 

A LAN-attached VTS can have either 2 or 4 virtual subsystems. If the

 

Library Manager has initialized with a port, the port's number is displayed. If

 

it is not initialized a dash (-) is displayed.

VTS Primary IP Address

 

This is only displayed for a LAN-attached VTS. This is the IP address of the

 

Library Manager which is used by the VTS processor to communicate with

 

the Library Manager.

The VTS Status window has the following buttons:

OK

Closes the VTS Status window.

Help
