6. Check http://www.ibm.com/supportportal/ for any service bulletins that are
related to network connectivity.
7. Remove the management node and make sure that the connectors on the
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 nodes and the midplane to make sure that no
pins are bent.
c. Replace the I/O expansion card in the management node.
d.
Replace the system-board assembly in the management node.
Multiple nodes cannot ping the management node in the same chassis or a
different chassis:
Use the information in this section to troubleshoot multiple nodes that cannot ping
the IBM Flex System Manager management node in the same chassis or a different
chassis on the data network.
Action
Complete the following steps until the problem is solved:
1. Follow the steps in “Multiple nodes cannot ping the management node in the
same chassis” on page 469.
2. Follow the steps in “Multiple nodes cannot ping the management node in a
different chassis” on page 470.
Cannot ping the IBM Flex System Manager management node on
the management 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 management
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 IBM Flex System Manager management node in the same chassis
on the management 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 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.
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 473. Make
