LUN ID

Identifier of the selected logical unit.

LDEV ID

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

LDEV Name

Name of the LDEV.

Host Group Name / iSCSI Target Alias

Name of the host group or iSCSI target.

iSCSI Target Name

Name of the iSCSI target.

Host Mode

The host mode of the host group.

The number of host mode options that are enabled.

Port ID

Identifier of the port on this volume.

Type

Type of the port.

Fibre: Fibre channel port.

iSCSI: iSCSI port.

Emulation Type

Emulation types for the logical volume (or logical device).

Capacity

Size of the logical volume.

Provisioning Type

Provisioning type assigned to this logical volume.

Basic: Internal volume.

External: External volume.

DP: DP-VOL

Snapshot: Thin Image volume.

LDEV Attribute

Displays the attribute of the LDEV.

Command Device: Command device.

Remote Command Device: Remote command device.

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

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

Command Device Attributes

If the logical volume is used as a command device, indicates the status of the attributes on this LDEV.

• Security: Indicates the status of command device security is (enable or disable).

• User Authentication: Indicates the status of user authentication (enable or disable).

• Device Group Definition: Indicates the status of device group definition (enable or disable).

Access Attribute

Access attribute assigned to this LDEV.

Read/Write: Both read and write operations are permitted on the logical volume.

Read-only: Read operations are permitted on the logical volume.

Protect: Neither read nor write operations are permitted.

Number of Paths

Number of paths set for the LDEV.

UUID

User-definable LUN identifier. This field is blank if the UUID is not set.

CLPR

Cache logical partition numbers.

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

Encryption

Displays the encryption information about the pool.

• Enable: Encryption setting of a parity group or virtual volume associated with pool-VOLs containing LDEV is enabled.

• Disable: Encryption setting of a parity group or virtual volume associated with pool-VOLs containing LDEV is disabled.

• Mixed: In the pool, 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. 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.

ALUA Mode

Asymmetric Access States

Asymmetric access states of the port. When using iSCSI, a hyphen (-) is displayed.

Active/Optimized: Access from the host is preferentially performed on this port.

Active/Non-Optimized: When the Active/Optimized port is disabled, access from the host is performed on this port.

T10 PI

T10 PI attribute setting (Enabled or Disabled) on LDEV.

Data Direct Mapped LDEV

Displays LDEV ID of pool-VOL in the pool of the data direct mapping attribute. A hyphen (-) appears if the data direct mapping attribute is disabled.

Virtual Storage Machine

Information about the virtual storage machine.

• Model / Serial Number: Model name and serial number of the virtual storage machine that has LDEV.

• LDEV ID: Virtual LDEV ID. If a Virtual LDEV ID is not assigned to LDEV, this column is blank.

• Device Name: Virtual device name, which is a combination of the virtual emulation type, virtual LUSE volume number, and the virtual CVS attribute.
