A compute node in the chassis cannot ping the CMM on management network
Complete the following steps until the problem is solved:
1. Make sure that the CMM is powered on and the applicable ports are enabled on the CMM.
2. Make sure that the compute node BMC (Lenovo XClarity Controller) has acquired an IP address from the
CMM by using the Setup utility on the node.
Note:
If the CMM recently lost connection to the DCHP server, you must reset the BMC by using the
CMM interface so that a new IP address can be acquired.
3. In the CMM user interface, click
Chassis Management
➙
Component IP Configuration
and make
sure that the IP address that is listed is the same as the IP address that is displayed in the Setup utility. If
it is not the same IP address, configure the BMC network settings correctly or reset the BMC to
automatically acquire a new IP address.
4. Check http://datacentersupport.lenovo.com for any firmware updates that might apply to this problem.
You can view the release notes for a firmware update to determine the issues that the update addresses.
5. Remove the compute node from the chassis and check the connectors on the back of the node for bent
pins. If the pins are bent, contact Lenovo Support.
6. Install the compute node in another node bay to determine whether the problem remains. If the problem
remains, make sure that the compute node is connected to a port that has been enabled and that the
vLAN settings allow that port to connect to the network.
7. Check http://datacentersupport.lenovo.com for any tech tips (service bulletins) that are related to
network connectivity.
8. (Trained service technician only) Complete the following steps:
a. Force the link/duplex speed.
b. Check the connectors on the I/O module to make sure that no pins are bent.
c. Check the connectors on the chassis midplane to make sure that no pins are bent.
d. Remove the CMM and install a working CMM in the same bay.
e. If the problem is solved, replace the CMM that you removed.
Multiple compute nodes in the chassis cannot ping the CMM on management network
Complete the following steps until the problem is solved:
1. Make sure that the CMM is powered on and the applicable ports are enabled on the CMM. If the CMM is
hung, reset the CMM.
2. Reset the CMM.
3. Check for firmware updates for the CMM.
4. Reset the CMM to factory defaults and attempt to discover the nodes again. Allow enough time for each
BMC to acquire a network address.
5. Replace the CMM.
6. Make sure that the compute node BMC has acquired an IP address from the CMM by using the Setup
utility on the node.
Note:
If the CMM recently lost connection to the DCHP server, you must reset the BMC by using the
CMM interface so that a new IP address can be acquired.
