A mirror policy indicating volumes in a first storage system is processed to mirror to volumes in a second storage system and volumes in the second storage system to mirror to volumes in a third storage system. The third storage system is at a first geographical location remote with respect to a second geographical location including the first and second storage systems. A command is transmitted to cause the copying of updates to the volumes in the first storage system to corresponding volumes in the second storage system indicated in the mirror policy. Upon an occurrence of an event, the causing the suspension of the copying of updates to the volumes in the first storage system indicated in the mirroring policy to the volumes in the second storage system.

摘要： Provided are a method, program, and system for managing data. A mirror policy is processed indicating volumes in a first storage system to mirror to volumes in a second storage system and volumes in the second storage system to mirror to volumes in a third storage system, wherein the third storage system is at a first geographical location remote with respect to a second geographical location including the first and second storage systems. A failure is detected of the first and second storage systems at the first geographical location. Automatic reconfiguration is made to network resources directing I/O requests to volumes in the first storage system to direct I/O requests to volumes in the third storage system. A failure of the first storage system and the availability of the second storage system is detected and, in response, network resources are reconfigured to direct I/O requests to volumes in the first storage system to volumes in the second storage system in response to detecting the failure of the first storage system and the availability of the second storage system. Updates to the second storage system are copied to the third storage system after reconfiguring network resources to direct I/O requests to volumes in the first storage system to volumes in the second storage system.

摘要： A continuous availability system including a controller module executing on a computer processor, the system is configured to receive a unit of work and to select a primary site from a plurality of sites to process the unit of work. Once a site is selected the system is further configured to select one of one or more processing systems from the primary site to process the unit of work. The system is additionally configured to replicate the unit of work to at least one other site once the unit of work is completed at the primary site. The system is configured to operate even when the primary site is separated from each of the plurality of sites by a distance greater than a metropolitan area network and the operations occur within a customer acceptability window.

摘要： A primary storage controller is maintained in a copy relationship with a secondary storage controller, wherein the primary and secondary storage controllers are coupled to a host that is configurable to use the secondary storage controller instead of the primary storage controller. The primary storage controller determines occurrence of at least one condition in the primary storage controller, wherein the at least one condition occurs prior to a failure of the host to perform an Input/Output (I/O) operation with respect to at least one storage volume of the primary storage controller. The primary storage controller communicates the occurrence of the at least one condition to the host, wherein in response to the communicating the host is configured to determine whether to use the secondary storage controller instead of the primary storage controller based on the occurrence of the at least one condition.

摘要： Provided are a computer program product and system for maintaining mirror and storage system copies of volumes at multiple remote sites. A first server maintains a mirror copy relationship between a first storage system at a first site and a second storage system at a second site. The first server performs a first point-in-time copy operation from the first storage system to a first storage system copy, wherein the data for the first storage system copy is consistent as of the determined point-in-time. The first server transmits a command to a second server to create a point-in-time copy of the second storage system. The second server processes mirror data transferred from the first server as part of the mirror copy relationship to determine when to create a second point-in-time copy. The second server performs the second point-in-time copy operation.
