Abstract: A data storage system executes a system management component initiating and monitoring a multi-task job affecting a storage resource such as a storage device. Execution includes maintaining a job data object and a set of task data objects for the multi-task job. A task operates upon the storage resource has a respective task data object containing an identifier of the storage resource as a task-affected storage resource. The job data object is used by a job-level function (e.g., job level of a management GUI) and initially lacks the identifier of the storage resource. During execution, the identifier of the storage resource is copied from the task data object to the job data object as an identifier of a job-affected storage resource, which is then used in subsequent performance of the job-level function (e.g., displaying a hyperlink for the storage resource in a job-level screen of the management GUI).
