Pool Name (ID)

Displays the pool name and pool ID.

RAID Level

Displays the RAID level. If multiple RAID levels exist in a pool, this field indicates that RAID levels are mixed. If all pool-VOLs are external volumes, a hyphen (-) is displayed.

Capacity

Displays the pool capacity.

(Open systems) For a pool containing pool volumes assigned by accelerated compression-enabled parity groups, the writable capacity may be smaller than the displayed capacity.

Pool Type

Displays the pool type.

For a Dynamic Provisioning pool, DP is displayed.

For a Dynamic Tiering pool, DT is displayed.

For a pool being used for active flash, DT(Active Flash) is displayed.

For a pool with data direct mapping enabled, DP (data direct mapping) is displayed.

For a Thin Image pool, TI is displayed.

Drive Type/RPM

Displays the data drive type and RPM. If multiple drive types or RPMs exist in a pool, this field indicates that drive types or RPMs are mixed. When the volume is the external volume, Drive Type displays External Storage and the value of the external LDEV tier rank.

Encryption

Encryption: The encryption information of the pool.

• Enabled: Pool which is created by pool-VOLs whose encryption settings are enabled.
• Disable: Pool which is created by pool-VOLs whose encryption settings are disabled.
• 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.

User-Defined Threshold (%)

Displays the pool threshold.

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

For a Thin Image pool, a hyphen (-) is displayed for Depletion.

Suspend TI pairs when depletion threshold is exceeded

Displays the setting for outputting SIM code 62Exxx when the pool used capacity exceeds the depletion threshold.

• Yes: When the pool used capacity exceeds the depletion threshold, SIM code 62Exxx is output.
• No: When the pool used capacity exceeds the depletion threshold, SIM code 62Exxx is not output.

Subscription Limit (%)

Displays the subscription limit.

For Thin Image pool, a hyphen (-) is displayed.

Protect V-VOLs when I/O fails to Blocked Pool VOL

Displays whether the protect function for DP-VOL is being enabled or disabled. If the setting is enabled, when the pool-VOL is blocked, DP-VOL is protected from reading and writing requests. And at the same instant, the access attribute of the DP-VOL is changed to the Protect attribute.

A hyphen is displayed if the pool corresponds with one of the following:

• Data Retention Utility is not installed.

Protect V-VOLs when I/O fails to Full Pool

Displays whether the protect function for DP-VOL is being enabled or disabled. If the setting is enabled when the pool usage reaches the full size, DP-VOL is protected from reading and writing requests. At the same instant, the access attribute of the DP-VOL is changed to the Protect attribute.

A hyphen is displayed under these conditions:

• Data Retention Utility is not installed.

Number of Pool VOLs

Displays the number of pool-VOLs.

Tier Management

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

Cycle Time

Displays the cycle of performance monitoring and tier relocation. If Dynamic Tiering is disabled, a hyphen (-) is displayed.

Monitoring Period

Displays the time zone of performance monitoring when 24 Hours is selected as the Cycle Time. If Dynamic Tiering is disabled, a hyphen (-) is displayed.

Monitoring Mode

If the continuous mode is enabled, Continuous Mode is displayed. If the period mode is enabled, Period Mode is displayed.

Relocation speed

Displays the page relocation speed: 1(Slowest), 2(Slower), 3(Standard), 4(Faster), or 5(Fastest). If Dynamic Tierings disabled, a hyphen (-) is displayed.

Buffer Space for New page assignment (%)

Displays the information of the buffer space for new page assignment to each tier.

Tier 1: If you make the Dynamic Tiering function available, the buffer space for new page assignment to tier 1 is displayed. If you make the Dynamic Tiering function unavailable, a hyphen (-) is displayed.

Tier 2: If you make the Dynamic Tiering function available, and tier 2 exists, the buffer space for new page assignment to tier 2 is displayed. If you make the Dynamic Tiering function unavailable, or tier 2 does not exist, a hyphen (-) is displayed.

Tier 3: If you make the Dynamic Tiering function available, and tier 3 exists, the buffer space for new page assignment to tier 3 is displayed. If you make the Dynamic Tiering function unavailable, or tier 3 does not exist, a hyphen (-) is displayed.

Buffer Space for Tier relocation (%)

Displays the information of the buffer space for tier relocation to each tier.

Tier 1: If you make the Dynamic Tiering function available, the buffer space for tier relocation to tier 1 is displayed. If you make the Dynamic Tiering function unavailable, a hyphen (-) is displayed.

Tier 2: If you make the Dynamic Tiering function available, and tier 2 exists, the buffer space for tier relocation to tier 2 is displayed. If you make the Dynamic Tiering function unavailable, or tier 2 does not exist, a hyphen (-) is displayed.

Tier 3: If you make the Dynamic Tiering function available, and tier 3 exists, the buffer space for tier relocation to tier 3 is displayed. If you make the Dynamic Tiering function unavailable, or tier 3 does not exist, a hyphen (-) is displayed.

Deduplication

(Open systems)

If the pool type is HDP, this item displays Available or Not Available for the deduplication setting. If the pool type is other than HDP, a hyphen (-) is displayed.

Detail
