Known Issues

N/A

Description: Ownership of RShim may be ambiguous when ownership is forced by a new host causing several BMC features to not work due to the ownership conflict.

Workaround: Reboot the BMC after moving RShim ownership to a new host. This ensures the BMC correctly synchronizes with the current RShim ownership status.

3877835

Description: openbmctool is no longer supported.

Workaround: The supported management interfaces are IPMItool and Redfish.

Discovered in version: 24.07

4027478

Description: BMC's IP aliasing feature allows multiple IP addresses to be assigned to a single network interface, which permits the interface to respond to different IP addresses.

Workaround: N/A

Discovered in version: 24.07

3995907

Description: The Redfish schema for BlueField data ports (Systems/Bluefield/EthernetInterfaces) displays only the valid IP and MAC addresses. Other attributes associated with this schema should be ignored and considered as not current.

Workaround: N/A

Discovered in version: 24.07

3995907

Description: The update to ipmitool version 1.8.19 has introduced inconsistencies between the tool and the BMC implementation, leading to incomplete information being displayed when executing the lan print command.

Workaround: N/A

Discovered in version: 24.07

3995899

Description: The DPU BMC is equipped to detect ECC errors from the BlueField Arm system and record these errors in the BMC SEL. For SEL events related to single-bit ECC errors, the BMC does not recognize the resolution status on the BlueField Arm and consequently logs "Resolved": false irrespective of the actual state.

Workaround: N/A

Discovered in version: 24.07

3925815

Description: When changing the BMC IPv6 address configuration from static to DHCP, the static IP address in the IPv6 list does not get disabled.

Workaround: N/A

Discovered in version: 24.07

3899719

Description: After executing sel clear, the event log in LogServices generates Error.LogsCleared.

Workaround: N/A

Discovered in version: 24.07

4005373

Description: DPU BMC does not support the following attributes and schemas within the Systems/Bluefield Redfish schema: MemorySummary, Memory, Processors, Storage, GraphicalConsole, and PowerMode.

Workaround: N/A

Discovered in version: 24.07

3995906

Description: The BlueField power cycle relies on the PCIe PERST/ALL_STANDBY. If the host does not disconnect the PCIe link, the DPU BMC would cancel the power cycle request to avoid causing server errors. Since the power cycle command is asynchronous, it always returns success; however, if it fails, a new SEL log is created to indicate that the command has not executed.

Workaround: Get the status from the BMC SEL.

Discovered in version: 24.07

3820884

Description: The DPU BMC LLDP represents the eth0 interface. If the user initiates a VLAN interface on top of eth0, the LLDP schema does not function as expected and the transmitted data does not accurately describe the eth0 attribute or the newly created VLAN.

Workaround: N/A

Discovered in version: 24.07

3998661

Description: The ipmitool set static ip command deletes both IPv4 and IPv6 then creates IPv4 static IP, then changes the IPv4 address causing 1 more create and delete events.

Workaround: N/A

Discovered in version: 24.07

3994990

Description: During a power cycle of the BlueField, the ipmb_host driver running on the BlueField OS may crash due to communication issues with the BlueField BMC, causing the BlueField OS to become stuck.

Workaround: Perform an additional reboot or reset to the BlueField.

Discovered in version: 24.01

3725502

Description: Recording user operations takes place regardless of the action's success.

Workaround: N/A

Discovered in version: 24.01

3598450

Description: The boot process may stall following a non-graceful reboot.

Workaround: Do not issue force reboot to the BlueField BMC.

Discovered in version: 24.01

3664596

Description: When declaring only a secondary NTP server, this server acts as the primary one.

Workaround: N/A

Discovered in version: 24.01

3747285

Description: The ipmitool command to force PXE in BMC modifies both the IPMI and Redfish request settings. When Redfish is enabled in UEFI, Redfish takes priority, so all PXE boot entries are attempted and before regular boot continues.

Workaround: Redfish must be disabled if IPMI force PXE retry behavior is expected.

