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

1. An information processing device comprising:

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

a processor configured to execute a process including;

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.

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

each of the ports is assigned with an address including a bus identifier that identifies a bus to which the communication unit is connected, a device identifier that identifies a device connected to the same bus, and a function identifier that identifies a function provided by the same device, the process further including

storing the address assigned to the active port, and

searching a port that is assigned with an address including a bus identifier that is same as a bus identifier included in an address assigned to the faulty active port, wherein

the specifying includes specifying a port assigned with the address stored at the storing among ports searched at the searching.

3. 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.

4. 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.

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

specifying, among a plurality of communication devices that each includes a plurality of ports and is replaceable, another active port mounted on one of the communication devices on which a faulty active port is also mounted; and

switching the specified active port to a standby port.

6. A port control method comprising:

specifying, among a plurality of communication devices that each includes a plurality of ports and is replaceable, another active port mounted on one of the communication devices on which a faulty active port is also mounted, by a processor, and

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