The link status of the identified InfiniBand interface is changing rapidly and repeatedly.
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 above steps do not resolve the issue, gather logs, and then contact Technical Support for additional troubleshooting. For
instructions on how to gather cluster logs, see
