  • 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 appears if the pool corresponds with one of the following:

  • Data Retention Utility is not installed.
  • Pool type is other than DP or DT.

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. And at the same instant, the access attribute of the DP-VOL is changed to the Protect attribute.

A hyphen appears if the pool corresponds with one of the following:

  • Data Retention Utility is not installed.
  • Pool type is other than DP or DT.

Tier Management

If Dynamic Tiering is enabled, Auto or Manual for performance monitoring and tier relocation is displayed. If Dynamic Tiering is 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.

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 Tiering is 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

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