Abstract

PURPOSE:To improve the data processing efficiency by constituting the system that other keyboard is used when a keyboard used as a console is failed. CONSTITUTION:In keyboard display devices 10-0-10-n, logical 1 is set to sections 11-0-11-n corresponding to an operating state command section 11 when the operation is normal for example, and logical 0 is set thereto when the operation is not normal. When the device 10-0 used as a console is inoperative in this case, since 0 is set to the section 1-0, a normality deciding section 12 outputs 0 to turn off an AND circuit 18. An AND circuit 19 is set in this case. The deciding section 12 reads in this case other sections 11-1-11-n so as to check the presence of the keyboard display device operated normally and it is transmitted to a rewrite control section 16. Thus, the control section 16 searches a discrimination table 13 to detect that the device 10-1 is usable. Then a device #1 is set to the rewrite register 15 and outputted.

A 5VP2 is connected to this data processing device for performing operations such as loading an initial program and collecting logging information when a failure occurs in the data processing device. In such a data processing device, a specific keyboard display device is allocated for 5vp2, and IPL control is performed or logging information is collected from the keyboard display device allocated as the SVP display device. As this SVP display device, the keyboard display device 10-0 with the lowest machine number #0 is normally assigned.

By the way, such a specific keyboard display device can be used as SvP.
If it is allocated as a display device, this svp
If the display device is in an inoperable state due to a failure, it cannot be used, making it impossible for the data processing device to operate as a system. Therefore, in such cases, a custom engineer had to be called in to repair the SvP display device.

[Purpose of the invention]

An object of the present invention is to improve the problem that when an SvP display device is specified as described above, the system cannot operate if there is a failure in that SvP display device. Check the keyboard display device that can logically operate as a display device, and even if the keyboard display device specified as the SVP display device is in an inoperable state, other operable keyboard display devices can be set as SVP. It is an object of the present invention to provide an sVP display layout control method that enables system operation by allocating a display device as a display device and performing IPL etc. using this device.

[Structure of the invention]

In order to achieve the above objects, the SVP display allocation control method of the present invention includes a service processor and a plurality of keyboard display devices, and a specific one of the plurality of keyboard display devices is used as a display for this service processor. In a data processing device configured to be used as a service processor, a determination table containing data for determining whether or not one of a plurality of keyboard display devices can be used as a display device for a service processor, and the plurality of keyboard display devices Normally used The present invention is characterized in that, if the keyboard display device being used is abnormal, another keyboard display device is selected from the determination table and used as the display device for the service processor.

[Embodiments of the invention]

An embodiment of the present invention will be described based on FIGS. 2 and 3 and with reference to FIG. 1.

FIG. 2 is a block diagram of one embodiment of the present invention, most of which is provided in the host processor, and FIG. 3 is an explanatory diagram of its operation.

In the figure, parts with the same reference numerals as others indicate the same parts. Reference numeral 11 denotes an operating state indicating section, which includes a keyboard display device 10-0.10-.
1----10- Division 11-0 corresponding to each n, ti
-i-...11-n, and 12 is a normality determination unit that determines whether the keyboard display device specified in advance as a display device for the service processor can operate normally. Things to do, 1
3 is a determination table in which data indicating whether or not the keyboard display device can be used as a service processor display device is entered; 14 is a service processor display device entry register which is used in advance as a service processor display device; 15 is a rewriting register in which the machine number of the specified keyboard display device is entered prior to IPL, and when the display device entered in the service processor display device entry register 14 cannot operate normally, the service processor is used instead. The machine number of the keyboard display device used as a processor display device is entered, 16 is a rewriting control unit, 17 is an inverter, 18.1
9 is an AND circuit, and 20 is an OR circuit.

The operating state instruction section 11 includes a keyboard display device 10-0.
This is to display whether or not 10-1...-10-n is operating normally, and is classified into 11 corresponding to each keyboard display device.
-0.11-1, -1, and 11-n are set, and for example, "1" is written in the normal state, and "0" is written in the inoperable state.

This operating state is entered on each keyboard display device'0-0.
It is configured to be performed when the 10-1-40-n is powered on, that is, when the power is turned on.

