A management system of a storage system specifies a matching rate between an occurred fault and each of one or more registered faults on the basis of fault analysis information which is information indicating, for each fault, a relation between a fault in the storage system and a fault detail including knowledge base information. Each of the one or more registered faults is a fault in which the information is registered in the fault analysis information. The management system displays information related to the registered fault including the specified matching rate with respect to each of the one or more registered faults.

Management system of storage system

A storage system comprises multiple first storage apparatuses, and a controller which provides a first logical volume corresponding to a storage area of the multiple first storage apparatuses to a host computer. The controller partitions a storage area corresponding to the first logical volume into multiple first physical storage areas, manages the partitioned multiple first physical storage areas as physical storage areas of a storage pool, creates a first virtual volume which is provided to the host computer, and associates, from among the multiple first physical storage areas, a physical storage area in which user data is stored, with the first virtual volume.

Storage system and management method therefor

Events which have occurred in storage systems can be managed easily regardless of complexity of a storage configuration. An event notification systemincludes: an event notifying clientfor detecting the occurrence of an event(s) in volumes of a storage system; a management application serverfor storing information about the occurred event as setting/failure information; and an event information aggregation serverfor creating and managing event informationincluding an event keyfor associating the occurred event with the setting/failure information. When the event information aggregation serverin such an event notification systemnotifies an administrator terminalof the event keyand an administrator selects the event key, the management application serverhas the administrator terminaldisplay an event browse screenindicating the relativity of a volume, in which the event occurred, to a volume in which a related event occurred.

Event notification system, event information aggregation server, and event notification method

Multiple types of storage devices which have different performance are appropriately allocated to multiple virtual volumes in accordance with the performance requirements of the respective virtual volumes. In cases where, among virtual volumesfor which response times have been specified, there is a [virtual volume] that has a shortage of pages to which SSDsshould be allocated and that does not satisfy the performance requirement when its Tier boundary value &#x3b2; is adjusted to Tier boundary value &#x3b2;' and, if unallocated pages as the pages to which SSDsshould be allocated do not exist, Tier boundary value &#x3b3; or Tier boundary value &#x3b1; of another virtual volume is adjusted to Tier boundary value &#x3b3;&#x2032; or the Tier boundary value &#x3b1;&#x2032;, and pages to which SSDsare allocated are secured in the virtual volumefor which the Tier boundary value has been adjusted.

Performance management method for virtual volumes

The storage system is provided with a storage apparatus including a storage medium for storing data, and a management apparatus for managing the storage apparatus. The management apparatus includes an apparatus-side known problem information storage unit for storing known problem information as information concerning a problematic operation or a change of state, a maintenance management terminal operation controller for receiving a user's operation or change of state and creating history information according to the operation or change of state, and an apparatus-side known problem information search unit for searching, from the apparatus-side known problem information storage unit, known problem information corresponding to the history information, wherein the maintenance management terminal operation controller inhibits the operation of the searched known problem information.

Storage system and known problem information management method

A storage system having at least two storage apparatuses capable of partitioning an internal resource into logical partitions and managing the logical partitions, and which replicates data written into a primary volume of a primary storage apparatus as the replication source storage apparatus to a secondary volume of a secondary storage apparatus as the replication destination storage apparatus, including: a configuration information sending unit for sending configuration information of the logical partition, to which the primary volume belongs, to the secondary storage apparatus; and a logical partition setting unit for setting the configuration of the logical partition to which the secondary volume belongs based on the configuration information of the logical partition to which the primary volume belongs sent from the configuration information sending unit.

Storage system and management method thereof

An object of the present invention is to prevent data from being tampered with, and to prevent operation mistakes, when sending and receiving data between a management software managing storage devices. Encrypting predetermined information by using a first key managed by a first manager when temporarily keeping the predetermined information in a data holding unit; decrypting the predetermined information encrypted with a second key kept in a storage device managed by a second storage manager when moving the encrypted predetermined information to the second storage manager; and arranging the predetermined information in the second manager based on the decryption result.

Storage system and storage system management method

Proposed are a storage system and its management method having at least two storage apparatuses capable of partitioning an internal resource into logical partitions and managing the logical partitions, and which replicates data written into a primary volume of a primary storage apparatus as the replication source storage apparatus to a secondary volume of a secondary storage apparatus as the replication destination storage apparatus. With this storage system and its management method, configuration information of the logical partition, to which the primary volume belongs, is sent to the secondary storage apparatus, and the configuration of the logical partition to which the secondary volume belongs is set based on the configuration information of the logical partition to which the primary volume belongs.

This invention aims to optimize an entire storage system by equalizing the access counts in appropriate units. When migrating data in pool volumes to equalize the data access counts, which data migration&#x2014;data migration in units of pages or data migration in units of volumes&#x2014;is most appropriate is judged based on the information stored in an access information table storing access information, which is the information about the access counts for the data stored in the disk drives and, based on the judgment, data is migrated in units of pages or volumes so that the data access counts are equalized among groups. The data migration is repeated until the data access counts are equalized among the groups.

Storage system and access count equalization method therefor

Configuration information settings for a storage device are made highly reliable and facilitated. The storage device includes a service processor for setting storage device configuration information, and a terminal device connected to the service processor via a private line to send a command group, received from an operator and related to the storage device configuration information, to the service processor. The service processor also includes a device for determining approval or denial of execution of the command group prior to execution of the command group received from the terminal device.

Storage device and method of setting configuration information of same

A method for performing a system reconfiguration of a storage system includes displaying a configuration window visually showing a configuration of a plurality of components in the storage system within an operation screen. An input area is displayed within the operation screen, the input area being provided for entering one or more components to be reconfigured. A performance window is displayed within the operation screen, the preference window providing bandwidth utilization information of one or more of the components in the storage system. The configuration window, performance window, and the input area are all viewable at the same time without activating another operation screen.

Management method and apparatus for storage apparatus

The time (response time) from the issue of a display request for the display of constructional information to the obtaining of predetermined desirable constructional information and the completion of display is long when a terminal device having (a graphical user interface) to manage and control the operation of a storage system by using a storage managing server is used. To reduce response time, the storage managing server receives a first request issued from a storage managing terminal for executing the processing of the storage managing server, and a second request for executing processing including the communication of constructional information of a storage device between the storage device and the storage managing server. The storage managing server starts processing with respect to the second request before the storage managing server transmits a response to the first request to the storage managing terminal.

Storage managing method and its device

In an exclusive lock management in common to both the In-Band and the Out-of-band, a lock control technique of a storage system capable of removing the factor that may cause the discrepancy in the configuration information in a disk array system is disclosed. In the storage system, a shared memory in a DKC of a storage subsystem has lock management information for uniformly managing the operation authority for the configuration information in the shared memory that is used in common by both the channels of the host terminals and the management client terminals, and a CPU in the DKC gives the operation authority for changing the configuration information to either the host machine or the management client based on the lock management information in the shared memory in response to an access request from the host terminals or the management client terminals.
