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： 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： 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： 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： 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.
