Step 1 If the node table has an entry for the node
• Dump the cache of NMServer, Topod and ILMITopoc. To dump the cache issue a kill -USR1 signal
to the process. Check the dumps in the /usr/user/svplus/log directory and verify if the node is present
in the cache dumps. If the node is present then open a new GUI and check if the node shows in that
GUI.
Step 2 If the node table does not have an entry for the node
• Check ILMItopoc log and verify if it received a 70005 and 70201 (in case persistent topology feature
is turned enabled).
• If you see the trap in the log, verify that ILMITopoc's snmp requests issued after receiving the trap
are successful. If the snmp is not going through verify if the newly added node is ip and snmp
reachable from Cisco MGM.
• If you do not see any of these traps in the ILMITopoc.log, see C.15.1 NTS.
Defect Information—Collect the following information for further analysis:
• Save ILMITopoc.log, topod.log, NMServer.log, nts.*.log
• Collect the dump outputs of ILMITopoc, topod and NMServer. 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—Add the node again to the network by first deleting it and then adding
it again.
