Complete the following steps until the problem is solved.
- If you recently installed, moved, or serviced the computer nodes, reseat the compute nodes in the bays. If the compute nodes were not recently installed, moved, or serviced, perform a virtual reseat through the CMM service command. For more information about the CMM service command, see the "IBM Flex System Chassis Management Module: Command-Line Interface Reference Guide".
- Check the event logs for any events that are related to the compute nodes, and solve them. If an IBM Flex System Manager management node is installed, check the event log on the management node. Otherwise, check the event log on the Chassis Management Module.
