An approach for generating a distribution list. The approach analyzes a message associated with a user to create a message bag of words (BOW). The approach can analyze a history of messages associated with the user to create a plurality of history message BOWs. The approach can calculate similarity factors between the message BOW and the plurality of history BOWs, respectively. If a similarity factor is '>=' a predetermined similarity threshold, the approach can add a history message to a similar message list. The approach can calculate interest factors, based on the similarity factors, for contacts associated with the similarity factors in the similar message list. If an interest factor is “>=” a predetermined interest threshold, the approach can add a contact associated with the interest factor to a suggested contact list. The approach can prioritize the suggested contact list and insert the list as a distribution list.

A method for presenting output returned by a command-line interface is disclosed. In one embodiment, such a method submits, by way of a command-line interface (CLI), a command to retrieve a list of resources. The method further submits, in association with the command, an indicator to compress the list. In response to receiving the command and indicator, the method retrieves the list of resources and compresses the list such that resources with identical attributes are presented as a single tuple in the list. Such a tuple may, in certain embodiments, identify the resources with identical attributes as a range of resources and/or as a comma delimited list of resources. The tuple may also, in certain embodiments, identify how many resources with identical attributes are represented by the tuple. A corresponding system and computer program product are also disclosed.

A method, system, and program product are provided for processing a host write operation during a recovery operation of a point-in-time copy restore. Provided are blocking the host write operation to the source volume based on whether a track on the source volume is copied to the target volume. A host and the point-in-time copy restore synchronize simultaneous access to the track using a track lock on track access, causing a requestor without the track lock to be queued until the track lock is available.

Recovering from a mistaken point-in-time copy restore

According to one embodiment, a computer program product for read-once point-in-time copy includes a computer readable storage medium having program instructions embodied therewith. The computer readable storage medium is not a transitory signal per se, and the program instructions are executable by a storage system manager to cause the storage system manager to perform a method comprising: detecting a read access to one or more data tracks of a target data storage module; setting a value of one or more bits in response to detecting the read access to the one or more data tracks, each of the one or more bits being associated with one of the one or more data tracks. The value of the one or more bits is set to a value configured to prevent a copy-on-write operation being applied to the one or more data tracks to which the read access was detected.

A method is disclosed for avoiding out-of-space conditions in an asynchronous data replication environment. In one embodiment, such a method creates a consistency group on a primary storage system of an asynchronous data replication environment. The method determines a number of additional extents that will be needed on a secondary storage system to accommodate the consistency group. The number of additional extents is compared to a number of free extents on the secondary storage system. In the event the number of additional extents does not exceed the number of free extents, the method transfers the data from the primary storage system to the secondary storage system. In the event the number of additional extents exceeds the number of free extents, the method automatically takes actions on the secondary storage system to provide the number of additional extents. A corresponding system and computer program product are also disclosed.
