This section explains the procedure for adding or modifying destinations for network device connection.
When there is no description, the following operations are performed by an infrastructure administrator.
Notify your infrastructure administrator about the addition or modification of the destination for network device connection. (Network device administrator)
Create network configuration information (XML definition) using the acquired network device information.
Confirm there are no differences besides the link information (under Links tag) regarding the added or modified destinations for connection, by comparing the network configuration information of network devices registered in Resource Orchestrator and the network configuration information created in step 2.
If there is any difference, check with the system administrator that network device configurations have not been modified, and change the network configuration information if necessary.
The network configuration information of network devices registered in Resource Orchestrator can be obtained using the rcxadm netconfig export command.
Modify the network device by setting the confirmed network configuration information as the input information.
Use the rcxadm netconfig import command to modify network devices.
Confirm from the ROR console that the network device information has changed, and the status is normal.
