摘要： Provided is a method of managing a computer system including a plurality of storage systems and a plurality of management appliances for managing the plurality of storage systems. A first management appliance and a second management appliance hold an identifier of a first storage system and management data obtained from the first storage system. The method includes the steps of: selecting a third management appliance from the plurality of management appliances when a failure occurs in the first management appliance; transmitting the identifier held in the second management appliance from the second management appliance to the selected third management appliance; and holding the identifier transmitted from the second management appliance in the selected third management appliance. Thus, it is possible to prevent, after failing-over due to an abnormality of a maintenance/management appliance, a single point of failure from occurring to reduce reliability of the maintenance/management appliance.

摘要： A technique determines which configuration change(s) caused an application invocation failure of a computer application without the need for a knowledge database. To determine which configuration change is the most likely cause, the cause analysis program (121) checks other computers (102) that have experienced the same configuration changes. The cause analysis program checks and counts the application invocation results before and after each configuration change is done. If the same configuration changes are found in the other computers, the program checks whether each configuration change caused or cured the same problem in that computer. The program counts the similar cases for all of the computers. Subsequently, the program calculates the ratio of those instances involving a change from success to failure and the ratio of those instances involving a change from failure to success out of all instances for each configuration change.

摘要： A root cause analysis engine uses event durations and gradual deletion of events to improve analysis accuracy and reduce the number of required calculations. Matching ratios of relevant rules are recalculated every time notification of an event is received. The calculation results are held in a rule memory in the analysis engine. Each event has a valid duration, and when the duration has expired, that event is deleted from the rule memory. Events held in the rule memory can be deleted without affecting other events held in the rule memory. The analysis engine can then re-calculate the matching ratio of each rule by only performing the re-calculation with respect to affected rules related to the deleted event. The calculation cost can be reduced because analysis engine processes events incrementally or decrementally. Analysis engine can determine the most possible conclusion even if one or more condition elements were not true.
摘要翻译：根本原因分析引擎使用事件持续时间和逐渐删除事件，以提高分析准确性并减少所需计算的数量。每次收到事件通知时，都会重新计算相关规则的匹配比例。计算结果保存在分析引擎的规则存储器中。每个事件都有有效的持续时间，当持续时间到期时，该事件将从规则存储器中删除。在规则存储器中保存的事件可以被删除，而不会影响规则存储器中保存的其他事件。然后，分析引擎可以通过仅针对与已删除事件相关的受影响规则执行重新计算来重新计算每个规则的匹配比例。计算成本可以减少，因为分析引擎会逐渐或者递减地处理事件。分析引擎可以确定最可能的结论，即使一个或多个条件元素不是真的。

摘要： In order to store data in disk drives securely in an environment with a mixture of disk drives having write protection mechanisms and disk drives without write protection mechanisms, a different write protection mechanism must be checked for each of the disk drives, and write protection must be defined for each of the disk drives storing data to be saved, which may impose a large load on system administrators. There is provided a storage controller for performing data input/output processing from a computer by managing volumes of multiple storage subsystems as external volumes and by using these external volumes as virtual volumes. In the data input/output processing, write protection is achieved based on an access attribute set for each of the virtual volumes. When an access attribute is set for a virtual volume, the same access attribute is set for an external volume corresponding to the virtual volume. Thus, the write protection is achieved for the external volume corresponding to the virtual volume.
摘要翻译：为了将磁盘驱动器中的数据安全地存储在具有写保护机制的磁盘驱动器和没有写保护机制的磁盘驱动器的环境中，必须为每个磁盘驱动器检查不同的写保护机制，写保护必须为存储要保存的数据的每个磁盘驱动器定义，这可能对系统管理员施加大量负载。提供了一种存储控制器，用于通过将多个存储子系统的卷作为外部卷并通过将这些外部卷用作虚拟卷来从计算机执行数据输入/输出处理。在数据输入/输出处理中，基于为每个虚拟卷设置的访问属性来实现写入保护。当为虚拟卷设置访问属性时，将为与虚拟卷对应的外部卷设置相同的访问属性。因此，对于与虚拟卷对应的外部卷实现写保护。

摘要： When an active data copy process relative to a logical storage device is performed without involving a computer, an access permission/rejection of the computer to the logical storage device is checked by referring to a correspondence between WWN of the computer and a logical storage device identifier LUN to thereby determine whether an access to a copy source logical storage device and a copy destination logical storage device is permitted or not. It is therefore possible to prevent an outflow of illegal data from a storage subsystem to be caused by an active copy instruction command.
摘要翻译：当在不涉及计算机的情况下执行相对于逻辑存储设备的活动数据复制处理时，通过参考计算机的WWN与逻辑存储设备标识符之间的对应关系来检查计算机对逻辑存储设备的访问允许/拒绝 LUN，从而确定是否允许对复制源逻辑存储设备和复制目的地逻辑存储设备的访问。因此，可以防止来自存储子系统的非法数据的流出由主动复制指令命令引起。

摘要： In a high frequency power amplifier module of a multi-stage structure in which a plurality of heterojunction bipolar transistors (npn-type HBTs) are cascade-connected, a protection circuit in which a plurality of pn junction diodes are connected in series is connected between the collector and emitter of each HBT. The p-side is connected to the collector side, and the n-side is connected to the emitter side. A protection circuit in which pn junction diodes of the number equal to or smaller than that of the pn junction diodes are connected in series is connected between the base and the emitter. The p-side is connected to the base side, and the n-side is connected to the emitter side. With the configuration, in the case where an overvoltage is applied across the collector and emitter due to a fluctuation in load on the antenna side, the collector terminal is clamped by an ON-state voltage of the protection circuits, so that the HBT can be prevented from being destroyed. Since the similar protection circuit is assembled between the base and emitter, even when the operator touches the module at the time of manufacturing the high frequency power amplifier module, the HBT can be prevented from being destroyed by the clamping effect of the protection circuit between the base and emitter and the protection circuit between the collector and emitter. Thus, an improved manufacturing yield of the high frequency power amplifier module and a wireless communication apparatus can be achieved, and destruction caused by fluctuation in load impedance of the wireless communication apparatus can be prevented.
摘要翻译：在其中级联多个异质结双极型晶体管（npn型HBT）的多级结构的高频功率放大器模块中，将多个pn结二极管串联连接的保护电路连接在每个HBT的集电极和发射极。 p侧连接到集电极侧，并且n侧连接到发射极侧。其中pn结二极管的数量等于或小于pn结二极管串联的保护电路连接在基极和发射极之间。 p侧连接到基极侧，并且n侧连接到发射极侧。通过该结构，由于天线侧的负载的波动，在集电极和发射极两端施加过电压的情况下，集电端子被保护电路的导通状态电压钳位，HBT可以防止被摧毁。由于类似的保护电路组装在基极和发射极之间，即使在制造高频功率放大器模块时操作者接触模块时，也可以防止HBT被保护电路的钳位效应所破坏基极和发射极以及集电极和发射极之间的保护电路。因此，可以实现高频功率放大器模块和无线通信装置的制造成品率的提高，并且可以防止由无线通信装置的负载阻抗的波动引起的破坏。

摘要： Data states of storage apparatuses are managed. When a storage apparatus is allocated from a storage pool to a computer, management information written in the storage apparatus is erased if the data state of the storage apparatus is unknown. When the storage apparatus becomes unnecessary and is restored to the storage pool, the management information is also erased. Further, when the storage apparatus is allocated to the computer, a level of confidentiality is set. When the storage apparatus is restored to the storage pool, data in the storage apparatus is automatically erased according to the set level of confidentiality.
