The following values that are displayed in the Virtual Volume table or in the Primary Volume table may 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 Primary Volume 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.

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

Tier Management

If Dynamic Tiering is enabled, Auto or Manual of performance monitoring and tier relocation is displayed. If Dynamic Tiering is disabled, a hyphen (-) is displayed.

Monitoring Mode

Displays the monitoring mode that is set for the pool. If the continuous mode is enabled, Continuous Mode is displayed. If the period mode is enabled, Period Mode is displayed. If Dynamic Tiering is disabled, a hyphen (-) is displayed.
