Cannot ping the Flex System Manager management node on the data network
Use the information in this section to troubleshoot the compute node when one or more compute nodes
cannot ping the management node on the data network.
Single node cannot ping the management node in the same chassis
Use the information in this section to troubleshoot a single compute node that cannot ping the Flex System
Manager management node in the same chassis on the data network.
Action
Complete the following steps until the problem is solved:
1. Make sure that the management node is powered on and is not hung, by logging in to the management
node. If you are unable to log in from the management network, attempt to log in from the data network.
If the management node is powered on and hung, perform a virtual reseat of the management node from
the CMM.
2. Make sure that the I/O module is powered on and is not hung, by pinging the I/O module from the
management node. If the I/O module is powered on and hung, reset the I/O module. Make sure that the
correct ports are enabled for the node on the I/O module.
3. Make sure that the compute node is the only one in the chassis that the management node cannot ping.
If it is not, follow the steps in
on page 860.
4. Make sure that the configuration settings in the node are correct and that the port is enabled.
5. Check

view the release notes for a firmware update to determine the issues that are addressed by the update.
6. Check http://www.lenovo.com/support
7. Remove the compute node and make sure that the connectors on the chassis midplane and the node
are not damaged.
8. (Trained service technician only) Complete the following steps:
a. Force the link/duplex speed.
b. Check the connectors on the node and the chassis midplane to make sure that no pins are bent.
c. Replace the base assembly in the compute node.
Single node cannot ping the management node in a different chassis
Use the information in this section to troubleshoot a single compute node that cannot ping the Flex System
Manager management node in a different chassis on the data network.
Action
Complete the following steps until the problem is solved:
1. Make sure that the management node is powered on and is not hung, by logging in to the management
node. If you are unable to log in from the management network, attempt to log in from the data network.
If the management node is powered on and hung, perform a virtual reseat of the management node from
the CMM.
2. Make sure that the I/O module is powered on and is not hung, by pinging the I/O module from the
management node. If the I/O module is powered on and hung, reset the I/O module. Make sure that the
correct ports are enabled for the node on the I/O module.
3. Make sure that the compute node is the only one in the chassis that the management node cannot ping.
If it is not, follow the steps in
on page 860.
