    Abstract: Provided are a computer program product, system, and method for a computer program product, system, and method for determining an availability score based on available resources of different resource types in a distributed computing environment of storage servers to determine whether to perform a failure operation for one of the storage servers. A health status monitor program deployed in the storage servers performs: maintaining information indicating availability of a plurality of storage server resources for a plurality of resource types; calculating an availability score as a function of a number of available resources of the resource types; and transmitting information on the availability score to a management program. The management program uses the transmitted information to determine whether to migrate services from the storage server from which the availability score is received to at least one of the other storage servers in the distributed computing environment.

    Abstract: Exemplary method, system, and computer program embodiments for, in a data storage environment configured for synchronous replication between a primary and secondary pair of storage entities, each having tiered storage devices, extent migration are provided. In one embodiment, by way of example only, a migration instruction is sent, by the primary storage entity, to the secondary storage entity, the migration instruction including a relative priority based on a primary ordered heat map of the tiered storage devices of the primary storage entity. The relative priority is used against a secondary ordered heat map of the tiered storage devices of the secondary storage entity to perform the extent migration, regardless of whether the primary and secondary storage entities are identical.

    Abstract: Provided are a computer program product, system, and method for embedding and executing trace functions in code to gather trace data. A plurality of trace functions are embedded in the code. For each embedded trace function, a trace level is included indicating code to which the trace applies. The trace level comprises one of a plurality of levels. During the execution of the code, the embedded trace functions having one of the levels associated with a specified at least one level specified are executed. The embedded trace functions associated with at least one level not comprising one of the at least one specified level are not invoked.

    Abstract: In accordance with one aspect of the present description, a node of the distributed computing system has multiple communication paths to a data processing resource lock which controls access to shared resources, for example. In this manner, at least one redundant communication path is provided between a node and a data processing resource lock to facilitate reliable transmission of data processing resource lock signals between the node and the data processing resource lock. Other features and aspects may be realized, depending upon the particular application.
