LUNs tab

This tab provides information about the LU paths that correspond to the LDEV assigned to the logged-in user.

Item	Description
Port ID	Identifier of the port.
LUN ID	Icons and identifiers of the logical unit. Clicking a LUN ID opens the LUN Properties window.

Pool Name (ID)	Displays the pool name and pool ID. If the logical volume is not the volume other than V-VOL, a hyphen (-) is displayed.
Capacity	Total: Displays the logical volume capacity. Reserved: Displays the reserved capacity of the V-VOL. The displayed value of Reserved might be larger than the displayed value of Total due to following reasons: Reserved displays the reserved capacity that is rounded up on each page. The mapped capacity of V-VOL for Dynamic Provisioning includes the capacity of control information (168 MB is required per 3,145,548 MB). If used capacity is referenced during I/O or copy processing by software such as ShadowImage or Universal Replicator, the used capacity displayed might be different from the actual capacity even if the full allocation is enabled on the V-VOL. This is caused by a gap between the times that information is gathered about the mapped capacity and the reserved capacity. Used: Displays the sum of the mapped capacity and the reserved capacity.

Used Capacity	Tier1: Displays the used capacity of tier 1. If the logical volume is not the volume other than V-VOL for Dynamic Tiering or active flash, a hyphen (-) is displayed. Tier2: Displays the used capacity of tier 2. If the logical volume is not the volume other than V-VOL for Dynamic Tiering or active flash, or if tier 2 does not exist, a hyphen (-) is displayed. Tier3: Displays the used capacity of tier 3. If the logical volume is not the volume other than V-VOL for Dynamic Tiering or active flash, or if tier 3 does not exist, a hyphen (-) is displayed. The reserved capacity is not included in the used capacity for each tier of the V-VOL. Therefore, the Used value in the Capacity column may not correspond with the Used Capacity value.
