The overall workflow to upgrade firmware for PowerScale is shown in Figure 14. The rolling firmware upgrade part is only for the PowerScale OneFS prior to 8.2.0. For OneFS 8.2.0, all the three options, rolling, simultaneous, and intermediate firmware upgrade are available.
Step 1: It is required to install a firmware package prior to being able to upgrade. Starting from OneFS 8.0, use isi upgrade patches for this purpose. The following is an example:
isi upgrade patches install --simultaneous <firmware path>
Note: Since no reboot or service restart required for firmware patch install, Dell Technologies recommends using simultaneous parameter to go faster.
Step 2: Prior to OneFS 8.2.0, the only option is to run a rolling firmware upgrade. In OneFS 8.2.0, a new tool, isi_upgrade_helper is introduced. You can use the following command to leverage to tool to give recommendations:
isi_upgrade_helper
The output of this tool includes three recommendations and the corresponding CLI command as introduced earlier in this section.
Step 3: Choose a recommendation from the helper tool and run the firmware upgrade command according to the recommendation.
If running a simultaneous firmware upgrade, repeat the command: isi_upgrade_helper once the firmware upgrade is complete to obtain the next set of nodes to upgrade. Repeat until no firmware mismatches remain. To check the firmware mismatch, use the following commands and exam the Mismatch column.

Note: You may see Upgrade framework is re-gathering firmware status, please try again as the response to isi upgrade firmware devices. This is normal behavior.
From OneFS 9.0.0, the tool isi_upgrade_helper is removed and the node firmware upgrade process has been simplified. The overall workflow is:
The following example shows how it works in OneFS 9.0.0
# isi upgrade firmware assess --fw-pkg /ifs/<node_firmware_package>.tar
Note: The assessment may take an extended amount of time to complete based on cluster size, activity, platform types, and so on.
# isi_upgrade_logs --get-fw-report
# isi upgrade cluster firmware start --fw-pkg=/ifs/<node_firmware_package>.tar
Note: In OneFS 9 and OneFS 9.1 releases, to perform a 'Balanced/Parallel' or 'Fastest/Simultaneous' node firmware update, run the commands provided in the results of the firmware assessments.
