摘要： A system and method related to maintaining consistency of replicated data in a data storage environment. The system handles Input/Output (IO)-Requests in a data storage environment having a server and production data stored on a data storage volume on a data storage system. A copy of the production data is stored on another data storage volume of a second data storage system, wherein IO-Requests to update production data are handled so that the data copy is consistent with the production data after processing the IO-Request.

摘要： Methods, systems, and computer program products for postponing bitmap transfers and eliminating configuration information transfers during trespass operations in a disk array environment are disclosed. According to one method, a clone group is stored on a disk array, the clone group including a logical unit (LUN) representing a storage partition on the disk array and a clone of the LUN, the clone being a copy of the data referenced by the LUN. The clone group is associated with a first storage processor (SP) for writing data to the disk array. Changes between the LUN and the clone are tracked by maintaining a data structure indicative of the changes in a memory associated with the first SP. The association of the clone group is changed to a second SP for writing data to the disk array without transferring the data structure to memory associated with the second SP.

摘要： Default isolation method assists in correction of a fault in a peer-to-peer communication link between two storage processors. Each processor is associated with a fault indicator which is activated according to the method to guide a technician in replacing the storage processors one at a time to determine the fault with the peer-to-peer communication link. Upon detection of a fault, one of the processors is suspended so that a technician may replace it with a new storage processor. The surviving storage processor detects whether a new storage processor has been replaced. If the peer-to-peer communication link still fails, the surviving processor instructs the peer processor to boot up and then suspends itself. Communications outside of the peer-to-peer communication link can take place between the processors by leaving a message in at least one of the disk drives which is periodically checked by the processors.
摘要翻译：默认隔离方法有助于校正两个存储处理器之间的对等通信链路中的故障。每个处理器与根据用于指导技术人员一次更换存储处理器的方法激活的故障指示符相关联，以确定与对等通信链路的故障。在检测到故障时，其中一个处理器被暂停，使得技术人员可以用新的存储处理器来代替它。幸存的存储处理器检测是否已更换新的存储处理器。如果对等通信链路仍然失败，则幸存的处理器指示对等体处理器启动，然后暂停自身。通过在由处理器周期性地检查的至少一个磁盘驱动器中留下消息，可以在处理器之间进行对等通信链路之外的通信。
