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： Provided are a method, system and article of manufacture for verifying a record as part of an operation to modify the record. A search request is received to determine whether a record matches a value. A first component executes the search request to determine if the record matches the value. The first component sends a verify request to a second component that did not execute the search request to execute the search request to determine whether the record matches the value. A result of the first and second components executing the search request is logged.

摘要： An apparatus, system, and method are disclosed for selecting a space efficient repository. A cache receives write data. A destage module destages the data sequentially to a coarse grained repository such as a stride level repository and destages a directory entry for the data to a coarse grained directory such as a stride level directory if the data satisfies a repository policy. In addition, the destage module destages the data to a fine grained repository such as a track level repository overwriting an existing data instance and destages the directory entry to a fine grained directory such as a track level directory if the data does not satisfy the repository policy.

摘要： An apparatus, system, and method are disclosed for accessing a preferred path through a storage controller. A request module receives a request from a host to identify a preferred path from the host to a control unit image. A response module reports the preferred path to the host. A connection module connects the host through the preferred path to the control unit image. In one embodiment, a detection module detects a failure of a first interconnection module comprising the preferred path. The connection module may re-connect the host to the control unit image through a non-preferred path comprising a second interconnection module in response to the failure of the first interconnection module.

摘要： An apparatus, system, and method are provided for updating a code image. The apparatus, system, and method include a loader for loading a new code image into a temporary memory location separate from the memory location occupied by the old code image. A conversion module of the new code image executes and selectively reconciles incompatibilities between the old code image and the new code image. In one aspect, once incompatibilities are reconciled, a copy module copies the new code image into the memory space occupied by the old code image.

摘要： Provided are a method, system, and program for an adaptor to read and write to system memory. A plurality of blocks of data to write to storage are received at an adaptor. The blocks of data are added to a buffer in the adaptor. A determination is made of pages in a memory device and I/O requests are generated to write the blocks in the buffer to the determined pages, wherein two I/O requests are generated to write to one block split between two pages in the memory device. The adaptor executes the generated I/O requests to write the blocks in the buffer to the determined pages in the memory device.

摘要： Provided are a method, system, and program maintaining and using nexus information on a host, port and device connection. A login is received from a host port on a storage controller port, wherein the host port has been configured on the storage controller to access one or more devices. An entry is added to a host-storage controller ports data structure for the host port and storage controller port involved in the login. At least one pointer is initialized in the entry in the host-storage controller ports data structure to point to at least one entry in at least one intermediate data structure. One pointer is initialized in each entry in one intermediate data structure addressed by one initialized pointer in the host-storage controller ports data structure to point to a nexi data structure having a plurality of entries.

摘要： Provided are techniques for spare device management. Candidate devices are sorted into spare coverage groups by type. One or more candidate devices having closest fitting characteristics of a desired type are identified from the spare coverage groups. The identified one or more candidate devices are assigned to be spare devices for the spare coverage group. It is determined whether a desired number of spare devices have been assigned to the spare coverage group. In response to determining that the desired number of spare devices have not been assigned, a spare device having the closest fitting characteristics for every predetermined number of candidate devices having the closest fitting characteristics is assigned, until the desired number of spare devices having the closest fitting characteristics are assigned.

摘要： Provided are a method, system, and article of manufacture, wherein a command is received at a first computational device coupled to a first adapter that is capable of allowing access to a data storage to the first computational device. The first computational device sends the command to a second computational device. The command is processed by a second adapter coupled to the second computational device, wherein the second adapter allows the second computational device to access the data storage, and wherein the second adapter accesses memory in the first computational device to process the command. In certain embodiments, the first adapter that allows the first computational device to access the data storage has failed.
