BIOS1
2 starts the boot process of the OS 11 following the transmission of the architecture information (Step C3), the OS 11 performs the boot process of the system (Step D1), and then starts the operation process of the system (Step D2). ).

The dump system setting unit 3 of the controller 3
3 receives the architecture information from the BIOS 12, the architecture type storage field 5 of the entry corresponding to the system #A 1 in the dump method storage table 5
2 is set to the architecture A, and the dump notification method A for the architecture A is set to the dump notification method storage field 53 (step B1).

Similar processing is performed in the system # B2, and the architecture type storage field 5 of the entry corresponding to the system # B2 in the dump method storage table 5
2 is an architecture B, and a dump notification method storage field 53 is a dump method B for the architecture B.
Each method is set (step B1).

Next, during the system operation processing by the OS 11, a stall occurs in the OS 11 or the OS 12 for some reason (step D3). When the operator, maintenance personnel, etc. recognize the stall of the system, the dump button 4 is activated.