Discovered in version: 24.01

3662417

Description: The Arm UEFI is crucial for rapid system booting, activating the NIC for host network communication. The Arm UEFI tries to fetch Redfish host credentials from the DPU BMC during boot-up. If not done within a designated timeframe, UEFI skips Redfish setup and boots the OS, ignoring any Redfish server settings or updates.

Workaround: Reboot the BlueField Arm core again.

Discovered in version: 24.01

3668925

Description: If a VLAN setup is necessary for a specific interface on the BMC, finish all other network configurations (such as DHCP/STATIC) on the interface before implementing the VLAN setting (because the VLAN inherits all configurations from the existing interface).

Workaround:

1. Initialize the network interface:

   Copy

   Copied!

               
   
               
   ipmitool lan set 1 ipsrc static
   ipmitool lan set 1 ipaddr <ip>
   ipmitool lan set 1 netmask <netmask>
   ipmitool lan set 1 defgw ipaddr <gateway-ip>
           

2. Set the VLAN:

   Copy

   Copied!

               
   
               
   ipmitool lan set 1 vlan id <vlan-id>
           

Discovered in version: 23.10

3534150

Description: The BMC and BlueField utilize a shared IPMB channel for IPMI communication. If multiple requests coincide on this interface, users may encounter command failures with timeout indications.

Workaround: Raise the retry counter for IPMItool requests by using the command ipmitool -R 20 *.

Discovered in version: 23.10

3631199

Description: If Redfish is enabled in the UEFI menu (default), then Secure Boot configuration done from Redfish overrides Secure Boot configuration done from UEFI.

Workaround: Disable Redfish in UEFI menu and update secure boot state.

Discovered in version: 23.10

3654930

Description: If the BlueField BMC firmware has been upgraded from version 2.8.2-x or older to version 23.03 or newer, it is necessary to execute a factory reset of the BlueField BMC.

Workaround: N/A

Discovered in version: 23.03

3637527

Description: The BlueField Redfish BIOS/UEFI supports only UEFI mode for BootSourceOverrideMode. If a user configures the BootSourceOverrideMode to legacy, all override settings are disregarded by the BIOS/UEFI.

Workaround: Set BootSourceOverrideMode to UEFI.

Discovered in version: 23.10

3634649

Description: In the Redfish Systems/Bluefield schema, the LastResetTime attribute does not accurately capture the system reset values.

Workaround: N/A

Discovered in version: 23.09

3634603

Description: When the BlueField operates in NIC mode, the Arm core does not load any OS. In this scenario, any BMC functionality that relies on extracting data from the OS through the IPMB channel will be unavailable or limited. including:

• Firmware inventory schema

• Chassis schema

• Sensors

Workaround: N/A

Discovered in version: 23.10

3609525

Description: Following a reboot of BlueField's BMC, it is necessary to wait 30 seconds to allow for the complete loading of system services before initiating a reboot of BlueField itself.

Workaround: N/A

Discovered in version: 23.09

3590634

Description: When updating the BMC's firmware, it is critical to maintain the system powered on until the update process is finished.

Workaround: N/A

Discovered in version: 23.09

3599824

Description: In NIC mode, the BMC's Redfish chassis schema contains only limited information about BlueField. This is because, in this mode, the OS is not available to supply the necessary information to the BMC.

Workaround: N/A

Discovered in version: 23.09

3605254

Description: Following a system power cycle, both the BlueField and BMC boot independently which may lead to BlueField's UEFI boot process to complete before the BMC's. As a result, when attempting to establish Redfish communication, the BMC may not yet be prepared to respond.

Workaround: Power cycle; Redfish; boot

Discovered in version: 23.09

3388059

Description: When BlueField-2 boots and its services are loaded, there is a possibility that the IPMI over RMCP may become unresponsive due to the default timeout for commands being set to 1 second.

Workaround: Increase the default timeout to 10 seconds when sending IPMI RMCP commands using the -N option. Example command:

            

            
sudo ipmitool -I lanplus -C 17 -N 10 -H <BMC-IP> -U <BMC-User> -P <BMC-Password> mc info
