Because the ibacm service starts at boot time, but the rdma service does not start, an error indicating the ibacm service failed to start is displayed when the system boots. This error is also logged in /var/log/ibacm.log immediately after the system boots.

The workaround for this issue is to manually start the ibacm service after every boot by running the service ibacm start command.
