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 with data direct mapping enabled, or LDEV ID of the DP-VOL data direct mapping enabled. 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 with data direct mapping enabled. 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 to which the LDEV belongs 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.

MP Unit ID

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

Multi-Tier Pool

Displays whether Dynamic Tiering is enabled or disabled.

Enable: The LDEV for Dynamic Tiering .

Disable: The LDEV for Dynamic Provisioning .

Active Flash

Indicates whether active flash is enabled or disabled.

Enabled: The LDEV is for active flash or active flash for mainframe.

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 ID for the LDEV.

New Page Assignment Tier

Displays the new page assignment tier for the LDEV.

Relocation Priority

Relocation priority assigned to the LDEV.

Capacity Saving

Displays the capacity saving setting:

• Compression: The compression function is used.

• Deduplication and Compression: The deduplication and compression functions are used.

• Disabled: The Capacity Saving function is not used.

Attribute

Displays the attribute of the LDEV.

ALU: LDEV of the ALU attribution.

Data Direct Mapping: LDEV with the data direct mapping attribute enabled.

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

Encryption

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 with enabled encryption settings and pool-VOLs with disabled encryption settings 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 or migration volume. As for DP-VOL of Dynamic Provisioning , the pool-VOL in the pool of which DP-VOL belongs is an external volume, or the pool of which DP-VOL belongs is being blocked.

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

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

T10 PI

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

Resource Group Name (ID)

Resource group name and ID 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.
