Use the information in this section to troubleshoot a single Flex System x222 Compute Node that
cannot ping the Flex System Manager management
node in the same chassis on the management 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 CMM is
powered on and is not hung, by pinging the CMM from
the management node. If the CMM is
powered on and hung, reset the CMM.
Make sure that the IMM, the management node, and CMM are
all on the same subnet.
- Make sure that the upper and lower compute nodes in the Flex System x222 Compute Node are
the only ones in the chassis that the management node cannot ping.
If they are not, follow the steps in Multiple nodes cannot ping the management node in the same chassis.
Make sure that the compute nodes appear on the chassis map (it might
not be fully discovered by the management node software).
- Make sure that the system-management processor in each compute
node has a valid IP address by checking the chassis map of the remote
chassis.
Note: If the CMM recently
lost connection to the DCHP server, you must reset the IMM by using
the CMM interface
so that a new IP address can be acquired.
- In the CMM user
interface, click Chassis Management > Component IP Configuration and
make sure that the IP addresses that are listed are the same as the
IP addresses that are displayed in the Setup utility. If the IP addresses
listed are not the same, configure the IMM network settings correctly.
- Check the Lenovo Support Portal 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 the Lenovo Support Portal for
any service bulletins that are related to network connectivity.
- Remove the compute node and make sure that the connectors on the
chassis 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 chassis midplane to make
sure that no pins are bent.
- Replace the system-board assembly (see Removing a system-board assembly and Installing a system-board assembly).
