You are implementing a Hitachi Unified Storage File Module cluster with a single SMU. How do you run the smu-config script?

The correct answer is D. Connect a serial null-modem cable and login as root. Running smu-config requires a serial null-modem cable because the SMU's network interface has not yet been configured - Ethernet connectivity is unavailable until the script completes, making Options A and C impossible at this stage.

Explanation

Running smu-config requires a serial null-modem cable because the SMU's network interface has not yet been configured - Ethernet connectivity is unavailable until the script completes, making Options A and C impossible at this stage. The script must be run as root (not supervisor), because it performs low-level system configuration that requires full administrative privileges; "supervisor" is not the appropriate account for this task, eliminating Options B and A. Options B and C fail on one criterion each - B uses the correct cable but the wrong login, C uses the correct login level concept but the wrong connection method.

Memory tip: Think "serial before Ethernet" - you can't configure the network over the network, so the null-modem cable comes first, and system-level scripts like smu-config always need root, not a named admin role.
