Configuring › Expanded Access Server for Tape and Robotics › Internal Operation

Internal Operation

The server receives requests for data blocks on tape to be for printing or browsing. The requested data blocks are handled as follows:

• If the data blocks are cached in memory, the server transfers those blocks using cross memory.
• If the data blocks are not already in memory, the server either reads the already mounted tape or mounts the tape.

If no drive is available to the server, the least recently referenced tape, which has also been mounted for at least a minimum amount of time (MINIDLE parameter) is dismounted.

If a tape has been idle for a maximum amount of time (MAXIDLE parameter), it is dismounted automatically to free the drive for CA View or any other application.

Note: Drives are not dedicated to the server.
