Complete the following steps until the problem is solved:
- If more than one node is having this problem, reset the CMM, or fail over the CMM to the standby CMM if two CMMs are installed.
- Check the event logs and any status indicators for the node for possible additional information about the problem. Follow the troubleshooting instructions in the information center or Installation and Service Guide for the node that is reporting the event. Check the documentation for any applications that are running for application-specific troubleshooting instructions.
- Perform a hard restart of the node system-management processor.
- Perform a virtual reseat of the node. Attention: A virtual reseat shuts down power to the node. Check the interfaces of applications that are running to make sure that the node can be shut down safely.
