摘要： A method and apparatus for enabling an on-line reconfiguration of striped data in a disk array storage device. A replicated copy of the striped logical device is made in parallel with host operations. A logical device with a new configuration is then substituted for access by the host application even before any data is transferred to locations within the newly configured logical device. Independent processes operating in this disk array storage device reconfigure the data transparently to any host operations while accommodating host I/O requests directed to locations in the new configuration.

摘要： A system and method for initializing large portions, or extents, of a mass-storage device in the background so that such overwriting processes do not significantly affect latency as experienced by a host. The method extends the use a system intended for background copying of data from a source extent to a destination extent to that of initializing an extent on a mass-storage device. It does so by causing the system to treat the defined extent as both a source extent and as a destination extent simultaneously.

摘要： Disk array storage device apparatus 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： A method and apparatus for enabling a magnetic disk storage device that stores data according to a first data structure characterized by a fixed-length disk block size to respond to input/output requests from a host that define data according to a different data structure characterized by a different fixed-length host block size. A host adapter transfers requests and data between the host and a cache memory in the magnetic disk storage device as host blocks. A disk adapter transfers requests and data between the cache memory and magnetic disks as disk blocks. CRC data and a sector number are appended to each host block in a set of disk blocks.

摘要： A method and apparatus for verifying the organization of a magnetic disk storage system in which individual storage logical volumes are grouped in sequence as components of a meta device. Data concerning the organization of the meta device is stored in each storage logical volume in a dedicated storage area and in a global memory accessible to the data processing system. Whenever the integrity of the meta device is tested, the data in the configuration file and the data in the dedicated storage area are analyzed and compared. If identity exists, integrity is assumed. If identity does not exist various errors are generated to prevent use of the storage logical volume until the problem is resolved.

摘要： A method, computer program product, and computing system for receiving a Mode Select command concerning a logical unit number (LUN) from a first host, wherein the Mode Select command defines control information and host identifier information concerning the first host, and the LUN is currently being controlled by a second host. The Mode Select command is processed to determine if the control information and host identifier information included within the Mode Select command signifies an intent by the first host to seize control of the LUN from the second host. If the control information and host identifier information signifies an intent to seize control of the LUN from the second host, the control information and host identifier information included within the Mode Select command is written to a buffer associated with the LUN, wherein the buffer includes a control field and a globally unique identifier (GUID) field.

摘要： A method, computer program product, and computing system for receiving a Mode Select command concerning a single LUN from each of a plurality of potential hosts. Each Mode Select command defines control information and host identifier information concerning the potential host associated with the Mode Select command. The received Mode Select commands are processed serially and in accordance with the order in which the Mode Select commands were received. The first Mode Select command received is accepted and subsequent Mode Select commands received are rejected, thus defining an accepted Mode Select command and one or more rejected Mode Select commands. The control information and host identifier information included within the accepted Mode Select command are written to a buffer associated with the single LUN. The buffer includes a control field and a GUID field.
