The 10 GigE interfaces on one or more nodes have experienced network connectivity issues.
Administrator action
Determine whether the issue is related to the cable or the node. Perform the following steps in the order listed. If the issue
resolves after a step, there is no need to complete the subsequent steps.
1. Verify the following connections:
●
All of the cables in the rack and in adjacent racks are connected securely to the node and neither the cable nor the
connector is damaged.
●
The cable is rated for the appropriate Ethernet speed.
●
The switch port speed is set to the same or higher speed as the Ethernet cable.
●
The switch port is set to the Full Duplex setting.
2. If the cable is connected securely, plug the cable into a different node that has a network port functioning at full speed and
that has an identical network configuration. When you plug the cable into the other node, leave the other end of the cable
plugged into the same switch port.
●
If the issue persists after plugging the cable into a different node, replace the cable.
●
If the issue persists after replacing the cable, move the cable to another port on the switch.
●
If the issue persists after moving the cable to another port on the switch, review the switch logs and consult your switch
user manual.
If the event persists, gather logs, and then contact Technical Support for additional troubleshooting. For instructions on how to
gather cluster logs, see

Multiple internal network issues were detected.
Administrator action
Perform the following steps in the order listed. If the issue resolves after a step, there is no need to complete the subsequent
steps.
1. If internal network issues are not ongoing and this issue is not a recurring problem, attempt the following steps:
●
Make sure that all InfiniBand (IB) cables in the rack and in adjacent racks are connected securely to the node and are
undamaged.
●
Make sure there are no kinks or sharp bends in the cables. InfiniBand (IB) cables have an approximate maximum bend
radius of 1.5 inches (38mm).
2. If internal network issues are ongoing but do not continually recur, attempt the following steps.
●
Determine whether the issue is related to the cable or the node. Plug the affected cable into another node that has a
functioning network port and an identical network configuration. Be sure to plug the cable into the same network port on
the different node.
●
If the issue persists after plugging the cable into a different node, replace the cable.
●
If the issue persists after replacing the cable, move the cable to another port on the switch.
●
Confirm that multiple clusters are not connected to the same IB switch. This configuration is unsupported and can cause
this issue. Each cluster must be connected to a dedicated IB switch.
If the event persists, gather logs, and then contact Technical Support for additional troubleshooting. For instructions on how to
gather cluster logs, see
