摘要： Methods and systems for preserving a disk geometry when relabeling a storage device containing data migrated from a previous data storage device having different disk geometry. Prior to relabeling, the label of the storage device includes information on the disk geometry of the previous data storage device. An exemplary method includes reading the label of the storage device in response to a request for information related to a disk geometry of the storage device, which is normally answered without reference to the label of the storage device, and reporting the information related to the disk geometry from the label if the label is associated with an operating system that considers a geometry of a storage device when partitioning.

摘要： A method for enhancing the performance of an application on a data processing system that operates with a disk array storage device in which the completion of tasks associated with different transactions with one logical storage device are conditions precedent to the completion of other transactions. Specific tasks related to the one logical device are given priority over tasks related to all other logical storage devices. In a specific implementation reconnect tasks are given the highest priority with reconnect tasks from the one logical storage device being given the highest priority. A second category of tasks related to the one logical storage device can be given priority over all other tasks except reconnect tasks. All other tasks are given a priority below that of the first and second task categories.

摘要： This invention is a data storage system that includes logic configured for carrying out a method to allow a so-called “re-labeling” of a logical volume. Re-labeling changes the label configuration originally put in place by the host at a first device and replicated to a second device. The re-labeling takes place during a certain operation that takes the second device offline to a host computer in communication with the data storage system. This re-labeling avoids labeling conflicts that could arise when duplicate labels result on two different devices as a result of the replication.
