Abstract

PURPOSE:To curtail the dump capacity in each adaptor unit by constituting the system so that in accordance with control from a controller, each adaptor checks information which becomes a dump object and informing the necessary dump capacity to the controller. CONSTITUTION:When a capacity display command is set to a command register 14, a processor 11 executes a parity check or a sum check to a ROM 12, and decides whither a stored program is normal or not. When it is decided that the check to the ROM 12 is normal, the capacity of a RAM 15 is set to a capacity display register 15 as a dump capacity. Also, when it is decided that the check to the ROM 12 is abnormal, that which is obtained by adding up the capacity of the ROM 12 and the capacity of the RAM 13 is set to the capacity display register 15 as the dump capacity. Accordingly, when there is no abnormality in the ROM 12 at the time of informing the dump capacity, each adaptor sets the capacity of only the RAM 13 as the dump capacity, by which the dump capacity can be curtailed remarkably.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dump processing system for sucking memory information or information in an adapter to an auxiliary storage device such as a disk device when an error occurs or the system goes down due to an error or other causes in an information processing apparatus. .

[0002]

Connected.

When the dump process is activated in such a configuration, the central processing unit 31 writes the logging data read from the internal memory 37 or the corresponding adapter into the logging area of the disk device 34 via the disk controller 35. This logging data is separately analyzed to clarify the cause of the error. In addition, when the central processing unit 31 performs dump processing for each adapter,
Since the amount of information differs for each adapter, it is necessary to know their capacity in advance.

[0005]

By the way, since the adapter in the information processing device changes according to the increase or decrease or change of the input / output device, the amount of information to be dumped by the central processing unit 31 also changes each time. Therefore,
In the conventional configuration, it is necessary for the central processing unit 31 to identify each of the adapters 33 ₁ and 33 ₂ in advance and individually grasp the amount of information (program and data) of each.

In the dump process, each adapter 3
3 _1, 33 all ₂ programs and data to which is loading into the disk device 34 as the logging data, the total amount was also become enormous depending on the number of adapters. That is, the capacity of the disk device 34 may become insufficient while the dump processing is sequentially performed for each adapter, and the dump processing may not be possible for all the adapters.

It is an object of the present invention to provide a dump processing system which enables reduction of dump capacity for each adapter.

[0008]

According to the present invention, there is provided information including a plurality of adapters for controlling an input / output device, and a control device for performing dump processing from a memory area of each adapter according to a predetermined dump capacity. In the processing device, each of the adapters includes a dump capacity notifying unit that checks the information to be dumped and notifies the required dump capacity to the control device according to the control from the control device. The dump processing is executed according to the dump capacity notified from each of the adapters.

[0009]

Since the control device can notify the connected adapters of the respective dump capacities in advance, it is possible to flexibly deal with the increase or decrease or change of the adapters.

Further, when each adapter notifies the dump capacity, by checking the information to be dumped, it is possible to judge whether static information such as a program is to be dumped. it can.
That is, the dump capacity can be reduced by presetting the required minimum dump capacity.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a block diagram showing an embodiment configuration of an adapter used in the dump processing system of the present invention. Note that the configuration of the adapter shown here shows only the part related to the implementation of the present invention.

In the figure, under the processor 11, a ROM 12 for storing a program, a RAM 13 for storing data, and a command register 14 for holding a capacity display command activated from a higher-level central processing unit (FIGS. 3 and 31). Also, a capacity display register 15 for holding the dump capacity notified to the central processing unit is connected.

The operation of the adapter of this embodiment will be described below with reference to FIG. 2 showing an example of the processing procedure in the processor 11. The processor 11 uses the command register 1
When the capacity display command is set in 4, the ROM 12 is subjected to a parity check or a sum check to determine whether or not the stored program is normal. If the check on the ROM 12 is determined to be normal, the capacity of the RAM 13 is set as the dump capacity in the capacity register 15. If the ROM 12 is determined to be abnormal, the capacity of the ROM 12 and RA
A sum of the capacity of M13 and the capacity of M13 is set in the capacity display register 15 as a dump capacity.

With such a configuration, the host central processing unit can be notified of the dump capacity from each adapter by issuing a capacity display command to each adapter at an appropriate timing. That is, the central processing unit can easily obtain the dump capacity of the adapter even when the adapter is newly installed.

Although the dump information in each adapter includes a program and data, the program is stored in the ROM 12
It is static information stored in and is relatively reliable. Therefore, if there is no abnormality in the ROM 12 (program) at the time of notifying the dump capacity described above, the RAM
By setting the capacity of only 13 (data) as the dump capacity, it is possible to significantly reduce the dump capacity.

[0016]

As described above, according to the present invention, the dump capacity at the time of dump processing can be appropriately controlled according to the situation of each adapter, so that the dump capacity can be significantly reduced. Further, it is possible to flexibly deal with the increase or decrease or change of the adapters, and the effect of reducing the dump capacity is extremely large especially when the number of the adapters increases.
