Which two statements accurately describe the Program Product functions available on Hitachi Unified Storage (HUS) systems? (Choose two.)

Question

Options

• ALUN resizing is a basic function in SNM2 and does not require a separate license key.
• BThe Tray Power Saving function does require a separate license key.
• CRestricting access to a HUS Command Device is possible using Account Authentication.
• DHitachi Dynamic Link Manager is used to control the HUS active/active controller feature.

Explanation

Options A and C are the correct answers.

A is correct because LUN resizing in Storage Navigator Modular 2 (SNM2) is a built-in, basic administrative function - no separate Program Product license key is required to use it. It's part of the standard management toolset included with HUS systems.

C is correct because Account Authentication is a licensed Program Product on HUS that specifically enables security controls over who can access a Command Device, allowing administrators to restrict command-level access by user account.

B is wrong because the Tray Power Saving function does not require a separate license key - it is available as a standard feature on HUS systems, making the statement false.

D is wrong because Hitachi Dynamic Link Manager (HDLM) is a host-side multipath I/O software used for path failover and load balancing from the server perspective. It does not control the HUS storage array's active/active controller behavior, which is managed internally by the array firmware.

Memory tip: Think "AC power" - Account authentication and Command Device are the security-related pair. Any time you see HDLM, remember it lives on the host, not the array controller - it manages paths, not controllers.
