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

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

4064373

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: 24.04

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: 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

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
