Control apparatus, storage apparatus, and non-transitory computer-readable recording medium having stored therein control program
First Claim
1. A control apparatus for one of a plurality of control apparatuses that controls accesses to a plurality of storage devices, the control apparatus comprising:
- a memory; and
a processor coupled to the memory, and the processor;
receives information on an abnormality in a relay apparatus comprising first and second monitor controllers provided in the relay apparatus that relays a communication among the plurality of control apparatuses, from the first monitor controller that manages first management information and execute a monitor of the relay apparatus, the abnormality being detected by the first monitor controller; and
when the received information about the abnormality is information on an abnormality of a bridge board that forms a first communication route between the first monitor controler and the second monitor controller that manages second management information and executes a monitor of the relay apparatus, executes a switching process for switching a communication route used to synchronize the first and second management information between the first monitor controller and the second monitor controller, from the first communication route via the bridge board, to a second communication route via communication lines connecting the control apparatus and either of the first and second monitor controllers.

Abstract
A control apparatus receives information on an abnormality in a relay apparatus including first and second monitor units provided in the relay apparatus to relay a communication among control apparatuses, from the first monitor unit to manage first information and execute a monitor of the relay apparatus, the abnormality being detected by the first monitor unit; and when the received information is information on an abnormality of a bridge unit to form a first communication route between the first monitor unit and the second monitor unit to manage second information and execute a monitor of the relay apparatus, executes a process for switching a communication route used to synchronize the first and second information between the first and second monitor unit, from the first communication route via the bridge unit, to a second communication route via communication lines connecting the control apparatus and the first and second monitor units.

8. A storage apparatus comprising:
-
a plurality of control apparatuses that control accesses to a plurality of storage devices; and a relay apparatus that relays a communication among the plurality of control apparatuses, the relay apparatus comprises; a first monitor controller that manages first management information and executes a monitor of the relay apparatus; a second monitor controller that manages second management information and executes a monitor of the relay apparatus; and a bridge board that forms a first communication route between the first monitor controller and the second monitor controller, and one control apparatus of the plurality of control apparatuses executes a switching process for switching, when receiving information on an abnormality of the bridge board detected by the first monitor controller from the first monitor controller, a communication route used to synchronize the first and second management information between the first monitor controller and the second monitor controller, from the first communication route via the bridge board, to a second communication route via communication lines connecting the control apparatus and either of the first and second monitor controllers. - View Dependent Claims (9, 10, 11, 12, 13)

14. A non-transitory computer-readable recording medium having stored therein a control program for causing one of computers that control accesses to a plurality of storage devices, to execute the process comprising:
-
receiving information on an abnormality in a relay apparatus comprising first and second monitor controllers provided in a relay apparatus that relays a communication among the plurality of computers, from the first monitor that manages first management information and executes a monitor of the relay apparatus, the abnormality being detected by the first monitor controller; and when the received information about the abnormality is information on an abnormality of a bridge board that forms a first communication route between the first monitor and the second monitor controller that manages second management information and executes a monitor of the relay apparatus, executing a switching process for switching a communication route used to synchronize the first and second management information between the first monitor controller and the second monitor controller, from the first communication route via the bridge board, to a second communication route via communication lines connecting the computer and either of the first and second monitor controllers. - View Dependent Claims (15, 16, 17, 18, 19)
