In OneFS 9.2 and later releases, the firmware assessment no longer provides commands needed to perform a 'Balanced/Parallel' or 'Fastest/Simultaneous' node firmware update. The functionality to perform updates in these manners is now built into the firmware update commands as additional arguments. Use the additional argument, --parallel for Balanced/Parallel, --simultaneous for Fastest/Simultaneous, or --rolling for Least Disruptive. For example to run a parallel firmware upgrade, use the following command:
# isi upgrade cluster firmware start --parallel --fw- pkg=/ifs/<node_firmware_package>.tar
