Abstract

An information processing device includes a plurality of communication units and a processor. Each of the plurality of communication units has a plurality of ports and is replaceable. The processor is configured to execute a process. The process includes specifying an active port mounted on one of the communication units on which a faulty active port is also mounted and switching the active port specified at the specifying to a standby port.

Claims (19)

1. An information processing device comprising:

a plurality of communication units that each includes a plurality of ports and is replaceable;

a memory that stores addresses assigned to active ports among addresses assigned to ports, each of the addresses including a bus identifier that identifies a bus to which a communication unit is connected, a device identifier that identifies a device connected to a same bus, and a function identifier that identifies a function provided by a same device; and

a processor coupled to the memory, the processor executes a process including:

searching ports each of which is assigned with an address including a bus identifier that is a same bus identifier included in an address assigned to the faulty active port, the searching determining whether a device is present at each of the searched ports;

specifying, among the searched ports at each of which a device is determined to be present at the searching, a port, as an active port mounted on one of the communication units on which a faulty active port is also mounted, assigned with an address stored in the memory; and

switching the active port specified at the specifying to a standby port.

2. The information processing device according to claim 1 , wherein the switching includes switching the active port specified at the specifying to a standby port, and switching a standby port mounted on a communication unit different from the communication unit that includes the active port, to a new active port.

3. The information processing device according to claim 1 , wherein

the communication unit includes an LED that indicates whether communication is performed via each port, the process further including,

turning on the LED of the communication unit that includes the faulty active port at a certain pattern, when the active port specified at the specifying is switched to a standby port at the switching.

4. A non-transitory computer-readable recording medium storing an information processing program that causes a computer to execute a process comprising:

searching, among a plurality of communication devices that each includes a plurality of ports and is replaceable, ports each of which is assigned with an address including a bus identifier that is a same bus identifier included in an address assigned to the faulty active port, the searching determining whether a device is present at each of the searched ports, the address including a bus identifier that identifies a bus to which a communication unit is connected, a device identifier that identifies a device connected to a same bus, and a function identifier that identifies a function provided by a same device;

specifying, among the searched ports at each of which a device is determined to be present at the searching, a port, as another active port mounted on one of the communication units on which a faulty active port is also mounted, assigned with an address stored in a storage unit storing addresses assigned to active ports among addresses assigned to ports; and

switching the specified active port to a standby port.

5. A port control method comprising:

searching, among a plurality of communication devices that each includes a plurality of ports and is replaceable, ports each of which is assigned with an address including a bus identifier that is a same bus identifier included in an address assigned to the faulty active port, by a processor, the searching determining whether a device is present at each of the searched ports, the address including a bus identifier that identifies a bus to which a communication unit is connected, a device identifier that identifies a device connected to a same bus, and a function identifier that identifies a function provided by a same device;

specifying, among the searched ports at each of which a device is determined to be present at the searching, a port, as another active port mounted on one of the communication units on which a faulty active port is also mounted, assigned with an address stored in a storage unit storing addresses assigned to active ports among addresses assigned to ports, by the processor; and

switching the specified active port to a standby port, by the processor.
