Pool Name (ID)

Displays the pool name and pool ID.

RAID Level

Displays the RAID level.

Capacity

Displays information about the pool capacity.

• Total: Total capacity of pool. As for a pool using pool volumes assigned by accelerated compression-enabled parity groups, the writeable capacity might be smaller than the displayed capacity.

• Used: Sum of the mapped capacity and reserved capacity.

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

  • Used displays the sum of the mapped capacity and reserved capacity, which are rounded up on each page.
  • If the emulation type is 3390-A, the mapped capacity of V-VOL includes the capacity of control cylinders (7 Cyl is required per 1,113 Cyl).
  • If the emulation type is 3390-A and the TSE attribute is enabled, the mapped capacity for DP-VOL contains the management area capacity.
  • 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 attribute includes the control information (168 MB is used per 3,145,548 MB) and capacity for one page.
• Used (%): Percentage of the sum of the mapped capacity and the reserved capacity of a pool. The Used (%) field displays the value which is truncated after the decimal point of the actual value.

Drive Type/RPM

Displays the data drive type and RPM. When the volume is the external volume, Drive Type displays External Storage and the value of the external LDEV tier rank.

Encryption

Encryption information:

• Enable: Encryption setting of a parity group in which the LDEV is placed is enabled. Or the virtual volume associated with the pool whose pool-VOLs are enabled of the encryption setting.
• Disable: Encryption setting of a parity group (or a pool) in which the LDEV is placed is disabled. Or the virtual volume associated with the pool whose pool-VOLs are disabled of the encryption setting.
• Mixed: This status is displayed when two or more of the following are specified as pool-VOLs:
  • Volume encryption setting is enabled.
  • Volume encryption setting is disabled.
  • External volume

  Caution: The data encryption is not ensured in the pool that has the Mixed encryption setting. To manage the data encryption securely, use the pool with an encryption setting of Enabled or Disabled.

• - (hyphen): Pool is created by external volumes, or pool is being blocked.

User-Defined Threshold (%)

Displays the pool threshold.

• Warning: Warning threshold is displayed.
• Depletion: Depletion threshold is displayed.

Tier Management

Displays Auto or Manual according to the Tier Management setting when Dynamic Tiering is enabled. Displays Manual for pools other than Dynamic Tiering which are available for monitoring. For other pools, a hyphen (-) is displayed.

Subscription (%)

Displays information about subscription of the pool.

• Current: Percentage of the total V-VOL capacity assigned to the pool and the V-VOL capacity to be created.
• Limit: Percentage of the subscription limit of the pool.

Number of V-VOLs

Displays the number of V-VOLs associated with the pool.

Number of Root VOLs

Displays the number of root volumes of Thin Image pairs associated with the pool.
