From OneFS 9.2.0.0, node firmware upgrade can be combined into the OneFS upgrade process to make it more efficient and save maintenance windows. The reboot times will be minimized to once per node and in this case to largely reduce the disruption to the workload and clients.
This feature is available in the CLI and WebUI:
# isi upgrade cluster start <install-image-path> --parallel --fw-pkg <path>
Use the parameter --fw-pkg to specify the path for node firmware. Figure 15 demonstrates how to run combined upgrades in the WebUI.
Note: rollback does not revert any applied firmware updates.
