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. 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.
Update expansion-module and drawer firmware
Perform the following steps to update the expansion-module and drawer firmware:
1. Obtain the appropriate firmware file, and download it to your computer or network.
2. In the PowerVault Manager, prepare to use FTP:
a. Determine the network-port IP addresses of the system controllers. See Configuring controller network ports.
b. Verify that the FTP service is enabled on the system. See Enable or disable system-management settings.
c. Verify that the user you plan to use has manage role permissions and FTP interface permissions. See Adding, modifying, and
deleting users.
3. If you want to update all expansion modules, go to the next step. Otherwise, in the PowerVault Manager, determine the address of
each expansion module to update:
a. In the Configuration View panel, select a drive enclosure.
b. In the enclosure properties table, note each EMP bus ID and target ID values. For example, 0 and 63, and 1 and 63. Bus 0 is the bus
that is native to a given controller, while bus 1 is an alternate path through the partner controller. Dell EMC recommends
performing update tasks consistently through one controller to avoid confusion.
4. If the system has a single controller, stop I/O to disk groups before starting the firmware update.
5. Open a Command Prompt (Windows) or a terminal window (UNIX) and go to the directory containing the firmware file to load.
6. Type:
ftp controller-network-address
For example:
ftp 10.1.0.9
7. Log in as an FTP user with manage role permissions and FTP/SFTP interface permissions.
8. Perform either of the following tasks:
• To update all expansion modules, type:
put firmware-file encl
• To update specific expansion modules, enter:
put firmware-file encl:EMP-bus-ID:EMP-target-ID
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 issue occurs, contact technical
support. The module might need to be returned to the factory for reprogramming.
It typically takes 2.5 minutes to update each EMP in a drive enclosure. Wait for a message that the code load has completed.
NOTE:
If the update fails, verify that you specified the correct firmware file and try the update a second time. If it
fails again, contact technical support.
9. If you are updating specific expansion modules, repeat step 8 for each remaining expansion module that needs to be updated.
10. Quit the FTP session.
11. Verify that each updated expansion module has the correct firmware version.
Updating disk firmware
You can update disk firmware by loading a firmware file obtained from your reseller.
A dual-ported disk can be updated from either controller.
NOTE: Disks of the same model in the storage system must have the same firmware revision.
