摘要： A mechanism is provided in a storage control unit in a data processing system for providing unsolicited global disconnect requests to users. The mechanism stores lock control data in the storage control unit. The storage control unit allocates its resources into a plurality of clusters. Responsive to a given user connecting to a given partition that is for a logical subsystem resident on a first cluster within the plurality of clusters, the mechanism sends reflected partition information from the first cluster to a second cluster within the plurality of clusters. Responsive to the first cluster experiencing a failure condition, the mechanism moves control data from one or more logical subsystems from the first cluster to the second cluster and for each logical subsystem that moved from the first logical subsystem to the second logical subsystem and that has reflected partition information, presents unsolicited status to one or more users.

摘要： Deleting a data volume from a storage system and freeing its storage space to make it available to be allocated to a new volume is accomplished by only zeroing associated metadata for the tracks contained in the freed storage space which is then reused in a new volume allocation and an attempt is made by the new volume to read a first record R0 of a track. A determination is made as to whether a first user record R1 of the volume is stale If the first record R0 is stale. If record R1 is stale, the metadata or track format description (TFD) is modified whereby the entire track is indicated as being uninitialized and the first record R0 is uninitialized. If record R1 is not stale, the first record R0 is regenerated and the TFD is modified whereby the entire track is indicated as being initialized.

摘要： In a data processing system, configured utility devices are designated in logical storage subsystems. The identification numbers of the designated utility devices are stored by a network interface. When a non-device specific command or query is received from a server by the interface, the interface obtains the ID of one of the utility devices and uses the utility device to address the command or query to the controller. Consequently, the overhead and delays associated with repeated command rejections due to unconfigured devices is substantially reduced.

摘要： An apparatus, system, and method for generating an advanced function usage planning report. One embodiment of the apparatus includes a detection module, a monitoring module, and a planning report module. The detection module detects use of an advanced function on a storage controller. The advanced function includes an optional storage function beyond a standard function set. The monitoring module monitors the use of the advanced function on the storage controller. The planning report module generates a planning report based at least in part on use information from the monitored use of the advanced function.

摘要： Provided are a computer implemented method, computer program product, and system for creating a consistency group. For each source volume that has an instant virtual copy relationship with a target volume, an indicator for the source volume is set to true in a Fast Incremental with Freeze (FIF) map. The consistency group for each source volume whose indicator is set to true in the FIF map and each associated target volume is created by: performing a quick Instant Virtual Copy (IVC) freeze command to freeze each source volume whose indicator is set to true in the FIF map and performing a consistency group created command to thaw each source volume whose indicator is set to true in the FIF map.

摘要： A method for invalidating metadata associated with a target count-key-data (CKD) volume is disclosed. The method initially receives a command for a target CKD volume. The command is either an “establish” command for establishing a point-in-time copy relationship, or a “withdraw” command for withdrawing a point-in-time copy relationship. The method determines a track range, spanning a number of data tracks in the CKD volume, associated with the command. Each data track in the track range is associated with a metadata track. For each metadata track whose associated data tracks are fully contained in the track range, the method performs a first procedure. For each metadata track whose associated data tracks are not fully contained in the track range, the method performs a second procedure different from the first procedure. A corresponding apparatus and computer program product are also disclosed.
