    摘要： Provided are a method, system, and program for initiating and using information used for a host, control unit, and logical device connections receiving a request to create a host port to control unit port connection. In a volume group data structure, a volume group entry is defined having a plurality of pointers for the host port and control unit port pair. At least one device address is added to the volume group that is accessible to the host port and control unit port connection by initializing at least one pointer in the volume group entry to address at least one device data structure. For each of the at least one device addresses, indication is made in the at least one device data structure addressed by the at least one pointer in the volume group entry that the device address is accessible to the host port and control unit port connection.

    摘要： Disclosed are a method and system for a storage controller to manage the allocation of emulated storage devices to physical storage segments. The space within the emulated devices is identified by a logical address. The storage controller is in communication with at least one host device and at least one physical storage device. A plurality of tables, each having entry spaces to store segment identification or segment table and entry identification, is established in the storage controller. The tables define a tree structure by which a segment to be accessed is identified by mapping a logical address through the tables to a segment identification. The number of tables, the number of pages in each table, and the number of entries in each page are selected to optimize the amount of space in the storage controller required by the tables and to ensure that the segments may be allocated in any proportion among the emulated storage devices, including all of the segments being allocated to a single emulated device. Moreover, the allocation of segments to emulated storage space is dynamic by changing the contents of the tables.

    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.
