expansion module enclosure management processor (EMP) to be updated. This task typically takes 2.5 minutes for each
EMP in a drive enclosure.
If the Storage Controller cannot be updated, the update operation is canceled. Verify that you specified the correct
firmware file and repeat the update. If this problem persists, contact technical support.
When firmware update on the local controller is complete, users are automatically signed out and the MC restarts. Until
the restart is complete, sign-in pages say that the system is currently unavailable. When this message is cleared, you may
sign in again.
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 firmware
You can update disk firmware by loading a firmware file obtained from your reseller.
Disks can be updated from either controller.
NOTE: Disks of the same model in the storage system must have the same firmware revision.
