Question 37

A system administrator has configured a system using the Initial Configuration wizard. After completing the wizard, the administrator discovers that an incorrect IP address has been assigned to the Unity system.
How can the IP address be changed?

A. The IP address cannot be changed once it has been configured
B. Through the Service interface using the ifconfig command
C. In the Unisphere Settings menu
D. The IP address can only be changed using the UEMCLI

Correct Answer:D
The svc_initial_config UEMCLI command sets up initial system configuration. It configures a management IP address when the Connection Utility (CU) is not available on the network. If an address is set, this command can also change the management IPv4 and IPv6 configuration mode. It attempts to configure the system with the given friendly name and/or network parameters.
Note: The Unisphere CLI (UEMCLI) is a tool that provides us with the CLI access to perform the same actions as one would on the Unisphere web interface.
