Explanation
IB ports are not operational.
User Response
An offline port can have many causes and so it is necessary to check them all.
Start with the easiest and least intrusive possibility.
- Reset the IB port with CLI command.
- If the IB port is connected to a switch, double-check the switch configuration for issues.
- Reseat the IB cable on both the IB side and the HBA/switch side.
- Run a temporary second IB cable to replace the current one to check for a cable fault.
- If the system is in production, schedule a maintenance downtime before continuing to
the next step. Other ports will be affected.
- Reset the IB interface adapter; reset the node; reboot the system.
