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： Provided are a method, system, and program for reassigning storage volumes from a failed processing system to a surviving processing system. A first processing system detects a failure of a second processing system. The first processing system determines device groups of storage devices managed by the failed second processing system and determines for each determined device group, hosts that connect to storage devices in the device group. The first processing system sends, for each device group, a unit check to each determined host indicating failure of each device group through one storage device in the device group to which the determined host connects. The determined hosts execute instructions to terminate any I/O operations in progress on the storage devices in the device group in response to the unit check indicating failure of one storage device in the device group and issue, a command to one storage device for the device group to end the busy condition.

摘要： Provided are a system and article of manufacture for providing an address format compatible with different addressing formats used for addressing different sized address spaces. An address format is used in an operating system to address storage space in a storage device comprising a first region and a second region of storage space. A first group of applications uses the address format to only address the storage space in the first region and is not coded to use the address format to access the second region and a second group of applications uses the address format to address the storage space in the first and second regions.

摘要： Disclosed is a system and program for selecting one of multiple proposed paths to a device. For each proposed path, a determination is made of a number of components the proposed path shares with existing paths to the device. The components comprise points of failure such that if one component fails then the path including the component fails. The determined number of shared components for each proposed path is used to select one proposed path.

摘要： Provided are a method, system, and article of manufacture for receiving an initial request from a first device to a second device. A response to the initial request is received from the second device to the first device. Each response and request received from the first device to the second device is processed by accessing the response or request from a packet encoded using a first communication protocol; generating a packet including the accessed response or request into a packet encoded using a second communication protocol; and transmitting the generated packet to the second device. Each response and request received from the second device to the first device is processed by accessing the response or request from a packet encoded using the second communication protocol; generating a packet including the accessed response or request into a packet encoded using the first communication protocol; and transmitting the generated packet to the second device.

摘要： Provided are a method, system, and article of manufacture for removing alias addresses from an alias address pool. A plurality of alias addresses are assigned to an alias address pool, wherein the alias addresses in the alias address pool are capable of being dynamically assigned to a device to service I/O requests to the device. An operation is initiated by a process to remove a specified alias address from the alias address pool. An indicator is set to prevent additional processes from removing one alias address from the alias address pool in response to initiating the operation. The specified alias address is removed from the alias address pool.

摘要： Error recovery is performed when an error rate for a subsystem of a computer environment (e.g., an Input/Output (I/O) subsystem) is greater than a predefined value and a critical resource of the computer environment (e.g., storage) is experiencing a shortage. Error recovery may include slowing down activity of the devices associated with the subsystem and/or simulating errors for the subsystem. The simulation of the errors does not require a large block of additional storage, and thus, the shortage situation is not exacerbated.

摘要： Disclosed is a system and method for processing a data access request (DAR). A processing unit, such as a storage controller, receives a DAR, indicating data to return on a channel, such as a channel connecting to a host system, and priority information for the received DAR. The processing unit retrieves the requested data for the received DAR from a memory area, such as a cache or direct access storage device (DASD), and determines whether there is a queue of data entries indicating retrieved data for DARs to transfer on the channel. The queued DARs include priority information. The processing unit processes at least one data entry in the queue, the priority information for the data entry, and the priority information for the received DAR to determine a position in the queue for the received DAR. The processing unit then indicates that the received DAR is at the determined position in the queue and processes the queue to select retrieved data to transfer on the channel to the host system.
