ports. For direct access to the node, connect to the serial port.
LEDs
Do not rely on LEDs to determine the health of a node or node component. If any
hardware component is in an error state, identify and troubleshoot the error through
OneFS events and alerts. The behavior of the lights can change after a firmware update
and might not accurately reflect the health of a node.
Connect the internal cluster network
The InfiniBand cable connects the node to the cluster's internal network so the node can
communicate with the other nodes in the cluster.
Procedure
1. With an InfiniBand cable, connect the int-a port to the network switch for the Internal
A network.
