Hi,

We recently upgraded the Infiniband switches (firmware rev 4.8.930+205-0002-05_A) on an Isilon Cluster (OneFS 7.0.1) from 8-port to 24-port switches.  The procedure went smoothly, and indications are that the cluster is now using int-b for data traffic, and int-a for heartbeat/message traffic between cluster nodes.  However, we don't know how to verify this, beyond visual instection of the LED indicators. We have two questions:

1) How do we determine which internal network is being used for primary communication between cluster nodes?  Does it matter?  The docs only state that "int-a must be configured for cluster failover operation to occur"

2) Upon reboot, will primary communication revert back to int-a?

Thanks,

Don Pichette
