Item

Description

Primary Volume

The P-VOL information.

Values:

  • LDEV ID The P-VOL's LDEV identification number.
  • LDEV Name The P-VOL's LDEV name. If you have not allocated an LDEV to the S-VOL, a hyphen (-) is displayed.
  • Port ID The port name of the P-VOL LDEV's LUN path.
  • Host Group Name / iSCSI Target Alias The host group name and ID or iSCSI target alias and ID of the P-VOL LDEV's LUN path.
  • iSCSI Target Name The P-VOL's iSCSI target name.
  • LUN ID The LUN identification number of the P-VOL LDEV's LUN path.
  • Attribute The P-VOL's attribute.
  • Capacity The P-VOL's capacity.
  • CLPR The P-VOL's CLPR ID.
  • (VSP 5000 series) Encryption P-VOL's encryption information.
    • Enabled Encryption is enabled for the parity group to which P-VOL's LDEV belongs, or a V-VOL is associated with a pool in which a pool volume has encryption enabled.
    • Disabled Encryption is disabled for the parity group to which P-VOL's LDEV belongs, or a V-VOL is associated with a pool in which a pool volume has encryption disabled.
    • Mixed The pool to which the P-VOL's LDEV belongs contains both pool volumes for which encryption is enabled and ones for which encryption is disabled..

      Note: Data encryption is not ensured in an LDEV with Mixed encryption status. If you want to manage data encryption, use LDEVs with the Enabled or Disabled status.

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

      For DP-VOLs, the pool to which an LDEV belongs is an external volume or blocked.

  • Capacity Saving Information about the P-VOL's capacity saving function.
    • Compression The compression function is used.
    • Deduplication and Compression The deduplication function and the compression function are used.
    • Disabled The capacity saving function is not used.
  • Compression AccelerationCompression accelerator settings.
    • Enabled: The compression accelerator setting is enabled.
    • Disabled: The compression accelerator setting is disabled.
    • - (hyphen): The compression accelerator setting is not available for an LDEV. Alternatively, the compression accelerator setting is available for an LDEV whose capacity saving setting is Disabled and whose capacity saving status is Disabled.
  • T10 PIThe P-VOL's T10 PI attribute information.
    • EnabledThe P-VOL's T10 PI attribute is enabled.
    • DisabledThe P-VOL's T10 PI attribute is disabled.

Snapshot Group

The snapshot group name.

Information is displayed for this item only if you have configured a snapshot group for the HTI pair.

Status

The pair status.

For more information about pair status, see Thin Image pair status definitions.

Secondary Volume

The S-VOL information.

Values:

  • LDEV IDThe S-VOL's LDEV identification number. If you have not allocated an LDEV to the S-VOL, this item is blank.
  • LDEV NameThe S-VOL's LDEV name. If you have not allocated an LDEV to the S-VOL, a hyphen (-) is displayed.
  • Port ID Port name of the S-VOL LDEV's LUN path.
  • Host Group Name / iSCSI Target Alias The host group name and ID or iSCSI target alias and ID of the S-VOL LDEV's LUN path.
  • iSCSI Target Name The S-VOL's iSCSI target name.
  • LUN ID The LUN identification number of the S-VOL LDEV's LUN path.
  • Attribute The S-VOL's attribute.
  • Capacity The S-VOL's capacity.
  • CLPR The S-VOL's CLPR ID.
  • (VSP 5000 series) Encryption S-VOL's encryption information.
    • Enabled Encryption is enabled for the parity group to which S-VOL's LDEV belongs, or a V-VOL is associated with a pool in which a pool volume has encryption enabled.
    • Disabled Encryption is disabled for the parity group to which S-VOL's LDEV belongs, or a V-VOL is associated with a pool in which a pool volume has encryption disabled.
    • Mixed The pool to which S-VOL's LDEV belongs contains both pool volumes for which encryption is enabled and ones for which encryption is disabled..

      Note: Data encryption is not ensured in an LDEV with Mixed encryption status. If you want to manage data encryption, use LDEVs with the Enabled or Disabled status.

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

      For DP-VOLs, the pool to which an LDEV belongs is an external volume or blocked.

  • Capacity Saving Information about the S-VOL's capacity saving function.
    • Compression The compression function is used.
    • Deduplication and Compression The deduplication function and the compression function are used.
    • Disabled The capacity saving function is not used.
  • Compression AccelerationCompression accelerator settings.
    • Enabled: The compression accelerator setting is enabled.
    • Disabled: The compression accelerator setting is disabled.
    • - (hyphen): The compression accelerator setting is not available for an LDEV. Alternatively, the compression accelerator setting is available for an LDEV whose capacity saving setting is Disabled and whose capacity saving status is Disabled.
  • T10 PIThe S-VOL's T10 PI attribute information.

Pool Name (ID)

The pool name and identification number.

Mirror Unit

Cascade

Indicates whether a cascaded pair can be created.

  • Enabled Cascaded pairs can be created.
