摘要： One general aspect of asynchronous local and remote generation of consistent point-in-time snap copies in consistency groups in accordance with the present description, is directed to receiving a local-remote pair point-in-time snap copy establish command to establish a local point-in-time snap copy in a local data storage system, and a remote point-in-time snap copy in a remote data storage system. In one aspect, establishment of the remote point-in-time snap copy relationship may be delayed as a function of the state of a consistency group formation process upon receipt of the local-remote pair point-in-time snap copy establish command. As a result, consistency of the local-remote pair of point-in-time snap copies may be realized, notwithstanding an asynchronous relationship between the local and remote storage systems. Other features and aspects may be realized, depending upon the particular application.

摘要： A primary storage controller receives an input/output (I/O) command from a host, wherein a host timestamp is associated with the I/O command. During a mirroring of storage volumes to a secondary storage controller, the primary storage controller communicates the host timestamp associated with the I/O command to the secondary storage controller, wherein mirrored copies of the storage volumes are timestamped based on at least the host timestamp and an elapsed time since a last host I/O command. A recovery is made from a failure of one or more of the storage volumes in the primary storage controller, by using the timestamped mirrored copies of the storage volumes.

摘要： Systems and methods for metadata tag inheritance are disclosed. The methods include maintaining a plurality of data storage systems including at least one tiered data storage system in communication with an external metadata management system, operating the metadata management system to store metadata corresponding to data residing on the plurality of data storage systems as a plurality of entries, detecting an execution of a data operation command in the tiered data storage system that causes movement of a data set from a source storage tier to a destination storage tier, and in response to detecting the execution of the data operation command, operating the metadata management system to create a new metadata entry corresponding to the execution of the data operation command. The new metadata entry includes at least one custom tag created before the execution of the data operation command.

摘要： Provided is a method for managing operation requests using different resources. In one embodiment, a first queue is provided for operations which utilize a first resource of a first and second resource. A second queue is provided for operations which utilize the second resource. An operation is queued on the first queue until the first resource is acquired. The first resource is released if the second resource is not also acquired. The operation is queued on the second queue when the first resource is acquired but the second resource is not. In addition, the first resource is released until the operation acquires both the first resource and the second resource.

摘要： Consistency groups are asynchronously copied to a remote computational device, from a local computational device, wherein point in time copy operations are performed at the local computational device while the consistency groups are being asynchronously copied to the remote computational device. Indicators are stored at the remote computational device to identify those point in time copy operations that are to be restored as part of a recovery operation performed at the remote computational device in response to a failure of the local computational device.

摘要： Withdrawal of a point-in-time snap copy relationship or a portion of such a relationship, is managed in a manner which can obviate disruption of consistency groups due to the withdrawal. If the withdrawal request is directed to a subrange of the original snap copy relationship, the snap copy relationship is split by creating one or more point-in-time snap copy relationships over one or more subranges of tracks of the snap copy source. A determination is made as to whether to delay execution of the withdrawal request to temporarily preserve data of the withdrawal range. Disruptions to completion of consistency groups may be avoided by selectively delaying the withdrawal of a snap copy relationship corresponding to the withdrawal subrange. In so far as the host is involved, a host may treat the withdrawal request as immediately granted without delay. Other aspects may be realized, depending upon the particular application.

摘要： Provided are a computer program product, system, and method for asynchronous pausing of the formation of consistency groups. A first copy operation is initiated to copy the source data from the first storage to the first data copy in the second storage. A second copy operation is initiated to copy the first data copy in the second storage to a second data copy in response to forming a consistency group of the source data at the first data copy forms consistent as of a point-in-time with respect to the source data. The first copy operation is suspended to allow for further processing of the first data copy in response to completing the second copy operation. The formation of a next consistency group is restarted between the source data and the first data copy in response to receiving a resume command.

Each of the plurality of entries may include one or more custom tags, and the new metadata entry may include at least one custom tag created before the execution of the data operation command.

摘要： Systems and methods for metadata tag inheritance during backup are disclosed. The method includes maintaining a plurality of data storage systems in communication with an external metadata management system, operating the metadata management system to store metadata corresponding to data residing on the data storage systems as a plurality of entries that include or more custom tags, detecting an execution of a backup data operation command on data residing in a data storage system that causes creation of a backup copy of a data set in that data storage system in a destination data storage system, and operating the metadata management system to create a new metadata entry corresponding to the execution of the backup data operation command in response to detecting the execution of the backup data operation command. The new metadata entry includes at least one custom tag created before the execution of the backup data operation command.
