A service provider is installing a Unity storage system for an end-user. The end-user is concerned about network security and will not allow the service provider access to the network.
How can the service provider set a static IP address for the Unity storage system management interface?

• A. Use the embedded InitCLI tool
• B. Connect directly to the service ports and configure the networking through UEMCLI
• C. Use an IPMI serial over LAN connection
• D. Use the Connection Utility to create a configuration file

Answer: B

Explanation:
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.
