Primary Volume

The P-VOL information.

Values:

• LDEV ID: The P-VOL's LDEV identifier.
• LDEV Name: The P-VOL's LDEV name.
• Port ID: Port name of the P-VOL LDEV's LUN path.

• LUN ID: The LUN identifier of the P-VOL LDEV's LUN path.
• Attribute: The P-VOL's attribute.
• Capacity: The P-VOL's volume capacity.
• CLPR: The P-VOL's CLPR ID.
• Encryption: The P-VOL's encryption information.
  • Enabled: Encryption is enabled for the parity group to which the 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 the 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.

  A hyphen (-) is displayed if the P-VOL is an external volume or migration volume. When the P-VOL is a DP-VOL, the pool to which a P-VOL's LDEV belongs in 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.
• T10 PI: The P-VOL's T10 PI attribute information.
  • Enabled: The P-VOL's T10 PI attribute is enabled.
  • Disabled: The P-VOL's T10 PI attribute is disabled.

Copy Type

The types of pairs.

Values:

• SI-L1: SI L1
• SI-L2: SI L2

Secondary Volume

The S-VOL information.

Values:

• LDEV ID: The S-VOL's LDEV identifier.
• LDEV Name: The S-VOL's LDEV name.
• 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 identifier of the S-VOL LDEV's LUN path.
• Attribute: The S-VOL's attribute.
• Capacity: The S-VOL's volume capacity.
• CLPR: The S-VOL's CLPR ID.
• Encryption: The S-VOL's encryption information.
  • Enabled: Encryption is enabled for the parity group to which the S-VOL's LDEV belongs, or the S-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 the S-VOL's LDEV belongs, or the S-VOL is a V-VOL associated with a pool in which a pool volume has encryption disabled.
  • Mixed: The pool to which the 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.

  A hyphen (-) is displayed if the S-VOL is an external volume or migration volume. When the S-VOL is a DP-VOL, the pool to which S-VOL's 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.
• T10 PI: The S-VOL's T10 PI attribute information.
  • Enabled: The S-VOL's T10 PI attribute is enabled.
  • Disabled: The S-VOL's T10 PI attribute is disabled.

Split Type

The split type.

Values:

• Non Split: The pair is not split.
• Quick Split: The pair is split, and then the data is copied so that the S-VOL is immediately available for read and write I/O. Any remaining differential data is copied to the S-VOL in the background.
• Steady Split: Differential data is copied, and then the pair is split.

Copy Pace

The system option that determines the rate at which you want the storage system to copy data.

Values:

• Slower: Improved host server I/O performance but slower processing speed.
• Medium: Average processing speed and host server I/O performance.
• Faster: Faster processing speed but slower host server I/O performance.

Mirror Unit

The mirror unit number.
