The ovcoreid command is used to display existing OvCoreId values and, in addition, create and set new OvCoreId values on the local node.
|
|
NOTE: Changing the OvCoreId of a system is analogous to giving the system a new identity and is an action that should only be executed if the consequences are fully understood. Changing the OvCoreId of a system requires a number of significant changes including the need for a new certificate, and having to do appropriate reconfiguration of the OpenView server(s).
Parameters and options:
Displays the current OvCoreId of the system (configuration setting CORE_ID in namespace [sec.core]). This is the default if no parameters are specified. If the OvCoreId you want to show belongs to an OpenView Resource Group, use the -ovrg option to specify the name of the Resource Group. If an OV Resource Group is specified, the corresponding configuration settings will be read or modified as well.
If you specify a non-existent OV Resource Group, ovcoreid displays the local OvCoreId.
Generates a new OvCoreId. If a CORE_ID value already exists, the existing OvCoreId is only overridden when -force is specified. If the OvCoreId you want to show belongs to an OpenView Resource Group, use the -ovrg option to specify the name of the Resource Group. If an OV Resource Group is specified, the corresponding configuration settings will be read or modified as well.
If you specify a non-existent OV Resource Group, ovcoreid displays an error.
Sets a specific OvCoreId. The -force option must be used if an OvCoreId value has already been set. If the OvCoreId you want to show belongs to an OpenView resource group, use the -ovrg option to specify the name of the resource group. If an OV Resource Group is specified, the corresponding configuration settings will be read or modified as well.
Returns the version of the tool (the component version).
Display all available command options.
The following exit values are returned:
Corresponding error messages are written to stderror.
The following examples show you how to use the ovcoreid command:
On list node CoreID on the server:
# opcnode -list_id node_name=sp78d.dmz2.firma.com
List of IDs for node(s):
Name = sp78d.dmz2.firma.com ID = bd995f0c-973b-754b-0718-afc25cde7f3f
Operation successfully completed.
To list node coreID on the node with agent installed
/opt/OV/bin/ovcoreid -show
bd995f0c-973b-754b-0718-afc25cde7f3f
To set ID on the server use
opcnode -chg_id node_name=sp79d.dmz2.firma.com id=8e475c38-8fb4-754b-0680-946436ccb281
To set ID on the node you can use command
ovcoreid -set bd995f0c-973b-754b-0718-afc25cde7f3f -force
Display the OvCoreId for the local node:
ovcoreid -show
To create and set a new OvCoreId on the local node:
ovcoreid -create
To set the specified OvCoreId on the local node:
ovcoreid -set <OvCoreId>
To create a certificate file on the server
opccsacm -issue -name sp79d.dmz2.firma.com -file /tmp/sp79d.cert -pass xyz1234
To copy it to the node:
scp /tmp/sp79d.cert [email protected]:/
To import certificate from a file on the node
export PATH=$PATH:/opt/OV/bin
/opt/OV/bin/ovcert -importcert -file sp79d.cert -pass xyz1234
opcnode -list_id node_name=sp79d.dmz2.firma.com opcnode -chg_id node_name=sp79d.dmz2.firma.com id=8e475c38-8fb4-754b-0680-946436ccb281 to check opcnode -list_id node_name=sp79d.dmz2.firma.com
Create certificate
opcragt -status sp79d.dmz2.firma.com
Restore certificate
ovcert -importcert -file /sp78d.cert -pass xyz1234
See also Undefined certificate state
To install the certificates manually, follow these steps:
a. Set the installation type to MANUAL by entering the following command:
$ ovconfchg -ns sec.cm.client -set "CERTIFICATE_DEPLOYMENT_TYPE" "MANUAL"
b. Check if ovcoreid is set by entering the following command:
$ ovcoreid -show
If ovcoreid is not set, the following message will be displayed:
INFO: No OvCoreId is set.
c. If ovcoreid is not set, create the ovcoreid by entering the following
command:
$ ovcoreid -create
An error message "ERROR: No input stream" will be displayed that can be ignored.
d. To check whether the settings are correct, run ovconfget command
For example,
[sec.cm.client]
CERTIFICATE_DEPLOYMENT_TYPE=MANUAL
[sec.core]
CORE_ID=fc200278-8f86-751f-0e73-cbd79be7b384
[sec.core.auth]
MANAGER=my.mgmt.srvr.com
MANAGER_ID=970qedsd-4212-7564-1234-qwn6kuu2d07
e. Log in to the Operations Manager Server on UNIX as a root user and
add the "coreid" of Unix managed node manually to the Operations
Manager Server by entering the following command:
#/opt/OV/bin/OpC/utils/opcnode -chg_id node_name=node id=coreid_of_the_node
For example,
#/opt/OV/bin/OpC/utils/opcnode -chg_id node_name=
test.in.hp.com id= fc200278-8f899-701f-0e73-cbd79be7b384
f. Create a signed certificate and the corresponding private key for a specific managed node manually using the opccsacm command line tool. You must provide a password to encrypt the created data.
