The following values that are displayed in the Virtual Volume table or in the Root Volumes table might not correspond with the value displayed for this item. This is because the progress of the pool management task is calculated after the progress of each V-VOL displayed in the Virtual Volume table or the Root Volumes table is calculated.

• Pool Management Task - Status
• Pool Management Task - Progress(%)

For details about the tier relocation, see the tier relocation log file.

Capacity

• Used/Total: Displays the used and total pool capacity. If the pool consists of multiple pool-VOLs, the sum of its capacities is displayed in the Total field.

  As for the pool comprised of pool volumes assigned by the accelerated compression-enabled parity groups, the writable capacity might be smaller than the displayed capacity.

• Free + Reserved: Displays the sum of the free capacity and reserved capacity, and displays the formatted pool capacity. If the pool consists of multiple pool-VOLs, the sum of its capacities is displayed in the Total field.

Capacity

Displays information about the V-VOL used capacity.

• Total: Displays the V-VOL capacity.
• Reserved: Displays the reserved page 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 sum of the used V-VOL capacity and the reserved page 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).
• Used: Displays the sum of the mapped capacity and the reserved page capacity.

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

  • Used displays the sum of the mapped capacity and the reserved page capacity that is rounded up on each page.
  • The mapped capacity of DP-VOL includes the capacity of the control information (uses a maximum of 168 MB per 3,145,548 MB).
  • DP-VOL with data direct mapping enabled includes the control information (168 MB is used per 3,145,548 MB) and the capacity for one page.

    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(%): For the entire capacity of V-VOL, this item displays percentages of the sum of the mapped capacity and the reserved capacity.
