    摘要： A server system has servers that can be operated through switching as a primary system and a standby system, and a shared disk unit for storing data accessed by the servers. Each of the servers has a driver that acquires information on a configuration inside the shared disk unit after starting of the system. The driver sets the shared disk unit in an active state in which an access request can be sent to the shared disk unit. Access control determines whether the access request issued by an application should be sent on the basis of a management table indicating inhibited types of access requests for each access destination. The access control sends the access request to the driver when the access request is not inhibited for an access destination of the access request. By this arrangement, hot standby switching processing can be performed at high speed.

    摘要： An enqueue structure type is provided within a coupling facility to record the use state and to manage a request queue of resources shared among programs on computers of a system. All programs to use a shared resource issue a request to reserve the shared resource to the coupling facility before using it. The coupling facility affords the permission to use the resource to the programs if it is usable, and adds the programs to the resource request queue if unusable. When a program using the shared resource frees it, the coupling facility fetches a program from the beginning of the request queue, reserves the shared resource for the next program and notifies the next program that the use of the shared resource has been approved. On receiving the notification, the program uses the shared resource without asking the coupling facility for the approval of the use of the shared resource again. Further, exclusive control of shared resources by use of a spin lock having shared and exclusive attributes is implemented by using two locks for one shared resource, wherein the first lock is reserved and then freed after the second lock is reserved.

    摘要： A remote copy system includes a plurality of storage systems. Each first storage system assigns a sequential number to write data received from the host and sends the write data with the sequential number to the second storage system. One of the first storage systems defers the processing of the write request received from the host and instructs each of the first storage systems to create a marker that includes a sequential number that is a marker number. The second storage systems receive the marker from the first storage system and store the marker number included in the marker.

    摘要： A storage system maintains consistency of the stored contents between volumes even when a plurality of remote copying operations are executed asynchronously. A plurality of primary storage control devices and a plurality of secondary storage control devices are connected by a plurality of paths, and remote copying is performed asynchronously between respective first volumes and second volumes. Write data transferred from the primary storage control device to the secondary storage control device is held in a write data storage portion. Update order information, including write times and sequential numbers, is managed by update order information management portions. An update control portion collects update order information from each update order information management portion, determines the time at which update of each second volume is possible, and notifies each-update portion. By this means, the stored contents of each second volume can be updated up to the time at which update is possible.

    摘要： Provided are a method, system, and article of manufacture for controlling a first storage system receiving commands from a first and second managers to create a consistency group with a second storage system. Host writes are received at the first storage system, wherein the first storage system includes a first storage system primary site and a first storage system secondary site. The first storage system sends the host writes from the first storage system primary site to the first storage system secondary site. Host write operations are quiesced at the first storage system in response to a first command from a first manager. Host write operations are resumed at the first storage system in response to receiving a second command from the first manager. The first storage system receives a run command with a marker, wherein the marker indicates a cycle number to control the cycles of the first and second storage systems. The first storage system sends the marker from the first storage system primary site to the first storage system secondary site. The first storage system sends the marker to a second manager. The first storage system applies the host writes to the first storage system secondary site. The first storage system sends a first message to the first storage system primary site from the first storage system secondary site after completing the applying of the host writes. The first storage system sends a second message to the first manager indicating whether conformation was received from the first storage system secondary site that the host writes were applied.

    摘要： Provided are a method, system, and article of manufacture for managing consistency groups using heterogeneous replication engines replicating data. A common linkage manager issues a prepare to create consistency group command to a first replication manager and a second replication manager, wherein the first and second replication managers issue create consistency group commands to first and second replication engines, respectively, to form a consistency group of data at a first source storage and a second source storage to copy to a first target storage and second target storage, respectively. The first and second replication managers form a first consistency group and a second consistency group of data from the first and second source storages, respectively, that are consistent as of a point-in-time in response to the create consistency group command; transmitting, by the first and second replication managers, the data in the formed first and second consistency groups to a first journal and second journal, respectively. The first and second replication managers commit the data in the first and second consistency groups in the first and second journals to the first and second target storages, respectively, in response to the first and second replication managers receiving a commit command.

    摘要： First and second storage apparatuses respectively and internally set a remote copy pair for copying data of a first volume to a second volume and associate a third volume with a remote copy pair according to an external command. When an I/O request to the first volume ends in an error, a host computer sends an I/O request directed to the second volume to the second storage apparatus. If the first and the second storage apparatuses detect a failure in the first or the second storage apparatus of the other side or a connection failure between the first and the second storage apparatuses, the first and the second storage apparatuses store in the third volume a failure information flag showing that the failure was detected.
