● To ensure success of an online update, select a period of low I/O activity. This helps the update complete as quickly as
possible and avoids disruptions to host and applications due to timeouts. Attempting to update a storage system that is
processing a large, I/O-intensive batch job will likely cause hosts to lose connectivity with the storage system.
Updating controller module firmware
In a dual-controller system, both controller modules should run the same firmware version. Storage systems in a replication
set should run the same or compatible firmware versions. You can update the firmware in each controller module by loading a
firmware file obtained from the enclosure vendor.
Update controller module firmware
Perform the following steps to update the controller module firmware:
1. Obtain the appropriate firmware file, and download it to your computer or network.
2. In the PowerVault Manager, prepare to use FTP/SFTP:
a. Determine the network-port IP addresses of the system controllers. See Configuring controller network ports.
b. Verify that the FTP/SFTP 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/SFTP interface permissions. See Adding,
modifying, and deleting users.
3. If the storage system has a single controller, stop I/O to disk groups before starting the firmware update.
4. Open a Command Prompt (Windows) or a terminal window (UNIX) and go to the directory containing the firmware file to
load.
5. Type:
sftp -P port controller-network-address or
ftp controller-network-address
For example:
sftp -P 1022 10.235.216.152 or
ftp 10.1.0.9
6. Log in as a user with manage role permissions and FTP/SFTP interface permissions.
7. Type:
put firmware-file flash
CAUTION:
Do not perform a power cycle or controller restart during a 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.
NOTE: If you attempt to load an incompatible firmware version, the message *** Code Load Fail. Bad format
image. *** is displayed and after a few seconds the FTP/SFTP prompt is redisplayed. The code is not loaded.
Firmware update typically takes 10 minutes for a controller having current CPLD firmware, or 20 minutes for a controller
with downlevel CPLD firmware. If the controller enclosure has attached enclosures, allow additional time for each enclosure
management processor (EMP) to be updated in the expansion module. It typically takes 2.5 minutes for each EMP in a drive
enclosure.
NOTE:
If you are using a Windows FTP/SFTP client, during firmware update a client-side FTP/SFTP application issue or
timeout setting can cause the FTP/SFTP session to be aborted. If this issue persists, try using the PowerVault Manager
to perform the update, use another client, or use another FTP/SFTP application.
If the Storage Controller cannot be updated, the update operation is canceled. If the FTP/SFTP prompt does not return,
quit the FTP/SFTP session and log in again. 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, the FTP session returns to the sftp> prompt, and the FTP/SFTP
session to the local MC is closed. Use a management interface to monitor the system and determine when the update is
complete.
If the Partner Firmware Update (PFU) feature is enabled, allow an extra 5 minutes to 20 minutes for both controllers to be
updated.
