摘要： A method, system, and computer program product to preserve data integrity in a mirror and copy environment is disclosed herein. In one embodiment, a method may include receiving a write command and data from a host device. The method may further include writing the data to a primary storage device and attaching a primary sequence number associated with the primary storage device to the write command, thereby providing a numbered write command with a command sequence number. The numbered write command may then be transmitted to a secondary storage device. The method may further include comparing the command sequence number to a secondary sequence number associated with the secondary storage device. If the command sequence number matches the secondary sequence number, then the command may be executed. Otherwise, it may be ignored.
摘要翻译：本文公开了一种在镜像和复制环境中保护数据完整性的方法，系统和计算机程序产品。在一个实施例中，一种方法可以包括从主机设备接收写命令和数据。该方法还可以包括将数据写入主存储设备并将与主存储设备相关联的主序列号附加到写命令，从而提供具有命令序列号的编号写命令。然后可以将编号的写入命令发送到辅助存储设备。该方法还可以包括将命令序列号与与辅助存储设备相关联的次序列号进行比较。如果命令序列号与二次序列号匹配，则可以执行该命令。否则可能会被忽略。

摘要： Provided are a system and program for managing operation requests using different resources. In one embodiment, a first queue is provided for operations which utilize a first resource of a first and second resource. A second queue is provided for operations which utilize the second resource. An operation is queued on the first queue until the first resource is acquired. The first resource is released if the second resource is not also acquired. The operation is queued on the second queue when the first resource is acquired but the second resource is not. In addition, the first resource is released until the operation acquires both the first resource and the second resource.
摘要翻译：提供了一种用于使用不同资源来管理操作请求的系统和程序。在一个实施例中，为使用第一和第二资源的第一资源的操作提供第一队列。为使用第二资源的操作提供第二队列。操作在第一个队列中排队，直到获取第一个资源。如果没有获得第二个资源，则第一个资源被释放。当获取第一个资源但第二个资源没有时，操作在第二个队列中排队。此外，第一资源被释放，直到操作获取第一资源和第二资源。

摘要： A data transfer application implemented in a computational device receives a request to copy a plurality of storage volumes that form a consistency group. A determination is made that a first storage volume of the plurality of storage volumes is more likely to be written into than a second storage volume of the plurality of storage volumes, in response to receiving the request to copy the plurality of storage volumes. The first storage volume is copied before copying the second storage volume, in response to determining that the first storage volume is more likely to be written into than the second storage volume.

摘要： An apparatus, system, and method are provided for maintaining task prioritization and load balancing of I/O tasks on servers coupled by a plurality of communication channels. The apparatus includes a task controller for maintaining system resources on a failed target channel while resubmitting an unsuccessful task to a different channel. Also, the apparatus includes an upgrade module for upgrading a task prioritization level of a failed I/O task. Additionally, a load module is provided for balancing I/O tasks evenly across the plurality of communication channels according to a prioritization algorithm. The system includes the task controller and a device controller configured to interface with the task controller. The method includes a computer readable medium with computer readable code for selecting a channel, upgrading the prioritization level of a failed task, and maintaining resources on the failed channel while resubmitting the failed I/O task on a different channel.

摘要： Provided is a method, system and program for synchronizing sequential subtasks of a task, so that the subtasks can be dispatched to generate operations in a particular sequence. In one embodiment, a subtask which has been prepared for dispatching is queued in a queue until the queued subtask is the next subtask in sequence for dispatching. In one embodiment, the subtasks may be sorted in the queue by task and by subtask sequence.
