(2) Management CGMT 6 and data CG
MT7 discharge processing (see FIG. 1)

First, the terminal 4 sets the name of the CGMT library device 1 as the device name and the name of the management CGMT 6 as the medium name, and sets a CGMT ejection command (see FIG. 4B).
Is input, the command receiving means 21 of the CGMT library apparatus automatic operation system 2 receives a CGMT discharge command (step 201), and requests the command processing means 22 to perform processing (step 202).

The command processing means 22 analyzes the CGMT discharge command and requests the input / discharge means 23 to start the CGMT discharge job 11 because the requested processing is discharge of the management CGMT 6 (step 203).

The input / ejection means 23 extracts the job control language prototype (see FIG. 5) corresponding to the CGMT ejection command from the job control language file 8 and embeds the device name and the medium name in the CGMT ejection command to perform job control. After completing the language, the CGMT discharge job 11 is started (step 204).

The CGMT discharge job 11 is a management CGMT
6 is discharged from the CGMT library device 1.

The CGMT library device 1 manages the CGM
When T6 is discharged, a discharge completion message is sent to the command generation system 3.

(Step 20)
5) Request processing to the command processing means 22 (step 206).

The command processing means 22 analyzes the discharge completion notification command and requests the input / discharge means 23 to start the CGMT discharge job 11 because the requested processing is the discharge of the data CGMT 7 (step 207).

The input / discharge means 23 extracts the prototype of the job control language corresponding to the CGMT discharge command from the job control language file 8, reads one individual record subordinate to the common record from the management CGMT file 5, After the job control language is completed by embedding the exchange medium name, the CGMT discharge job 11 is started (step 208).

The CGMT discharge job 11 discharges data CGMT 7 of the first volume from the CGMT library device 1.

When the first volume of data CGMT 7 is discharged, the CGMT library device 1 sends a discharge completion message to the command generation system 3.

Upon receiving the discharge completion message, the command generation system 3 converts the discharge completion message into a discharge completion notification command with reference to the message / command correspondence table 13 and notifies the CGMT library device automatic operation system 2 of the command.

The command receiving means 21 of the CGMT library device automatic operation system 2 includes the command generation system 3
(Step 20)
9), request processing to the command processing means 22 (step 210).

The command processing means 22 analyzes the ejection completion notification command and determines that the requested processing is the next data CGMT.
Since the discharge is No. 7, the input / discharge unit 23 is requested to start the CGMT discharge job 11 (step 211).

The charging / discharging means 23 stores the data CGMT7
It is determined whether or not has been discharged to the number of transfer media (step 212), and if not, it is determined whether or not the discharge completion notification command is the corresponding CGMT absence notification command (step 213). If the discharge completion notification command is not the corresponding CGMT absence notification command, the input / output unit 23 returns the control to step 208.

The CGMT library apparatus automatic operation system 2 repeats steps 208 to 213 and discharges the second and subsequent data CGMTs 7 from the CGMT library apparatus 1, and when the number of data CGMTs 7 reaches the number of transfer media in step 212. , And the process ends. Data C
Even if the number of discharged GMTs 7 does not reach the number of exchange media, if the discharge completion notification command is the corresponding CGMT absence notification command in step 213, the excess / deficiency list 12 is output (step 214), and the process ends. .

(3) Failure processing (see FIG. 2)

When a failure such as head cleaning or access clear occurs in the CGMT library device 1,
The MT library device 1 sends a failure notification message to the command generation system 3.

Upon receiving the failure notification message, the command generation system 3 converts the failure notification message into a CGMT failure notification command by referring to the message / command correspondence table 13 and notifies the CGMT library device automatic operation system 2 of the command.

The command receiving means 21 of the CGMT library device automatic operation system 2
When a CGMT failure notification command is received from (step 301), the command processing unit 22 is requested to perform processing (step 302).

The command processing means 22 analyzes the CGMT failure notification command, and requests the failure processing means 25 to activate the CGMT failure recovery job 14 because the requested processing is the CGMT failure recovery processing (step 303).

The failure processing means 25 extracts the prototype of the job control language corresponding to the start command of the CGMT failure recovery job 14 such as the accessor clearing process and the head cleaning process from the job control language file 8, and reads the device in the CGMT failure notification command. After completing the job control language by embedding parameters such as the name and head name, the CGMT failure recovery job 14 is started (step 304).

The CGMT failure recovery job 14 cleans the head of the CGMT library device 1 in the case of head cleaning processing. In the case of the accessor clearing process, the CGMT of the CGMT library device 1 is returned to the cell or the input / output port.
