  • Patent number: 10013188
    Abstract: A determining unit determines, when a failover occurs, whether the storage device is a master device. If the determining unit determines that the storage device is not the master device, a converting unit converts the virtual LUNs of the copy source and the copy destination to the real LUNs. Then, a copying unit performs a copy process by using the real LUNs converted by the converting unit.

  • Patent number: 9841923
    Abstract: While in active state, a first storage apparatus including first and second storage areas copies data stored in the first storage area to the second storage area, copies data stored in the first storage area to a third storage area so that data is synchronized between the first and third storage areas, and copies data stored in the second storage area to a fourth storage area so that data is synchronized between the second and fourth storage areas. When a second storage apparatus including the third and fourth storage areas has transitioned from standby to active state and thereby gets to receive access to the third storage area, instead of to the first storage area, from an external information processing apparatus, the second storage apparatus copies data stored in the third storage area to the fourth storage area, based on setting information stored in a storage unit.

  • Patent number: 9594526
    Abstract: When a failure occurs in a storage device, a backup unit specifies LUNs of a copy source and a copy destination to an operation volume for which a process is not taken over to another storage device and instructs to perform a copy. When a copy processing unit in the storage device receives a copy process to be performed in the operation volume, the copy processing unit performs the copy process by using the specified LUNs of the copy source and the copy destination. If an error occurs without the copy process being taken over to another storage device due to the occurrence of a failover, the backup unit acquires the LUNs of two volumes of a copy pair and the volumes each constituting each of cluster pairs. Then, the backup unit again performs the copy process by using the acquired LUNs.

  • Patent number: 9552265
    Abstract: There is provided an information processing apparatus including a control unit. The control unit adds type information indicating a first type in a first operation request in which operation target storage devices are specified by unique identifiers, respectively, used in a first storage apparatus and outputs the first operation request to the first storage apparatus through the network. When the control unit transmits the first operation request to a second storage apparatus and receives an error response indicating a type error from the second storage apparatus after transparent failover is executed, the control unit adds type information indicating the second type in a second operation request in which operation target storage devices are specified by unique identifiers, respectively, used in the second storage apparatus and outputs the second operation request to the second storage apparatus through the network.

  • Patent number: 8938596
    Abstract: In a storage apparatus, when a received backup instruction is a backup start instruction, a control unit performs a backup process from a position indicated by an available area start pointer. When the received backup instruction is a backup end instruction, the control unit releases an allocated backup area. In addition, the control unit determines whether the released backup area is adjacent to a position indicated by an available area end pointer. If determining that the released backup are is adjacent to the position indicated by the available area end pointer, the control unit moves the available area end pointer indicating the end of an available area to the end of the released backup area.

  • Patent number: 8725442
    Abstract: The present invention provides a novel measurement method for system parameters of a 5-port junction used in a VNA (Vector Network Analyzer). A VNA is a device for measuring amplitude ratios and phase differences (S-parameters: scattering matrix elements) between incident waves and reflected waves of a DUT (Device Under Test), or between input waves and transmitted waves. What has been newly discovered is that for 5 ports, S-parameters can be expressed by a linear coupling using H and power difference ratios ({P(S)/P(0)}?1). It is possible to easily calculate parameter H using a minimum of three already known standards, and amount of calculation can be reduced compared to conventionally.
