摘要:
A storage system is disclosed comprising a management computer and multiple storage subsystems with multiple volumes accessible to a host computer. The host computer sends volume configuration information to the management computer. Each storage subsystem retrieves information from the volume directory corresponding to a requested volume and sends it to the management computer. The management computer comprises a volume information table holding the volume configuration information obtained from the host computer, information on storage subsystems, and use-related ID group IDs; a unit which identifies the volumes belonging to a specified group ID, locates the storage subsystems these volumes belong to, and obtains information on the desired volumes from their corresponding volume directories; and a display device which displays information on the usage of the volumes that is obtained from storage subsystems. Thus, volume information in multiple storage subsystems can be collected in an integrated manner, thereby reducing management overhead.

Dump information acquiring and system recovery methods for a computer system using a virtual memory. The computer system has a plurality of external storage units normally used as a paging device unit for holding the contents of the virtual memory to be paged out. When fault occurs, a program for acquiring dump information outputs the contents of the main storage to a dump file. The identifier of the external storage unit set to definition information defining the external storage unit is changed from the identifier of the external storage unit to the identifier of another external storage unit. Thereafter, the computer system is restarted. The contents of the virtual memory held in the paging device unit at the time of fault output to the dump file.

According to the present invention, even when any one of the computers constituting a computer system becomes inoperable, a series of flow of distributed processing can be traced. Application program 120 in computer 100A requests computer 100B to perform a part of the series of the processes (S106). Log information items in the computer 100A, to which an ID issued to a series of processes is attached, are transmitted to the computer 100B by the log transmission program 152 in the computer 100A (S110). The log information receiving program 153 of the computer 100B receives these log information items and stores them in logbuffer 160 (S221, S222). The application program 120 in the computer 100B executes thus requested processing, and returns the process result to the computer 100A (S206). The log information items of the computer 100B each having the above ID, generated by executing the processing, are transmitted to the computer 100A by the log transmission program 152 of the computer 100B (S210) , and the log information receiving program 153 of the computer 100A receives this log information items and stores them in the log buffer 160 (S121, S222).
摘要:
A dump information acquiring method and a system recovery method for a computer system using a virtual memory, the methods being used when fault occurs in the computer system. The computer system has a plurality of external storage units used as a paging device unit for holding the contents of the virtual memory to be paged out from a main memory. During the normal operation, an external storage unit selected from the plurality of external storage units is used as the paging device unit. When fault occurs, a program for acquiring dump information operates to output the contents of the main storage at the time of the fault occurrence to a dump file. The identifier of the external storage unit set to definition information for defining the external storage unit used as the paging device unit is changed from the identifier of the external storage unit used as the page device unit to the identifier of another external storage unit. Thereafter, the computer system is restarted. The contents of the virtual memory held in the paging device unit at the time of the fault occurrence are output to the dump file by a program executed in a background of a job process of the current computer system or by a program executed by another computer system.
摘要:
According to the present invention, as regards a computer system that uses virtual storage management, because content of auxiliary storage utilized by paging is used, dump information can be obtained by outputting only a part of the content of the auxiliary storage at the time of occurrence of an abnormal system condition. As a result, time required to restart the computer system and business can be shortened. What is more, because it is not necessary to add a special external storage for obtaining dump information, computer resources can be utilized more efficiently.

A vehicle air conditioner includes an air-conditioning ECU. The air-conditioning ECU performs a cooling mode operation in which air is cooled by an interior heat exchanger in a cooling refrigeration cycle. The air-conditioning ECU performs a heating mode operation, in which air is heated by the interior heat exchanger in a hot gas heater cycle. The air-conditioning ECU performs an air blowing operation in which air is blown toward an inner surface of a windshield of the vehicle without operating the compressor before performing a refrigerant collecting operation.

A synchronization device for a manual transmission of a vehicle, including a synchronizer ring configured to synchronize rotation of a transmission gear and clutch hub. The synchronizer ring includes: a ring body having an annular shape; an axial protruding portion protruding from the ring body toward the clutch hub in an axial direction to set a size of an axial clearance between the ring body and the clutch hub; and a radial protruding portion protruding from the ring body toward the clutch hub in a radial direction intersecting the axial direction to set a size of a radial clearance to be formed between the ring body and the clutch hub. The ring body, the axial protruding portion, and the radial protruding portion are formed integrally by metal stamping.

A restricting pin is provided so as to be slidable in a moving direction of a front end of a reverse restricting member provided at a select lever for selecting forward and reverse fork shafts switching a shift gear(s), and is biased toward the reverse restricting member. A lockout lever that can be inserted into/detached from between the restricting pin and the front end of the reverse restricting member is biased toward an insertion side by a spring, and at a vehicle speed less than a predetermined vehicle speed. A front end of an advancing operating rod of the actuator contacts and is detached against the force of the spring. At a vehicle speed not less than a predetermined vehicle speed, the front end of the reverse restricting member contacts the inserted lockout lever, thereby preventing the select lever from moving to a reverse select position.
