Abstract: Provided are a method, system, article of manufacture, and a computer program for using priority to determine whether to queue an Input/Output (I/O) request directed to storage. A maximum number of concurrent requests directed to a storage is measured. The measured maximum number of concurrent requests is used to determine a threshold for a specified priority. Subsequent requests of the specified priority directed to the storage are allowed to proceed in response to determining that a current number of concurrent requests for the specified priority does not exceed the determined threshold for the specified priority. Subsequent requests directed to the storage having a priority greater than the specified priority are allowed to proceed. Subsequent requests directed to the storage having the specified priority are queued in a queue in response to determining that the current number of concurrent requests for the specified priority exceeds the overall threshold.

Abstract: A state of an input/output (I/O) operation in an I/O processing system is determined. A request for performing the I/O operation is received from an I/O operating system at a channel subsystem and forwarded to a control unit controlling an I/O device for executing the I/O operation. After a predetermined amount of time passes without receiving indication from the control unit that the I/O operation is completed, an interrogation request is received at the channel subsystem from the I/O operating system for determining the state of the I/O operation. An interrogation command is sent from the channel subsystem to the control unit. A response is received from the control unit, the response indicates a state of the I/O device executing the I/O operation, a state of the control unit controlling the I/O device executing the I/O operation, and the state of the I/O operation being executed.

Abstract: Provided are a method, system, and article of manufacture, wherein a primary storage control unit receives an information unit from a remote host over a fibre channel connection, wherein persistent information unit pacing is implemented over the fibre channel connection. Information is maintained on how many large writes have been received at the primary storage control unit over at least one logical path established over the fibre channel connection between the primary storage control unit and the remote host, wherein a large write is an input/output (I/O) operation for which a number of data information units that are processed exceeds a default value of an information unit pacing credit. The primary storage control unit adjusts an information unit pacing parameter included in a response sent from the primary storage control unit to the remote host, wherein the adjusting is based at least on the information maintained on how many large writes have been received at the primary storage control unit over the at least one logical path.

Abstract: Provided are a method, system, and a computer program product for determining whether to use a repository to store data updated during a resynchronization. Writes to a primary storage are transferred to a secondary storage. A logical copy of the secondary storage as of a point-in-time is established. Writes to the secondary storage in the logical copy received from the primary storage during a logical copy duration after the point-in-time are stored in a repository that comprises less storage space than the secondary storage in the logical copy. The transferring of writes to the secondary storage is suspended. During the suspension writes to the primary storage are indicated in an out-of-synch data structure. A determination is made as to whether available storage space in the repository is sufficient to store writes transferred from the secondary storage while transferring the writes from the out-of-synch data structure in response to ending the suspension of the transferring of writes from the primary to the secondary storages. The repository is used to store data in the secondary storage as of the point-in-time that is to be updated by writes transferred from the primary storage following the ending of the suspension in response to determining that the available storage space in the repository is sufficient to store writes transferred from the secondary storage while transferring the writes indicated in the out-of-synch data structure.

Abstract: An apparatus, system, and method are disclosed for concurrently relocating a RAID array. The apparatus includes an identification module, a designation module, and an implementation module. The identification module identifies an availability of a physical device within a donor arrayed storage device to offload a source drive of a relocation enclosure. The designation module designates an available physical device as a target drive and thereby designate the target drive and the source drive as a linked pair. The implementation module implements a mirroring relationship between the target drive and the source drive. The apparatus, system, and method provide a dynamic relocation of the raid array, minimizing system downtime and maximizing efficient utilization of system resources.

Abstract: An apparatus, system, and method are disclosed for communicating binary data using a self-descriptive binary data structure. The binary data structure also may be referred to as a microcode reconstruct and boot (MRB) image. The binary data structure includes a plurality of data segments, a target data set, and a data structure descriptor. Each of the data segments has a data segment header and data field. The target data set is stored within the data field and may be an executable. The data structure descriptor is descriptive of the binary data structure and identifies the location of the target data set within the data field. The binary data structure is self-descriptive in that the location of an individual target data set may be identified by the data structure descriptor.
