Updating firmware
Hewlett Packard Enterprise recommends that all firmware on all devices in your system be updated to the
latest version after hardware installation is complete. Hewlett Packard Enterprise also encourages you to
check back often for any updates that might have been posted.
There are two methods for updating the complex firmware; using HP SUM or manually.
Prerequisites
Before updating firmware, Hewlett Packard Enterprise strongly recommends implementing these security
best practices:
• Isolate the management network by keeping it separate from the production network and not putting it
on the open internet without additional access authentication.
• Patch and maintain LDAP and web servers.
• Run latest virus and malware scanners in your network environment.
Installing the latest complex firmware using HP SUM
The HP SUM utility enables you to deploy firmware components from either an easy-to-use interface or a
command line. It has an integrated hardware discovery engine that discovers the installed hardware and
the current versions of firmware in use on target servers. HP SUM also has logic to install updates in the
correct order and ensure all dependencies are met before deployment of a firmware update. It also
contains logic to prevent version-based dependencies from destroying an installation and ensures
updates are handled in a manner that reduces any downtime required for the update process. HP SUM
does not require an agent for remote installations.
HP SUM is included in the downloadable firmware bundles.
For more information about HP SUM, see the HP Smart Update Manager User Guide (http://
www.hpe.com/info/hpsum/documentation).
NOTE:
You can also update firmware manually. There are different firmware bundles for each method. See
the detailed instructions provided in the release notes for the firmware bundle for more information
about manually updating firmware. Also see Manually updating the complex firmware on page
34.
Manually updating the complex firmware
To manually update the complex firmware, you will:
Procedure
1. Download the firmware bundle.
2. Update the complex and nPartition firmware.
3. Update I/O firmware and SMH and WBEM providers.
4. Be sure to use only the recommended I/O firmware to avoid incompatibility with other system
firmware.
5. Check for driver and firmware updates for other devices.
To use HP SUM to update the complex firmware, see Installing the latest complex firmware using HP
SUM on page 34.
