Abstract

PURPOSE:To use peripheral processors as usual without shutting off a system at the time of starting the system even when a fault is occurred in an I/O controller connecting the peripheral processors. CONSTITUTION:When the system is started up in a state where an input/output controller 3a is in the fault, a trouble reporting means 5 reports the troubled I/O controller 3a to a central processing unit 1. The central processing unit 1 instructs a system structure information definition eliminating means 6 to eliminate the structure definition of a peripheral processor 4a connected to the I/O controller 3a from system structure information 2.

[Prior Art] In a conventional information processing device, connections of peripheral processing devices are defined in advance using system configuration information, and firmware corresponding to each subsystem is loaded into an input/output control device according to this system configuration information. Startup processing is being executed.

[0003] If the input/output control device for connecting the peripheral processing device defined in the system configuration information is out of order, the system detects the error during startup, reports the error, and restarts the system. The uploading process may be interrupted.

Referring to FIG. 1, the operation of the device that deletes the definition of system configuration information due to a failure of the input/output control device will be described.

Among the plurality of input/output control devices 3a to 3c,
When an attempt is made to start up the system in a state where the input/output control device 3a has failed, the failure reporting means 5 reports the input/output control device 3a in which the failure has occurred to the central processing unit 1. Having received the report, the central processing unit 1 instructs the system configuration information definition deletion means 6 to delete the configuration definition of the peripheral processing device 4a connected via the input/output control device 3a from the system configuration information 2. Give instructions. The system configuration information definition deletion means 6 deletes the peripheral processing device 4a from the system configuration information 2.
, and reports the deletion to the central processing unit 1.

[0015] As a result, no access is made to the input/output control device 3a, and the system starts up with the peripheral processing device 4a disconnected.

Next, referring to FIG. 2, the operation of the device that masks the definition of system configuration information due to a failure of the input/output control device will be explained.

Among the plurality of input/output control devices 3a to 3c,
When an attempt is made to start up the system in a state where the input/output control device 3a has failed, the failure reporting means 5 reports the input/output control device 3a in which the failure has occurred to the central processing unit 1. Having received the report, the central processing unit 1 instructs the system configuration information definition masking means 7 to mask the definition in the system configuration information of the peripheral processing unit 4a connected via the input/output control unit 3a. issue. The system configuration information definition masking means 7 includes the peripheral processing device 4a in the system configuration information.
Mask the definition of input/output control device 3 during startup.

Having received the report, the central processing unit 1 sends the definition in the system configuration information of the peripheral processing unit 4a connected via the input/output control unit 3a to the system configuration information definition change means 8 as a spare input/output An instruction is issued to the control device 9a to switch.

The input/output control device 3a and the spare input/output control device 9a are connected to the peripheral processing device 4a by a daisy-chained interface cable 10a, and each interface driver 13a, 19a is connected to the peripheral processing device 4a using system configuration information. In the initial state, the interface driver 13a is in an operable state and the interface driver 19a is in an inoperable state.

The system configuration information changing means 8 changes the definition of the peripheral processing device 4a in the system configuration information to the input/output control device 3.
Change the connection from a to the backup input/output control device 9a. At the same time, the interface driver 13a becomes inoperable, and the interface driver 19a
Since the peripheral control device 4a becomes operational, the peripheral control device 4a is connected to the system via the input/output control device 9a.
