Update HDM firmware

Restrictions and guidelines

Only one user can update firmware at a time. If multiple users attempt to update firmware, only the one who first started the update can perform this operation. When you successfully start a firmware update, HDM automatically signs out all the other users that try to start a firmware update.

Do not refresh the HDM webpage during the update.

For the firmware to be updated successfully, do not perform the following tasks from the Web interface during the update process:

·     Change network settings, including dedicated and shared network ports, VLAN, network port mode, Ethernet adapter, DNS, and network port mode.

·     Configure NTP settings.

·     Configure security settings, including access service, firewall, and SSL.

·     View the device power status or change power capping settings.

·     Perform the following maintenance tasks:

¡     Import or export configuration.

¡     Restore the factory default.

¡     Restart HDM.

¡     Perform primary/backup switchover.

¡     Restart CPLD.

To avoid HDM or operating system errors, do not power on, power off, or power cycle the device during the update.

The following remote console menus are not available during the update:

·     Keyboard menu in the KVM console.

·     Send Keys and Hot Keys menus in the H5 KVM console.

Update HDM firmware from HDM

HDM supports one primary firmware image and one backup firmware image, and it always runs the primary image. HDM firmware update updates the backup firmware image.

To minimize the impact on HDM services, HDM uses the following procedure to update HDM firmware:

1.     When you update HDM firmware, HDM replaces the backup firmware image with the uploaded update image.

2.     At the restart after the update, HDM changes the roles of primary and backup HDM images. Then, HDM restarts with the update image, which is now the primary image.

For more information about primary/backup switchover, see HDM online help.

Prerequisites

·     Sign in to the HDM Web interface. For more information, see "Sign in to HDM."

·     Obtain the up-to-date HDM firmware image from the H3C website, and store the image file on the local PC. To avoid update failure, make sure the update image file contains a vendor signature and is not corrupt.

·     To avoid configuration loss caused by inadvertent mistakes, back up the HDM configuration file.

Procedure

1.     In the navigation pane, select Maintenance > Update Firmware.

Figure 7 Update Firmware page

 

2.     In the work pane, perform the following tasks:

a.     Select an image upload method.

-     If you select Local, select HDM as the firmware type. Then, browse to the update image file and select it.

-     If you select TFTP, enter the IP address of the interface used for file upload and enter the image name. Then, select HDM as the firmware type.

b.     Select the HDM restart method after the update is complete. You can have HDM automatically restart when the update is complete or manually restart HDM later.

c.     (Optional.) To remove all user-configured settings after you update HDM firmware, select Enabled for Restore factory default.

d.     Click Next.

 

	CAUTION: The Restore factory default option removes all user configured settings when HDM starts up with the new firmware. When you select this option, make sure you understand its impact on the services. If this option is selected, you must use the default user account settings at the first sign-in to HDM after its firmware is updated.

 

3.     Verify that the new firmware image version is correct, and then click Next.

The firmware update starts and the system displays the update progress.

4.     Follow the system instructions to complete the update.

5.     If you selected manual restart, restart HDM manually. For more information, see HDM online help.

If you selected automatic restart, HDM restarts automatically.

6.     To update the backup image, perform a primary/backup switchover, and then repeat the update process.

7.     Re-sign in to HDM. Verify that the HDM firmware image has been updated.
