Use the information in this section to troubleshoot a single
compute node that cannot ping the optional Flex System Manager management
node in the same chassis on the data network.
Complete the following steps until the problem is solved:
- 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.
- 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.
- 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.
- Make sure that the configuration settings in the node are correct
and that the port is enabled.
- Check Lenovo 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.
- Check Lenovo Support for
any service bulletins that are related to network connectivity.
- Remove the compute node and make sure that the connectors on the
midplane and the node are not damaged.
- (Trained service technician only) Complete the following steps:
- Force the link/duplex speed.
- Check the connectors on the node and the midplane to make sure
that no pins are bent.
