摘要： Methods, apparatus and computer program products implement embodiments of the present invention that include identifying, by a first computer, multiple network paths to a second computer, and splitting an input/output (I/O) request for a logical volume stored on the second computer into sub-requests. A probe request defining an association between the I/O request and the sub-requests is conveyed to the second computer, and each of the sub-requests is assigned to a respective one of the multiple network paths. Each of the sub-requests are conveyed to the second computer via the assigned respective one of the multiple network paths, and the sub-requests are received by the second computer via the multiple network paths. The second computer performs the sub-requests in response to the association, and a result of each of the sub-requests is conveyed to the first computer via the assigned respective one of the multiple network paths.

摘要： Methods, apparatus and computer program products implement embodiments of the present invention that include configuring, by a source storage system, a logical volume to comprise source regions of the source storage system that have a mapping between a host computer and the source storage system, the source regions storing source data. The source data is copied from the source regions to target data in target regions of a target storage system, the target regions being in a one-to-one correspondence with the source regions, and the volume is reconfigured so that the target regions have the mapping between the host computer and the source storage system. In some embodiments, the mapping between the host computer and the source storage system comprises a first mapping, and upon reconfiguring the volume, a second mapping can be added between the host computer and the target storage system, and the first mapping can be deleted.

摘要： Methods, apparatus and computer program products implement embodiments of the present invention that include detecting, by a storage system, a change in a mapping of a logical volume to one or more host ports of a host computer communicating with the storage system via a storage area network (SAN). Subsequent to detecting the change, first and second input/output (I/O) requests for the logical volume are received from a given host port, and a first unit attention message is conveyed to the given host port in response to the first I/O request. A second unit attention message is conveyed to the given host port upon determining that the storage system received the second I/O request within a specific time period commencing upon receiving the first I/O request. However, the second I/O request can be performed if the storage system received the second I/O request subsequent to the specific time period.

摘要： Methods, apparatus and computer program products implement embodiments of the present invention that include a storage device configured to store a logical volume mapped between a host computer and a computer having multiple initiator ports, and a processor configured to detect a unit attention condition for the logical volume. Examples of unit attention conditions for the logical volume include management operations on the logical volume and host requests for the logical volume. Upon determining, based on the unique serial number, that the processor has previously conveyed the unit attention code to any of the multiple initiator ports, to reconvey an input/output (I/O) request, receive a response for the I/O request, and convey the result to the host computer.
