While installing a new Hitachi Unified Storage (HUS) system, your customer wants to manage the array using a fixed Public IP address. How can this be accomplished?

Question

Options

• AUse the Web Tool on the Public LAN port for each controller to reconfigure the IP address.
• BUse SNM2 to connect to the Maintenance LAN port on either controller to set the IP address.
• CAsk the customer to set a static address on the DHCP Server and plug in the Public LAN.
• DSet the IP address using the LCD displays of each controller on the HUS.

• A
  9% (3)
• B
  85% (28)
• C
  3% (1)
• D
  3% (1)

Explanation

Option B is correct because SNM2 (Storage Navigator Modular 2) is Hitachi's designated management tool for initial HUS configuration. Connecting via the Maintenance LAN port - which has a known default IP for out-of-box access - lets you configure the Public LAN's fixed IP address before it's reachable. Either controller's Maintenance LAN port works since they share configuration.

Why the others are wrong:

• A - The Web Tool on the Public LAN port is unreachable until that IP is already configured, creating a chicken-and-egg problem.
• C - A DHCP static reservation is a workaround, not a proper HUS configuration method; the correct approach sets the IP directly in the array via SNM2.
• D - HUS LCD panels display basic status only; they do not expose network configuration options.

Memory tip: Think "Maintenance LAN → Manage with SNM2" - you always go through the dedicated Maintenance port first to configure everything else, just like you'd use a console cable on a switch before its management IP is set.