The judgment table 13 indicates whether the keyboard display device can be logically used as a service processor display device. For example, if it is usable, it is accepted, and if it is not usable, it is rejected, depending on the machine number. It is to be displayed. In this case, if the condition for using it as a service processor display device is, for example, Japanese display, instead of just writing whether it can be logically used as a service processor device or not, each keyboard display device should be used as a service processor display device. It may also be possible to enter the characteristics of the service processor display device and search for each of these characteristics to select a service processor display device that meets the necessary conditions.

When the keyboard display device specified as a service processor display device is inoperable, the rewriting control unit 16 accesses the determination table 13 and extracts a keyboard display device that can be used as a service processor display device from among other keyboard display devices. This is then entered in the rewriting register 15.

Next, the operation of the present invention will be explained based on FIG. In this case, the keyboard display device 110-0 shown as machine number #0 in FIG. 2 is specified as a service processor display device (hereinafter referred to as console). Therefore, machine number #0 is written in the service processor display device entry register 14 in FIG.

■If you turn on the data processing device now, first the machine number #0 will be written in the number-bisprocessor display device entry register 14, and the keyboard display device 10-0.10-1/-4.
0-n correspond to the corresponding classifications 11-0 of the operating state indicating unit 11 depending on whether the operation is normal or inoperable.
．． For example, if the operation is normal for 11-1 and -11-n,
”, and if the operation is impossible, set it to “0”. The contents of this operating state indicating section 11 are checked by the normality determining section 12, and thereby each keyboard display device 1O-O1I
The operating status of Q-1-IQ-n can be checked.

■In this case, when the keyboard display device 10-0 used as a console operates normally, that is, when the console is in an operable state, "1" is set in the category 11-0, so the normality determination unit 12 is set to "1". Since the AND circuit 18 is turned on and the AND circuit 19 is turned off due to the presence of the inverter 7, the machine number #0 written in the service processor display device entry register 14 turns on the AND circuit 18 and the OR circuit 20. is output via
This becomes the console display signal. In this way, the host processor recognizes the keyboard display device 10-0 as a console, and it becomes possible to perform, for example, IPL control from the keyboard display device 10-0.

■However, if the keyboard display device 10-0 is inoperable for some reason, as shown in FIG.
1-0 is set to "0", so when the normality determination unit 12 detects that this division 11-0 is "0",
It outputs "0" and turns off the AND circuit 18. At this time, the inverter 17 outputs "1" and the AND circuit 19
is in the on state.

■ At this time, the normality determination unit 12 determines whether the other categories 11-1 to 11
-n, and checks whether there is a keyboard display device that is operating normally, and if the classification of the keyboard display device used as a console is set to "0" and other keyboard display devices are operating normally. If there are any, these information is transmitted to the rewrite control unit 16. As a result, the rewrite control unit 16 reads the determination table 13 and searches for a keyboard display device that can be used as a console. Then, for example, it is detected that the keyboard display device 10-1 of machine number #1 can be used as a console.

■At this time, the normality determination unit 12 gives “1” to the category 11-1;
r I J in section 11-2, - "0" in section 11-n
” is set, the rewrite control unit 16 determines that the keyboard display device with machine number #1 can be used as a console, and the rewrite register 15 is thereby set. Number #1 is set.

■At this time, the AND circuit 19 receives “1” from the inverter 17.
is transmitted and is in the on state, so the machine number #1 set in the rewriting register 15 is outputted via the AND circuit 19 and the OR circuit 20.

As a result, the host processor 1 recognizes the keyboard display device 10-1 as a console in this case, thereby allowing the system to operate, and performs IPL and logging control from the keyboard display device 10-1.

(2) If the failure of the keyboard display device 10-0, which was inoperable in (2) above, is repaired and the keyboard display device 10-0 is restored to normal operation, "1" will be set in the section 11-0. In response to this, the normality determination unit 12 outputs "1" to the AND circuit 8, turning the AND circuit 18 on, and conversely, the inverter 17 outputs "0", turning the AND circuit 19 off. Therefore, the machine number #0 set in the service processor display device entry register 14 is again output as a console display signal. In this way, the keyboard display device 10-0 whose malfunction has been repaired takes over the status of the keyboard display device 10-1 of machine number #1 and is used as a console again. -1 is released as a console and can be used for other purposes.

〔Effect of the invention〕

According to the present invention, even if a failure occurs in the keyboard display device used as a console, the data processing device can be operated using another keyboard display device, so data processing efficiency can be improved. .
