LDEV ID

Source volume's LDEV identifier

LDEV Name

Selected LDEV's name. This field is blank if the LDEV name is not set.

Pool Name (ID)

Source volume's pool name and ID number

Pool Capacity

Displays the information of the pool, in which the source volume is installed. If the source volume is not DP-VOL, a hyphen (-) is displayed.

• Total: The total pool capacity.
• Used: The sum of the amount of the pool capacity for allocated pages and the reserved capacity for pages.
• Remaining: The pool free space.

RAID Level

The RAID level of the source volume

Attribute

The attribute of the source volume.

• SLU: The volume has an SLU attribute.
• Data Direct Mapping: The volume of which Data Direct Mapping attribute is enabled.
• NAS Platform (User LU): The volume for storing of the user data for NAS.
• - (hyphen): The volume has no attribute.

Capacity

The source volume's capacity

• Total: The total source volume capacity.
• Mapped: The amount of page capacity of which user data and control information for the source volume are stored. If the source volume is not DP-VOL, a hyphen (-) is displayed.
• Used: The sum of the amount of the allocated page capacity for the source volume and the reserved capacity for pages. If the source volume is not DP-VOL, a hyphen (-) is displayed. If you refer to the used capacity during I/O or copy processing by Volume Migration or the replication program products, for example ShadowImage and Universal Replicator, even if the Full allocation is enabled on the virtual volume, the displayed used capacity may be different from the actual capacity because there is a gap between the times of information gathering about the mapped capacity and the reserved page capacity.

Full Allocation

The information on the status of Full Allocation for the source volume.

• Enabled: The Full Allocation for the source volume is enabled.
• Disabled: The Full Allocation for the source volume is disabled.

If LDEV is an internal volume, an external volume or a migration volume, a hyphen (-) is displayed.

Drive Type/RPM

Displays the data drive type and RPM of the source volume.

CLPR

Indicates the ID number and name of the CLPR corresponding to the source volume's parity group.

Encryption

Information about the encryption set to the source volume:

• Enabled: The encryption for the parity group to which the LDEV as the source volume belongs is enabled. Otherwise, the LDEV is DP-VOL which is allocated to the pool volume of the pool whose encryption is enabled.
• Disabled: The encryption for the parity group to which the LDEV as the source volume belongs is disabled. Otherwise, the LDEV is DP-VOL which is allocated to the pool volume of the pool whose encryption is disabled.
• Mixed: This status appears when two or more of following are specified as pool-VOLs:

  • Volume encryption setting is enabled.

  • Volume encryption setting is disabled.

  • External volume

  Note: When the value is Mixed, the encryption of data is not guaranteed. If you want to manage the encryption of data, use the LDEV of which Encryption is Enabled or Disabled.

• - (hyphen): The LDEV is an external volume or a migration volume.

  For the virtual volume of Dynamic Provisioning, the pool to which the LDEV belongs is an external volume or blocked.

T10 PI

Displays the information about the T10 PI attribute of the volume.

• Enabled: The T10 PI attribute of the volume is enabled.
• Disabled: The T10 PI attribute of the volume is disabled.
