摘要： Provided is a method, system, and program for configuring an attached storage device through a storage adaptor. The storage adaptor includes an initialization routine to generate initialization data to write to the storage device when adding storage space in the storage device to a system. A request is received to add storage space to the system. A command is transmitted to the storage adaptor capable of inhibiting the storage adaptor from performing the initialization routine. Initialization data is generated for the storage space and transmitted to the storage adaptor to write to the storage space to initialize the storage space.

摘要： A method and system for controlling access to a bus for transferring data in the form of multibyte data streams. Data transfer agents are coupled to and request access to the bus to transfer data thereon. The system for controlling access to the bus comprises a bus arbiter responsive to the access requests of the data transfer agents, granting access to the bus to one data transfer agent at a time. A data length counter accumulates, during the grant of access, signals indicating the length of the data transferred between the bus and the data transfer agent. The data length counter indicates completion of the transfer of a predetermined length of data, and bus arbiter logic responds to the data length counter indicating the transfer completion, causing the bus arbiter to terminate the grant of access to the data transfer agent. The control of access to the bus is thus based on the precise measurement of the length of the transferred data, rather than on timers.

摘要： Disclosed is a method, system, and article of manufacture for processing modified meta data for data recovery operations. The meta data provides information on user data maintained in a storage device. The system determines whether meta data tracks maintained in a cache were modified and indicates in a non-volatile memory that the determined meta data tracks were modified. Data recovery operations may be initiated as a result of a system failure, such as a warmstart or coldstart recovery. During such data recovery operations, the system processes the non-volatile memory and the indications of modified meta data tracks therein to rebuild lost meta data tracks in the cache.

摘要： Disclosed is a system for caching data. After determining a sequential access of a first memory area, such as a direct access storage device (DASD), a processing unit stages a group of data sets from the first memory area to a second memory, such as cache. The processing unit processes a data access request (DAR) for data sets in the first memory area that are included in the sequential access and reads the requested data sets from the second memory area. The processing unit determines trigger data set from a plurality of trigger data sets based on a trigger data set criteria. The processing unit then stages a next group of data sets from the first memory area to the second memory area in response to reading the determined trigger data set.

摘要： A method for operating a controller for a plurality of direct access storage devices to minimize rotational misses during data transfer operations. Transferred data is staged into a controller cache when a rotational position sensing miss avoidance reconnection is made. Circumstances are detailed for qualifying an operation pending on direct access storage devices for treatment as miss avoidance candidates. Adjustment of controller response depending upon foreknowledge that a channel command word chain includes a write operation is also accomplished utilizing the present method.

摘要： Provided are a method for selecting a path comprising ports on primary and secondary clusters to use to transmit data at a primary volume to a secondary volume. A request is received to copy data from a primary storage location to a secondary storage location. A determination is made from a plurality of primary clusters of an owner primary cluster for the primary storage location, wherein the primary clusters are configured to access the primary storage location. A determination is made as to whether there is at least one port on the owner primary cluster providing an available path to the secondary storage location. One port on the owner primary cluster is selected to use to copy the data to the secondary storage location in response to determining that there is at least one port on the owner primary cluster available to transmit to the secondary storage location.

摘要： Provided are a method, system, and article of manufacture for maintaining information of a relationship of target volumes comprising logical copies of a source volume. Information is maintained on a source volume having a plurality of data units and a plurality of target volumes created at different points-in-time maintaining a logical copy of the data units in the source volume for the different points-in-time. A source downstream pointer is generated for each data unit in the source volume to point to a corresponding data unit in a first target volume. For each target volume data unit whose data is maintained in the source volume or another one of the target volumes, a first upstream pointer is generated indicating one of the source and target volumes from which the target volume data unit inherits data. For each target volume data unit whose data is maintained in the source volume or another one of the target volumes, generating a second upstream pointer indicating one of the source and target volumes having the data for the data unit.

An image of data is maintained in a memory, wherein the image in the memory includes a generation number. The image in the memory is written to at least two copies of the image to storage locations in response to a first event, wherein the generation number for the image in the memory is stored in the storage locations having the copies of the image. A check generation number is stored in a storage location. The image is loaded from at least one of the copies of the image in one of the storage locations to the memory in response to a second event. The generation number for the image loaded into the memory. The check generation number is incremented in response to the second event. The generation numbers for the copies of the image in the storage locations and the check generation number are used to validate the copies of the image.
