If PFU is enabled, allow as additional 10 minutes to 20 minutes for the partner controller to be updated.

5. Clear your web browser cache, then sign in to the PowerVault Manager. If PFU is still running on the controller you sign in to, a panel

shows PFU progress and prevents you from performing other tasks until PFU is complete.

NOTE: If PFU is enabled for the system, after firmware update has completed on both controllers, check the system

health. If the system health is Degraded and the health reason indicates that the firmware version is incorrect, verify

that you specified the correct firmware file and repeat the update. If this problem persists, contact technical

support.

Updating expansion module firmware

An expansion enclosure can contain one or two expansion modules. Each expansion module contains an enclosure management processor

(EMP). When you update controller-module firmware, all expansion modules are automatically updated to a compatible firmware version.

Prepare to update expansion module firmware

1. Follow the best practices in Best practices for firmware update.

2. Obtain the appropriate firmware file and download it to your computer or network.

3. If the storage system has a single controller, stop I/O to the storage system before starting the firmware update.

Update expansion module firmware

1. Perform one of the following:

• In the banner, click the system panel and select Update Firmware.

• In the System topic, select Action > Update Firmware.

The Update Firmware panel opens.

2. Select the Update Expansion Modules tab. This tab shows information about each expansion module in the system.

3. Select the expansion modules to update.

4. Click File and select the firmware file to install.

5. Click OK. Messages show firmware update progress.

CAUTION:

Do not perform a power cycle or controller restart during the firmware update. If the update is

interrupted or there is a power failure, the module might become inoperative. If this occurs, contact technical

support. The module might need to be returned to the factory for reprogramming.

It typically takes 3 minutes to update each EMP in an expansion enclosure. Wait for a message that the code load has completed.

6. Verify that each updated expansion module has the new firmware version.

Updating disk-drive firmware
