HSM tools February 2025 updates
- 03 February 2025
New versions of the slk_helpers (1.13.2), of pyslk (2.2.0) and of the slk_wrappers (2.0.1) are available which contain several new features and bugfixes. The major changes and improvements are presented here. Details on minor changes can be found in the slk_helpers changelog and the pyslk changelog (pyslk changelog).
We’re excited to announce new commands and scripts designed to simplify data retrieval, following a thorough testing phase with multiple users. We’re aware that large-scale usage could reveal unforeseen challenges, particularly with StrongLink. Therefore, we’ll be actively monitoring system performance and encourage users to provide feedback. This experimental workflow is a collaborative effort, and we’re committed to making it the best possible solution. We’re also working on additional tools to further enhance data transfer to and from the tape archive. If necessary, based on performance data and user feedback, we may adjust or even temporarily deactivate this experimental workflow to ensure system stability and optimal performance.

HSM: check storage location of files
- 11 April 2024
From time to time connection issues between StrongLink and one of the tape libraries occur. If the retrieval of a file fails repeatedly in such a situation, then it is useful to be able to check whether the file is stored on a tape in the affected library. For this purpose we provide the commands slk_helpers resource_tape and slk_helpers tape_library.
Example:

Changes in pyslk 1.9
- 25 August 2023
updated: 2023-09-18 (removed note)
A major structural change was implemented in pyslk version 1.9.0 compared to older versions. The implementation of this change did start in version 1.7.0 but most parts where implemented in 1.9.0. All functions which are meant to be used by end-users, can be used without specifying the module’s name: pyslk.example_function instead of pyslk.module_name.example_function.
