Topology Problems
Step 3 If it is a MGX2 node and If persistent topology is enabled on the switch gateway and some nodes in a
peer group are not getting discovered, verify that persistent topology is enabled on the gateway in the
peer group using the CLI dsptopogw. If the gateway flag is enabled then verify in the node is part of the
list of nodes on the gateway using the CLI command dsptopondlist
Defect Information—Collect the following information for further analysis:
• Save topod.log, ILMITopoc.log
• Collect the data in node_info table.
• Collect the output of dspndparms, dspsnmp, dspipif on the MGX node.
Possible alternative workaround—None
C.4.2.2 Node Name Is Incorrect in Database
The node name of the standalone MGX node is incorrect.
Step 1 If the node table has the name correct
• Dump the cache of topod and ILMITopoc. This can be done by issuing a kill -USR1 to the process.
From the dump verify which process has the information incorrectly. If the information is correct in
all these processes then open a new GUI and verify if the problem still exists.
Step 2 If the node table does not have the name correctly
• Check the ILMITopoc.log file to see from which node it got the wrong information.
• Do an snmpget -c <community> <ipAddress> 1.3.6.1.2.1.1.5. Verify that the name received as a
response is correct. If it is not then verify the name on the switch.
Defect Information—Collect the following information for further analysis:
• Save the ILMITopoc.log and topod.log
• Collect the dump outputs of ILMITopoc, topod. The dump can be captured by issuing a kill -USR1
signal to the process.
• Collect the output of the switch CLI, selnd and dbnds.
Possible alternative workaround—None
C.4.2.3 Node IP Is Incorrect in Database
The ip Address of a node is not shown correctly.
Step 1 If the node table has the ipAddress correct
ßDump the cache of topod and ILMITopoc. This can be done by issuing a kill -USR1 to the process.
From the dump verify which process has the information incorrectly. If the information is correct in all
these processes then open a new GUI and verify if the problem still exists.
