A method for dynamic consistency group formation, in one embodiment, includes creating a snapshot of first data stored on a source storage system with respect to data content and data structure, copying the snapshot to a target storage system, detecting one or more write operations affecting data on the source storage system while copying the first data, detecting one or more collisions affecting the first data on the source storage system, wherein a collision occurs whenever the write operations affect the first data prior to the first data being written, setting a consistency group interval which represents an interval duration between successive snapshot create-and-copy events, and altering the consistency group interval to minimize collisions affecting data on at least one of the storage systems. Other methods for dynamic consistency group formation are also described.

Provided are a computer program product, system, and method for determining whether to extend a drain time to copy data blocks from a first storage to a second storage. A data structure is generated indicating data blocks in the first storage to copy to the second storage. A drain operation is initiated to copy the data blocks indicated in the first storage to the second storage for a drain time period. Write requests to the data blocks indicated in the data structure are queued during the drain time period, wherein the queued write requests are not completed while queued. Metric information based on the writes that occur to data blocks in the first storage are gathered during the drain time period; and in response to expiration of the drain time period, a determination is made from the gathered metric information of whether to continue the drain operation or terminate the drain operation.

In one embodiment, a system, includes logic for creating a snapshot of first data stored on a source storage system, wherein the snapshot is a logical copy of the first data stored on the source storage system with respect to data content and data structure; logic for copying the snapshot to a target storage system; logic for copying the first data represented by the snapshot from the source storage system to the target storage system; logic for detecting one or more write operations affecting data on the source storage system; logic for detecting one or more collisions affecting the first data on the source storage system, logic for setting a consistency group interval; and logic for altering the consistency group interval to minimise collisions affecting data on the source storage system. Other systems and computer program products for dynamic consistency group formation are also described.

A method for executing a software routine identified in a task object is provided. The method includes accessing a list of software routine identifiers associated with software routines that are executable on a computer server. The method further includes generating a task object generation command having at least a first software routine identifier, parameter data, and link task information and generating a second task object in response to the task object generation command. The second task object includes the first software routine identifier, the parameter data, and the link task information. The method further includes adding the second task object to a task execution queue on the computer server and executing the first software routine identified by the first software routine identifier in the second task object on the computer server to obtain at least a first result value, when the first flag value is a first predetermined value and the result parameter associated with the first task object corresponds to a second predetermined value.

A method, system, and computer program product for providing dynamic context assistance to a user of a system, such as a storage system. One or more current command line interface (CLI) entries that are entered in a CLI of the system are received and a current state of the system is determined. Dynamic context assistance is then generated for one or more current CLI entries based on entered values of the one or more CLI entries. In this regard, the dynamic context assistance can be generated and displayed in a text or graphical form when one or more dynamic context assist keys are entered in the CLI in conjunction with the current CLI entry.
