The following issues are noted for RDMA:

• ibacm service disabled by default

  The ibacm service is disabled by default immediately after installation, which means the ibacm service does not automatically start after a reboot. This behavior is expected. Note that requirements for using the ibacm service are application-specific. If your application requires this service, you may need to enable the service so that it starts after a reboot:

  # systemctl enable ibacm

• Error: some other host already uses address xxx.xxx.xxx.xxx

  The following error message might be triggered in certain instances:

  Error, some other host already uses address xxx.xxx.xxx.xxx
                       

  This issue is typically triggered if active-bonding is enabled and you then run the ifup ib-interface command.

  You can ignore this message, as the InfiniBand interface is brought up successfully. (Bug ID 28097516)
