8.4 InfiniBand Connection Validation (Layer-2)
Once the cables are connected and you can see green LEDs on the ports, you must
validate the InfiniBand connection.
1.
Log in to the Oracle Big Data Appliance compute node or Exalytics machine.
2.
From the Linux root shell, run the
ibhosts
command to verify if the newly
connected (Exalytics/Oracle Big Data Appliance) machine is visible.
3.
On the Exalytics machine, run the
ibstat
command to see the local ports' status. If
an active Subnet Manager is present, then the ports should be Active.
