Pool Properties table

Item

Description

Pool Name (ID)

Displays the pool name and pool ID.

Pool Type

Displays the pool type.

For a Dynamic Provisioning pool, DP is displayed.

For a Dynamic Tiering pool, DT is displayed.

For an active flash pool, DT(Active Flash) is displayed.

For a pool of the data direct mapping attribute, DP(data direct mapping) is displayed.

For a Thin Image pool, TI is displayed.

Capacity

Displays the pool capacity in the specified unit.

As for the pool using pool-VOLs assigned from the accelerated compression-enabled parity groups, the writable capacity may be smaller than the capacity which is displayed.

User-Defined Threshold (Warning/Depletion)

Displays the user-defined threshold (Warning/Depletion).

Subscription Limit

Displays the subscription limit.

For a Thin Image pool, a hyphen (-) is displayed for Current or Limit.

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.

Encryption

Displays the encryption information about the pool.

  • Enable: Encryption setting of a pool-VOL containing LDEV is enabled.

  • Disable: Encryption setting of a pool-VOL containing LDEV is disabled.

  • Mixed: In the pool, pool-VOLs whose encryption settings are enabled or disabled are intermixed.

This status appears 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(-): The pool is created by external volumes or is being blocked.

Pool VOL with System Area (Name)

Displays LDEV ID and LDEV name of the pool-VOL which includes the system area. If you open this window from the Selected Pools table in the Create Pool window, a hyphen(-) is displayed.

Pool Volumes table

Only the LDEVs assigned to the user are displayed.

Item

Description

LDEV ID

Displays the LDEV identifier, which is the combination of LDKC, CU, and LDEV.

LDEV Name

Displays the LDEV name.

Capacity

Displays the pool volumes capacity in the specified unit. If you open this window from the Selected Pools table in the Create Pool window, the LDEV capacity selected in the Select Pool VOLs window is displayed.

Parity Group ID

Displays the parity group ID.

RAID Level

Displays the tier ID. A hyphen (-) is displayed when selecting the pool for Dynamic Provisioning, or Thin Image.

Tier ID

Displays the tier identifier. A hyphen (-) is displayed when you select a Dynamic Provisioning, or Thin Image pool.

Provisioning Type

Displays the type of the LDEV.

Basic: Internal volume.

External: External volume.

Attribute

Attribute of the volume indicating how the LDEV is being used.

Pool VOL: LDEV of the pool-VOL

Data Direct Mapping: LDEV of the data direct mapping attribute.

Hyphen (-): Volume in which the attribute is not defined.

Cache Mode

For the external volume, this item displays whether the cache mode is enabled. If the LDEV is not an external volume, a hyphen (-) is displayed.

Encryption

Displays the encryption information about the pool.

  • Enable: Encryption setting of a parity group or pool-VOL containing LDEV is enabled.

  • Disable: Encryption setting of a parity group or pool-VOL containing LDEV is disabled.

  • Mixed: Pool-VOLs whose encryption settings are enabled or disabled are intermixed in the pool in which the LDEV is placed.

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(-): External volume.

Accelerated Compression

Displays information about the accelerated compression of the parity group that is created of LDEVs.

Enabled: The accelerated compression of the parity group is enabled.

Disabled: The accelerated compression of the parity group is disabled.

Hyphen (-): accelerated compression is not supported on the parity group.

Resource Group Name (ID)
