LDEV ID

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

LDEV Name

LDEV name, including the combination of prefix characters and the initial number.

Data Direct Mapping

Information about the data direct mapping.

• LDEV ID: LDEV ID of the pool-VOL in the pool of the data direct mapping attribute, or LDEV ID of the DP-VOL of the data direct mapping attribute. If the data direct mapping attribute is disabled, a hyphen (-) is displayed.

• Parity Group ID: Parity Group ID of the pool-VOL in the pool of the data direct mapping attribute. If the data direct mapping attribute is disabled, a hyphen (-) is displayed.

Parity Group ID

Parity group identifier.

Drive Type/RPM

Drive type and RPM in use on this LDEV.

Pool Name (ID)

Pool name (pool identifier).

RAID Level

RAID level. An asterisk "*" indicates that the parity group from which the LDEV is carved is interleaved (concatenated).

Capacity

LDEV capacity.

Provisioning Type

Type of LDEV.

Basic: Internal volume.

DP: DP-VOL.

External: External volume.

Snapshot: Thin Image volume.

ALU: LDEV of the ALU attribution.

Format Type

Format type.

CLPR

Cache logical partition number, in ID:CLPR format.

For detailed information about CLPRs, see the Performance Guide for Virtual Storage Platform Gx00 and Fx00 Models.

MP Unit ID

MP unit identifier. If Auto is selected, the identifier is automatically assigned.

Multi-Tier Pool

Displays whether Dynamic Tiering is enabled or disabled.

Enable: The LDEV for Dynamic Tiering is displayed.

Disable: The LDEV for Dynamic Provisioning is displayed.

Active Flash

Indicates whether active flash is enabled or disabled.

Enabled: The LDEV is for active flash.

Disable: The LDEV is for Dynamic Tiering.

Hyphen (-): The LDEV is for Dynamic Provisioning.

Full Allocation

Displays the status of the setting for the full allocation in a pool associated with the V-VOL.

• Enable: Full allocation of all DP-VOL pages is performed.

• Disable: Full allocation of all DP-VOL pages is not performed.

Tiering Policy

Displaying the tiering policy name and identifier for the LDEV.

New Page Assignment Tier

Displays the new page assignment tier for the LDEV.

Relocation Priority

Relocation priority assigned to the LDEV.

Attribute

Displays the attribute of the LDEV.

ALU: LDEV of the ALU attribution.

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

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

Encryption

Displays information about the 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: Pool-VOLs whose encryption settings are enabled and pool-VOLs whose encryption settings are 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. For DP-VOL of Dynamic Provisioning, either the pool-VOL in the pool that owns DP-VOL is an external volume or that pool is being blocked

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.

T10 PI

Displays the T10 PI attribute information (Enabled or Disabled) on LDEV.

Resource Group Name (ID)

Resource group name and identifier of which this LDEV is a member.

Virtual Storage Machine

Displays the information about the virtual storage machine.

• Model / Serial Number: The model name and serial number of the virtual storage machine having the LDEV.

• Attribute: Virtual LDEV attribute. If the attribute is not set for LDEV, this column is blank.
