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.

• Used: For a pool comprised of pool volumes assigned to accelerated compression-disabled parity groups, the sum of the mapped capacity and reserved capacity.

  For a pool comprised of pool volumes assigned to accelerated compression-enabled parity groups, the pool used capacity is displayed.

  For a pool comprised of pool volumes assigned to accelerated compression-disabled parity groups, 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.
  • 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 (%): For a pool comprised of pool volumes assigned to accelerated compression-disabled parity groups, the percentage of the sum of the mapped capacity and the reserved capacity of a pool. For a pool comprised of pool volumes assigned toaccelerated compression-enabled parity groups, the pool used capacity percentages against the pool capacity is displayed.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.

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.
