BMC Changes for DGX H100/H200 Systems#

Updated OpenSSH to version openssh-10.0p1-2.
Incorporated security fixes in bootloader to address squashfs vulnerabilities.
Resolved an issue where fans were running at maximum speed.
Resolved an issue where differing time zone settings between the BMC and HMC caused continuous communication recovery attempts.
Enhanced BMC stability.

Improved handling for firmware update of PSUs.
Improved reporting on ERoT status.
Provided multiple stability fixes.
Improved user management in Redfish.
Enhanced stability in communication between the BMC and the HMC.
Corrected power supply sensors where no readings were shown.
Fixed the inability to query GPU firmware version via Redfish.
Addressed an issue where some telemetry information from the GPU tray was unavailable.
Resolved an issue related to chassis power cycling using Redfish.
Corrected fan readings so the fan will reflect 0 if it is not present or stops spinning.
Fixed an issue where NIC information was allocated to the incorrect device in Redfish.

Fixed where BMC configuration might reset after upgrading.
Added Redfish API support for creating, modifying, and deleting power policies.
Support for deploying firmware update using the Web UI.
Redfish Disable Host Interface: keeps redfish functional from BIOS to BMC but prevents the direct path from OS to BMC.
Added ability to specify intermediate certificate authorities in a provisioned certificate chain.
Included additional Redfish metrics reports.
Fixed SNMP, syslog, and rsyslog issues.
Added per BMC AES key for encrypting user/password files during the configuration save and restore process.
Fixed invalid domain issues in the LDAP/AD settings.
Enhanced Redfish diagnostics.
General performance improvements in Redfish APIs and IPMI.
Added support for ConnectX-7 temperature sensors.
Improved resolution for energy counters.
Enhanced Remote Media with support for port numbers and domain names.
General improvements to the Web UI.

Fixed where SEL logs might fill up for NVMe drives
Fixed low occurrence where HMC might not be visible in the BMC after BMC reboot
Ability to control IPMI visibility for Host (Allow All, Limited Command, Hide)
Higher resolution for CPU and GPU energy telemetry via Redfish
Improved reliability of Redfish inventory
Improved overall stability of telemetry collection and handling invalid/missing values
General improvements to WebUI

WebUI enhancements
Enabled GPU Info in WebUI
Enabled NVRAM clear via Redfish
Disabled RMCP / MD5 Auth Support after factory reset
Enabled EROT background copy
Enabled default SNMPv3 MIB
The BMC update includes software security enhancements. Refer to the NVIDIA DGX H100 - August 2023 Security Bulletin for details.

Fixed an issue where the total memory size from the free -m command output is smaller than installed.
Updated to display full device path for HDD devices under the Redfish BootOptions page.
Fixed an issue to mandate administrator password after version 24.09.1 if SED drive is encrypted.

DIMM that experienced uncorrectable errors at runtime will be mapped out on the next boot.
Exposed the C1AutoDemotion, C1AutoUnDemotion, and C6Enable setup options.
Moved the CPU setup options page to under the Advanced page in the setup UI.
Added a setup option to restrict host access via IPMI.
Provided the NvramVarsProtectionInOs setup option to prevent the OS from changing the NVRAM at runtime.
Implemented uncorrectable error rate limiting, disabled CSMI (correctable system management interrupts) on error flooding and on the core that reported MLC (middle-level cache) yellow state, and SEL logging when ANF (advisory non-fatal error) threshold was crossed.
Changed the SncEn default setting to disable.

An activation command (RF_PWR_STATUS) has been introduced to provide reliable insight into system power, making firmware updates, maintenance, and monitoring much safer and more efficient.
Introduced flint support for updating firmware directly on the host system.
A delay mechanism (Update_Delay feature) has been introduced to avoid memory overload and keep simultaneous BMC/HMC updates running smoothly.
Support added for OEM parameter support for firmware updates using the --oem_parameters option.
Tarfile support for PowerShelf update packages has been restored.

Extended show_version to support parallel queries across multiple systems and provide multi-package output.
Added Ctrl-C handler for clean termination of multithreaded operations.
Deprecated support for tarfile update packages.
Upgraded the Python runtime from 3.7 to 3.12.

Added support for parallel firmware updates through the YAML configuration file.
Added the --json option to the update_fw, show_update_progress, and force_update commands.
Added IPv6 support.
Deprecated the targets sub-option for multi-target input. Use config.yaml input instead.

Improved log sanitization to mask the IP address and login credentials by default.
Added support for the --target and --package override from the command-line interface (CLI) using a configuration file.
Enhanced the --target option with the servertype sub-option to resolve unidentified platform errors.

Support for abbreviated firmware update package names.
Enhanced the show_update_progress output to provide a full status report for Redfish.
Support for custom log file path.
The command exits with an error code 1 for any update failure or tool failure.

You can update all the system components on the motherboard tray at one time. Previously, you had to update the components individually.
You can create a JSON file with network addresses and credentials for multiple systems and automatically update multiple systems serially. Refer to Updating Multiple Systems for more information.
