PROCESSING DEVICE, FAILURE RECOVERY METHOD THEREFOR, AND FAILURE RESTORATION METHOD

摘要

PROBLEM TO BE SOLVED: To reduce a cost required for multiplexing and to reduce recovery work time due to a failure.;SOLUTION: This processing device includes: a processor 101 which executes first and second pieces of control software SW1 and SW2 in a memory 131 to perform processing; and a device 1 having a plurality of SLOTs 1 to 8 to electrically connect the processor to a plurality of devices. The device 1 switches a SLOT which connects devices 2 and 3 between a SLOT 1 or 2 and a spare SLOT 8 allocated in advance through a switch 181. The processor 101 executes the first and second pieces of control software SW1 and SW2 to manage SLOT information 143 including pieces of path information obtained through the SLOTs 1, 2, and 8 between the devices 1 and 2 such that the SLOT information can be registered and updated. When a failure occurs in the SLOT 1 or 2, the processor 101 updates the path information obtained through the SLOT 1 or 2 into the path information obtained through the spare SLOT 8, and the SLOT which connects the devices 2 and 3 is switched from the SLOT 1 or 2 to the spare SLOT 8.;COPYRIGHT: (C)2007,JPO&INPIT
