What are two characteristics of the Modular Volume Migration feature? (Choose two.)

Question

Options

• AIt requires Copy-on-Write to be enabled on the array.
• BIt can be managed by RAID Manager/CCI.
• CIt formats the source LU when migration is complete.
• DIt can be managed by Storage Navigator Modular 2 GUI.

Explanation

Modular Volume Migration (on Hitachi Modular storage systems) can be managed by both RAID Manager/CCI (B) and Storage Navigator Modular 2 GUI (D). These two tools represent the dual management paths - command-line and graphical - for controlling migration jobs, making them the correct pair of characteristics.

Why the distractors are wrong:

• A is incorrect because Copy-on-Write is a snapshot/thin-provisioning mechanism, not a prerequisite for volume migration.
• C is incorrect because the source LU is not formatted upon migration completion - data on the source is preserved, allowing for rollback or verification before any cleanup.

Memory tip: Think "two ways to manage = two correct answers." Hitachi modular features almost always expose both a GUI path (Storage Navigator Modular 2) and a scripting/CLI path (RAID Manager/CCI) - if a question asks about management interfaces, both options together are typically correct. Anything about format, delete, or Copy-on-Write for a migration feature should be a red flag.
