Select Pool VOLs window

Use this window to add pool-VOLs to a pool. Only the LDEVs assigned to the logged-on user are available.

Available 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-VOL capacity.

Parity Group ID

Displays the parity group ID.

RAID Level

Displays the RAID level. If an LDEV is an external volume, a hyphen (-) is displayed.

Drive Type/RPM

Displays the data drive type and RPM. When the volume is the external volume, Drive Type displays External Storage.

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.

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, the item is displayed as enabled or disabled. If the LDEV is not an external volume, a hyphen (-) is displayed.

Encryption

Displays the information about parity group encryption.

  • Enable: Encryption setting of a parity group in which the LDEV is placed is enabled. Or the pool-VOL which is 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 pool-VOL which is enabled 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): External volume.

This item is not displayed when using Virtual Storage Platform G200.

Accelerated Compression

Displays information about the accelerated compression of the parity group comprised of LDEVs.

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

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

- (hyphen): The parity group with accelerated compression is not supported.

Resource Group Name (ID)

Displays the resource group names and IDs of the LDEV. The ID is provided in parentheses.

External LDEV Tier Rank

Specify the tier rank of the external volume. If there is no external volume in the Available Pool Volumes table or Selected Pool Volumes table, you cannot select this option.

Add

When you select a row in the Available Pool Volumes table and click Add, the selected pool-VOL is added to the Selected Pool Volumes table.

NoteUp to 1,024 volumes can be added including the volumes already in the pool.

When adding a volume to the pool for which Multi-Tier Pool is enabled, note the following:

For a pool, you can add volumes whose Drive Type/RPM settings are the same and whose RAID Levels are different. For example, you can add the following volumes to the same pool:

  • Volume whose Drive Type/RPM is SAS/15K and whose RAID Level is 5 (3D+1P)
  • Volume whose Drive Type/RPM is SAS/15K and whose RAID Level is 5 (7D+1P)
Note

For details about adding LDEVs carved from the accelerated compression-enabled parity groups, Guidelines for pools when accelerated compression is enabled.

Remove

When you select a row in Selected Pool Volumes table and click Remove, the selected pool-VOL is removed from the Selected Pool Volumes table.
