ECC Group

Number of parity group where the LDEV belongs.

Output example: X-Y (decimals)

• If the number starts with "E" (for example, E1-1), the parity group contains external volumes.
• If "LDEV Type" is Dynamic Provisioning or Thin Image, a hyphen is output.

ORACLE CHECK SUM

Information about whether this LDEV is an Oracle check sum target.

• On
• Off

Current MPU

Number of the MP unit currently controlling the LDEV.

(MPU-10, MPU-11, MPU-20, MPU-21)

Setting MPU

Number of the MP unit configured to control LDEV.

(MPU-10, MPU-11, MPU-20, MPU-21)

Allocated

Information about whether this LDEV is allocated to a host.

• "Y" is output for volumes accessible to the host.

Pool Name

The pool's name¹

• If the provisioning type is Dynamic Provisioning, the name of the pool related to the logical volume is displayed.
• If the attribute is Pool, the name of the pool where the logical volume belongs is displayed.
• When neither of the above are displayed, the pool name is blank.

CmdDevSecurity

Indicates whether Security is specified as the attribute for the command device.

• Enabled: Command device security setting is set.
• Disabled: Command device security setting is not set.
• Blank: "LDEV Attribute" is not CMDDEV.

CmdDevUserAuth

Indicates whether User Authentication is specified as the attribute for the command device.

• Enabled: User authentication setting is set.
• Disabled: User authentication setting is not set.
• Blank: "LDEV Attribute" is not CMDDEV.

CmdDevDevGrpDef

Indicates whether Device Group Definition is specified as the attribute for the command device.

• Enabled: Device group definition setting is set.
• Disabled: Device group definition setting is not set.
• Blank: "LDEV Attribute" is not CMDDEV.

Resource Group ID (LDEV)

LDEV resource group ID (number in the decimal format)

Resource Group Name (LDEV)

LDEV resource group name (0 to 1,023, decimal)

Encryption

Indicates whether the parity group identified by ECC Group is encrypted.

• For internal volumes: Enabled (encrypted) or Disabled (not encrypted)
• For external volumes: blank

T10 PI

Indicates the T10 PI attribute set for the LDEV.

• Enabled
• Disabled
• Blank if "LDEV Emulation" is not OPEN-V.

ALUA Mode

Indicates whether the ALUA mode is enabled.

• Enabled: ALUA mode is enabled.
• Disabled: ALUA mode is disabled.

Accelerated Compression

Indicates whether accelerated compression is enabled.

For internal volumes:

• Enabled: accelerated compression is enabled.
• Disabled: accelerated compression is disabled.

If the parity group with LDEV does not support accelerated compression, a blank space is displayed. Also, for external volumes, a blank is displayed.

Notes:

1. If the character string contains a comma, the comma is converted to a tab.
