Explanation

Parity Groups (A) and Logical Groups (C) represent the two-step physical-to-logical workflow for storage allocation in Hitachi Device Manager. Parity Groups are the RAID-based physical disk sets where you create LDEVs (Logical Devices) - this is where raw capacity originates. Logical Groups is where those LDEVs are mapped and presented to host groups with LUN assignments, completing the allocation to the host.

Admin Groups (B) controls user access and role-based permissions within the Device Manager application itself - it has nothing to do with provisioning storage. Mobility Groups (D) is used for data migration and storage tiering operations, not for initial host allocation.

Memory tip: Think of it as "P → L → Host" - Physical parity groups produce the storage, Logical groups deliver it to the host. If the letter isn't P or L, it's not part of provisioning.
