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 “Multiple nodes cannot ping the management node in the same
chassis” on page 623.
4. Make sure that the IP configuration settings on the node are correct and that the port is enabled.
5. Check http://www.lenovo.com/support for any firmware updates that might apply to this issue. You can
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 for any service bulletins that are related to network connectivity.
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.
Multiple nodes cannot ping the management node in the same chassis
Use the information in this section to troubleshoot multiple nodes that cannot ping the Flex System Manager
management node in the same chassis on the data network.
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 management network port (eth1) is enabled in the management node. Make sure
that the port configuration settings are correct for the data network.
4. Make sure that the configuration settings for each node are correct and that the data network ports
are enabled.
5. Make sure that the configuration settings in the I/O module are correct and that the applicable ports
are enabled for your compute nodes and the management node on the I/O module. If the problem
remains, complete the following steps:
a. Restart the I/O module.
b. Check http://www.lenovo.com/support for any firmware updates that might apply to this issue.
You can view the release notes for a firmware update to determine the issues that are addressed
by the update.
