    • Example embodiments of the present invention provide a method, apparatus and computer-program product for application migration validation. In short, example embodiments of the present invention provide a tool to be run by an administrator prior to migration to determine a pre-migration policy. The administrator then performs the migration. After the migration is complete, the administrator runs to tool again to determine a post-migration policy. The tool then validates the post-migration policy. For example, the tool may compare the pre-migration policy and the post-migration police to determine whether there are differences between the pre-migration policy and the post-migration policy. Alternatively, the tool may compare the post-migration policy against a changed policy, different from the pre-migration policy, deliberately implemented by the administrator. The tool may alert on differences between the pre-migration policy and the desired post-migration policy (i.e., a properly migrated pre-migration policy or a new policy different than the pre-migration policy).
    • 本发明的示例实施例提供了一种用于应用迁移验证的方法,装置和计算机程序产品。 简而言之,本发明的示例性实施例提供了在迁移之前由管理员运行以确定迁移前策略的工具。 然后管理员执行迁移。 迁移完成后,管理员再次运行工具来确定迁移后策略。 该工具然后验证迁移后策略。 例如,该工具可以将迁移前政策和移民后警察进行比较,以确定迁移前政策与移植后政策之间是否存在差异。 或者,该工具可以将迁移后策略与管理员故意实施的与迁移前策略不同的已更改策略进行比较。 该工具可以提醒迁移前策略和所需的迁移后策略(即,正确迁移的迁移前策略或不同于迁移前策略的新策略)之间的差异。

    • Providing a multiple protection snapshot copy of a logical device includes creating the snapshot copy of the logical device, where, in response to a write to a section of the logical device, data is copied to a first alternative storage area prior to the write and, following creating the snapshot copy, pointing portions of the snapshot copy to a second alternative storage area having data that is a copy of the logical device, where data corresponding to the snapshot copy is stored in one of: the first alternative storage area and the second alternative storage area. Providing a multiple protection snapshot copy of a logical device may also include, prior to pointing portions of the snapshot copy to the second alternative storage area and after creating the snapshot copy, copying data from the logical device to the second alternative storage area.
    • 提供逻辑设备的多重保护快照副本包括创建逻辑设备的快照副本,其中响应于写入逻辑设备的一部分,在写入之前将数据复制到第一备用存储区域, 在创建快照副本之后,将快照副本的部分指向具有作为逻辑设备的副本的数据的第二替代存储区域,其中对应于快照副本的数据被存储在以下之一中的一个:第一备用存储区域和第二备用存储区域 替代存储区域。 提供逻辑设备的多重保护快照副本还可以包括在将快照副本的部分指向第二替代存储区域之前并且在创建快照副本之后,将数据从逻辑设备复制到第二替代存储区域。
