IPC: G06F12/08
Filed: 1988-08-03
Abstract: PURPOSE:To avoid a stoppage of operation of a system by reading data out of a cash register CAR and transferring them to a storage circuit in case the transmission of the data on the CAR to the storage circuit is impossible. CONSTITUTION:When the processors 4 and 5 and a fault processor 53 have accesses to a storage device 1, a storage controller 2 gives an access to a CAR21 when the corresponding address is included in the CAR21 and no access is given to the storage device 1. If the relevant address is not included in the CAR21, the address is read out of the storage device 1 and written into the CAR21. When this address is rewritten into another address by the CAR21, this new address is written into the storage device 1. In the case the controller 2 has a fault, the latest data is written into the storage device 1 since this data is included in the CAR21. Then the storage device 1 is logically separated from the controller 2, and the storage device 1 is logically connected to a storage controller 7. Thus the operation is started again with exclusion of the controller 2 and processors 4 and 5.
