The following issues are noted for RDMA:

• ibacm service is disabled by default

  The ibacm service is disabled by default immediately after installation. This means that the ibacm service does not automatically start after a reboot. This is intended behavior. Requirements to use the ibacm service are application-specific. If your application requires this service, you may need to enable the service to start after reboot:

  # systemctl enable ibacm

  (Bug ID 28074471)

• 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 when active-bonding is enabled, and you run the ifup ib-interface command.

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