Abstract
A computer system includes a plurality of systems configured to be connected to each other by links and to operate synchronously each other. Each of said plurality of systems includes a fault tolerant controller, a CPU, a baseboard management controller and a plurality of hardware modules. The CPU is connected with the fault tolerant controller. The baseboard management controller is connected with the fault tolerant controller. The plurality of hardware modules is connected with the fault tolerant controller. When receiving a trouble which occurs in any of the plurality of systems, the fault tolerant controller outputs an interrupt regarding the trouble to at least one of the CPU and the baseboard management controller predetermined correspondingly to the trouble.
Claims20
A computer system comprising:
- a plurality of systems configured to be connected to each other by links and to operate synchronously each other,
- wherein each of said plurality of systems comprises:
- a fault tolerant controller,
- a CPU configured to be connected with said fault tolerant controller,
- a baseboard management controller configured to be connected with said fault tolerant controller, and
- a plurality of hardware modules configured to be connected with said fault tolerant controller,
- when receiving a trouble which occurs in any of said plurality of systems, said fault tolerant controller outputs an interrupt regarding said trouble to at least one of said CPU and said baseboard management controller predetermined correspondingly to said trouble.
A method for dealing with errors, comprising:
- (a) judging a cause and a kind of a trouble, when said trouble occurs in any of a plurality of systems included in a computer system, wherein said plurality of systems is connected to each other by links and operates synchronously each other;
- and
- (b) outputting an interrupt regarding said trouble to at least one destination predetermined correspondingly to said kind of said trouble.
