And DRAM (dynamic RAM) that serves as the main storage device
12, an SRAM (static RAM) 13 whose stored data is nonvolatile, and an IPL storing a boot program
An (initial program loader) 14, a storage control device 15, and an input control device 16 are installed.

A plurality of hard disk drivers 17, such as two or three, are connected to the above storage controller, and these hard disk drivers 17 are used as auxiliary storage devices and are stored in the SRAM 13 described above. A data table having the same contents as the multiplexing information table T stored therein is stored, and the data is multiplexed and managed.

It stores data (master operation, slave operation, disconnection operation, etc.), and data of programs and data copy status.

FIG. 3 shows the above-mentioned index data, which is the serial number data R of the installed model.
1 and the date, hour, minute and second data R to be updated to the data
Knit with 2. If the index data includes data indicating the number of updates, the number of updates can be determined by this data.

FIG. 4 shows a flowchart for determining the boot auxiliary storage device (hard disk driver 17 ...). This flowchart is stored in the SRAM 13 and is executed by the CPU 11 by a program.

That is, which one of the hard disk drivers 17 ...
When it is determined that one of 7 ... Is designated by the switch of the input device 20 (step n1, YES determination), the system is activated according to the designation (step n2).
That is, since the storage controller 15 connects the specified hard disk driver 17, the connected driver 1
In accordance with the boot program of the IPL 14 from 7 to 7, the program is read, stored in the DRAM 12 which is the main storage device, and activated.

When there is no designation by the switch in the above-mentioned step n1 (NO judgment), the SRAM 13 and the multiplexing information table T of each hard disk driver 17 ... Are read and the index data are compared and judged (step n3). .

Since all of the above-mentioned update of the multiplexing information table T is executed at the same time, if normal, the index data are all the same. Further, if at least two or more are the same data, it is basically considered that the hard disk of the same data stores correct data of the management information of the CPU 11.

When it is determined that two or more identical index data are stored as described above (step n4, YE
S determination), one of the hard disk drivers 17 determined to be the same is determined to be started, and auxiliary storage data is read from the hard disk of the hard disk driver 17 (step n5). If the disconnection is set for the hard disk driver 17 that does not match with, the driver 17 is disconnected (steps n6 and n7), and then the determined hard disk driver 17 is activated (step n8).

If it is judged in step n4 that the storage of two or more identical index data is not judged (NO judgment), since any hard disk driver 17 has a failure, these failures are removed and restoration is carried out. Therefore, the multiplexing information table T needs to be updated.

Therefore, it is judged whether or not the hard disk of the hard disk driver 17 to be restored has been initialized (step n9). Then, the hard disk is further initialized, a new multiplexing information table is updated to this, and the process proceeds to step n8 (steps n10 and n1).
