摘要:
In analyzing an elaborate computer system which requires large-scale or numerous event propagation models, a law-of-causality matrix gains size, so that significant amount of storage resources has been used in a management computer. To solve such a problem, the management computer to manage the computer system stores topologies, event propagation models, and causality information including one or more causal relations in the storage resources, determines, when the management computer analyzes or detects an event, whether a causal relation has already been created for the event to be analyzed, and creates the causal relation based on a topology and event propagation models, if not yet.

The management system of the present invention is capable of efficiently discovering each apparatus coupled to a communication network. The management server 1 judges a type of an apparatus coupled to a communication network 5 on the basis of service utilization information T1, which is acquired from a discovered device or acquired from a device (an iSNS server 4, for example) having a name server function for resolving an address from a public name, and on the basis of discovery management information prepared beforehand (S1, S2). The management server 1 acquires a communication protocol in accordance with the type of the apparatus from protocol selection rules T3, and attempts authentication of the apparatus by using the communication protocol (S3).

To provide a fault analysis result classification function capable of reducing the time required to eliminate a fault in a monitoring target apparatus. The fault analysis results (fault cause candidates) obtained during the fault analysis processing are classified for the influence range of each of the fault cause candidates by analyzing which of the other fault cause candidates relate to the fault events of the apparatus abnormal state, which are used as the basis to derive the each of the fault cause candidates. Further, the classification results are displayed on a GUI.

The invention provides a method for computing the appropriate capacity of a journal volume based on the operating patterns of backup and recovery performed by the user, and composing a recovery system that enables recovery to be performed in a short time using journals. The invention provides a computer system comprising a storage system 120 having a volume 124, a managing computer 100 and a host computer 110, wherein the storage system 120 retains a journal of data stored in the volume and a volume replicating the data stored in the volume, and restoring a volume data at any update time point based on the journal and the replicated volume, and upon receiving operation from a user regarding the volume retaining the journal, the managing computer 100 acquires a registration creation demand including a recovery time objective which is the time to be restored and/or a recovery point objective which is the recovery time point and a journal retention period which is the period for retaining the journal, monitors the journal of data stored in the volume, computes the quantity of the journal, and determines the capacity of the volume for retaining the journal.

The computer system includes: a first storage system having devices that are various components for storing data transmitted from a host computer; a second storage system having devices that are various components for storing data transmitted from the first storage system; and a management apparatus that manages the first and second storage systems. The management apparatus includes a storage unit that stores configuration information, performance information and threshold values used for performance management regarding the devices in the first and second storage systems connected to the management apparatus; and a setting section that adopts and sets, when internal management information and data are copied from the first storage system to the second storage system, threshold values assigned to the devices in the first storage system to the devices in the second storage systems.
摘要:
A storage system allocates a data storage area in response to an access request from a first computer if the capacity of a first physical storage device configuring a first logical storage area, provided to the first computer, is equal to or lower than a predetermined threshold. The storage system associates the first logical storage area with another physical storage device, which is different from the first physical storage device associated with a second logical storage area provided to the first computer and a second computer, and allocates a data storage area from the another physical storage device if the capacity of the first physical storage device associated with the first logical storage area exceeds the predetermined threshold.
摘要:
A computer system including a copy source volume and a copy target volume which may be selectably PAIRED or SPLIT. User management information stores: an entry indicating that a first user is permitted to effect a PAIR operation and a PATH operation; and, an entry indicating that a second user is permitted to effect a PATH operation. Operation management information indicates permitted PATH and PAIR operations in relation to each user and a volume's PAIR or SPLIT status, and stores: an entry indicating that the first user is permitted to effect the PAIR operation in which the PAIR status is PAIR, or is SPLIT WITH BACKUP DISABLED; and, an entry indicating that the second user is permitted to effect the PATH operations in which the PAIR status is SPLIT WITH BACKUP ENABLED. PAIR management information stores the PAIR status and the BACKUP ENABLED or DISABLED status.

This invention provides a system including a computer and a storage-subsystem comprising at least either a first storage area for storing data sent from the computer or a second storage area to be associated with the first storage area, for storing replicated data of data stored in the first storage area. This system includes a replication processing status referral unit for referring to a replication processing status of data of the first storage area and the second storage area to be associated, and an output unit for outputting first performance information concerning data I/O stored in the first storage area, and outputting second performance information concerning data I/O stored in the second storage area together with the first performance information when the replicated data is being subject to replication processing from the first storage area to the second storage area as a result of referring to the replication processing status.
