Selected Pairs table

The following table lists the items in this table on the Confirm window.

Item

Description

Primary Volume

The P-VOL information.

Values:

  • LDEV IDThe P-VOL's LDEV identification number.
  • LDEV NameThe P-VOL's LDEV name.
  • Port ID The port name of the P-VOL LDEV's LUN path.
  • Host Group Name/iSCSI Target AliasThe host group name of the P-VOL LDEV's LUN path.
  • iSCSI Target NameThe P-VOL's iSCSI target name.
  • LUN IDThe LUN identification number of the P-VOL LDEV's LUN path.
  • Attribute The P-VOL's attribute.
  • CapacityThe P-VOL's capacity.
  • CLPRThe P-VOL's CLPR ID.
  • Encryption P-VOL's encryption information.
    • Enabled Encryption is enabled for the parity group to which P-VOL's LDEV belongs, or the P-VOL is a V-VOL 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 the P-VOL is a V-VOL associated with a pool in which a pool volume has encryption disabled.
    • Mixed The pool to which the P-VOL's LDEV belongs contains two or more of the following:
      • Volume for which encryption is enabled
      • Volume for which encryption is disabled
      • External volume

      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.

Snapshot Data Seq. No.

The sequence number of snapshot data.

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 AliasThe host group name of the S-VOL LDEV's LUN path.
  • iSCSI Target NameThe S-VOL's iSCSI target name.
  • LUN IDThe LUN identification number of the S-VOL LDEV's LUN path.
  • Attribute The S-VOL's attribute.
  • CapacityThe S-VOL's capacity.
  • CLPRThe S-VOL's CLPR ID.
  • Encryption S-VOL's encryption information.
    • Enabled Encryption is enabled for the parity group to which S-VOL's LDEV belongs, or the P-VOL is a V-VOL 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 the P-VOL is a V-VOL associated with a pool in which a pool volume has encryption disabled.
    • MixedThe pool to which S-VOL's LDEV belongs contains two or more of the following:
      • Volume for which encryption is enabled
      • Volume for which encryption is disabled
      • External volume

      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.
    • EnabledThe S-VOL's T10 PI attribute is enabled.
    • DisabledThe S-VOL's T10 PI attribute is disabled.

Pool Name (ID)

The pool name and identification number.

Pool Encryption

The pool's encryption information.

  • EnabledA pool was created by the pool volume for which encryption is enabled.
  • DisabledA pool was created by the pool volume for which encryption is disabled.
  • MixedA pool contains two or more of the following:
    • Volume for which encryption is enabled
    • Volume for which encryption is disabled
    • External volume

Cascade

Indicates whether a cascaded pair can be created.

  • Enabled Cascaded pairs can be created.
