When 3590 subsystems are attached to the 3494, the following 3590 functions change:

Drive control

The loading and unloading of volumes is controlled by the library manager. The 3590 subsystem communicates with the library manager to update the database with the drive status and cartridge location information.

Message displays

The library manager controls which messages are displayed to prevent the messages from getting out of synchronization with the library manager during Manual mode operations.

Attention interrupt

The library manager can use the communication path to the 3590 Model

A00 subsystem to send information to the host.
