7.6 Checking Network Health

After establishing InfiniBand network connectivity, you can verify the status of the basic InfiniBand network connectivity with rds-ping, rds-info -l by using the ibstat command on the Exalytics machine.

The ibstat command displays the basic status, as in the following example:

# ibstat
