Changing coreid of the node due to mismatch

News HP Operations Manager Recommended Links Changing OVcoreid of the node due to mismatch Undefined certificate state  
Policies Default Policy Groups node groups   Humor Etc

HPOM coreid exists both on the node and on the server and sometimes different coreID are generated on the server and on the node.  I found that if primary interface of the server is not used for HPOM communication, installation using almost always produced this problem: agent is installed successfully but certificates are not  not installed so the node cannot communicate with the server.

Other important situation is removal of the node record on the server and then restoring it with opcnode command. 

Probably there are other cases that lead to the same result other then mutihomed servers.

In such case the first step is to compare coreid on the node and on the HPOM server.

On the server you can get node ID using the command

# opcnode -list_id 
List of IDs for node(s): 
Name = ID = bd995f0c-973b-754b-0718-afc25cde7f3f 
Operation successfully completed.

On the node

/opt/OV/bin/ovcoreid -show	bd995f0c-973b-754b-0718-afc25cde7f3f

To set ID on the node you can use command

ovcoreid -set bd995f0c-973b-754b-0718-afc25cde7f3f -force

To set ID on the server use

opcnode -chg_id id=8e475c38-8fb4-754b-0680-946436ccb281

On node the following commands need to be performed

export PATH=$PATH:/opt/OV/bin 
ovcoreid -show # get ID for importing into the server 
/opt/OV/bin/ovcert -importcert -file nti179d.cert -pass xyz1234 
rm nti179d.cert

On the server

opcnode -list_id
 opcnode -chg_id id=8e475c38-8fb4-754b-0680-946436ccb281
to check
opcnode -list_id

Create certificate

opccsacm -issue -name -file /tmp/nti179d.cert -pass xyz1234

scp /tmp/nti179d.cert [email protected]:/
opcragt -status

Restore certificate

ovcert -importcert -file /nti178d,cert -pass xyz1234

[Nov 18, 2010] OVcoreid mismatch

Oct 30, 2006 | IT Resource Center forums

Brian Curley :

We are presently seeing a rash of newly installed Linux nodes which generate the following error:

"The local core ID for node <nodename> is not the same as the core ID for this node stored in the OVO database! (OpC40-1900)"

When I check the what the core ID is in the OVO database, it *IS* the same as that which the node reports in response to a 'ovcoreid -show.' This has occured on several different servers. Sometimes it occurs immediately after the install, other times it occurs days later.

In most cases, doing an 'ovcoreid -set' with the '-force' option (effectively setting the coreid from X to X), followed by a 'opcagt -kill' and 'opcagt -start' has removed the error. However, we have now had the problem occur a second time on a server (after it was corrected by the method above).

Tony Cicone

Are you installing the agents from the command line, or the gui? When I install from the cli, I have to change the coreid manually, after granting the request.

(node)$ ovcert -certreq
(mgmt)$ ovcm -listpending
(mgmt)$ ovcm -grant <request>
(mgmt)$ opcnode -chg_id id=<coreid> node_name=<nodename>

I had the exact same issue and reported it to HP support. These are a copy of the instructions HP support had me perform. I had already done this and kept getting the same results, that being that the core id was the same on the node and in the database:

Change the core ID of the node in OVO db to the local core id of the agent with the opcnode command. On the node you issue ovcoreid ... that give you the coreid then you can issue the following on the Management Server:
/opt/OV/bin/OpC/utils/opcnode -chg_id node_name=Name_of_Managed_Node id='core_id_string'
Then verify the work:
/opt/OV/bin/OpC/utils/opcnode -list_id node_list='Name_of_Managed_Node'
After about 5 months of going around about this issue they sent me a "hotfix"


PROBLEM : coreid mismatch error received, but coreid is identical on node and in database


HP-UX: coreid-hpux.tar (includes two files)

# cksum
3002505180 3391488
# cksum ovoareqsdr
873010857 1286256 ovoareqsdr
This did not work for me, however and I have not re-visted this issue. Hope this helps

Why this guy problem was a closed filewall port, the same symptoms are in case OVcoreid is missing iether on the server or node or they mismatch.

I installed agent in windows server located behind fierwall
i already open port 383 both ways from the fierwall .
After installing the agtent in the node i recive the certificate in the managment server.
I map it to the node and grant it but i got this erroe

Error: 'Node' - Signed certificate could not be delivered to node. Could not send response after 120 retries (OpC40-2063)

i recheck the fierwall and the node everything was working Fine but i tried to resend the certficate and grant it again but still face the same problem .

the telnet from the node to MgmSrv through port 383 is working Ok also the coreid is matching

Node#ovcert -check

OvCoreId set : OK
Private key installed : Failed
Certificate installed : Failed
Certificate valid : Failed
Trusted certificates installed : Failed
Trusted certificates valid : Failed

i used the Attached doucment but it didnt solve my issue


1. Have you checked if communication from management server to node is working?
Run following command from management server:

#bbcutil -ping http://<node name>

If you get the status as "status=eServiceOK" communication is working fine.

If the communication is fine, try to grant the certificate again.

Ramki >

From the management server, try:
a) telnet <agent node>
If it passes, restart agent on the node
b) ovc -kill;ovc -start
c) Now try :
telnet <agent node> 383

Try This:

1.On Management server

opcnode -del_node net_type=NETWORK_IP node_name=Managed_Node

2.On Managed Node

ovcert -list
ovcert -remove [o/p of previous command]
ovcoreid -create -force
ovcert -certreq
