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.

    The Used value displayed might be larger than the Total value displayed of due to following reasons:

    • Used displays the sum of the mapped capacity and the reserved capacity that is rounded up on each page.

  • 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.
