You plan to use Storage Navigator Modular 2 (SNM2) to perform a non-disruptive upgrade of the firmware on a Hitachi Unified Storage (HUS) system. What are two requirements for this process? (Choose…

Question

Options

• AThe HUS must have a Device Manager Agent installed and running.
• BThere must be no hardware faults or missing components on the HUS.
• CYou must have a working LAN connection between the SNM2 server and the HUS.
• DAll hosts must be connected to the HUS using HDLM or similar multi-pathing software.

Explanation

B and C are the correct answers.

SNM2 communicates with the HUS over a standard LAN/IP connection (Option C), making that network link a hard requirement - without it, SNM2 simply cannot reach the array to push the firmware. Before initiating a non-disruptive upgrade, the HUS must also be in a fully healthy state with no hardware faults or missing components (Option B), because an already-degraded system cannot safely absorb a rolling firmware update without risking data availability.

Why A is wrong: A Device Manager Agent is a component used with Hitachi Device Manager (HDvM), a separate management product - it is not required for SNM2 to communicate with or upgrade a HUS. Why D is wrong: HDLM or multi-pathing on hosts is a best practice for host-side resilience, but it is not a prerequisite that SNM2 checks or enforces before performing the firmware upgrade process itself.

Memory tip: Think "Healthy + Reachable" - the HUS must be Healthy (no faults, no missing parts) and Reachable (LAN connection to SNM2). If either condition fails, you don't have a non-disruptive upgrade - you have a risk.
