Local Storage System

Information about volumes in the accessed system.

• LDEV ID: LDEV identifier.

• LDEV Name: LDEV name.

• Port ID: Port identifier. TC/UR only.

• Host Group Name/iSCSI Target Alias: Host group name or iSCSI target alias. TC/UR only.

• iSCSI Target Name: iSCSI target name. TC/UR only.

• LUN ID: LUN identifier. TC/UR only.

• Pair Position: UR or URz only. Indicates whether the volume is the P-VOL or S-VOL of the pair.

• (VSP G1000, G1500, and VSP F1500) Emulation Type: Emulation type of the volume.

TCz/TC/URz only.

• Attribute:

• ALU: The volume has the ALU attribute.

• SLU: The volume has the SLU attribute.

• Data Direct Mapping: The volume has the data direct mapping attribute.

If the attribute is not set, a hyphen (-) is displayed. TC and UR only.

• Journal ID: Journal's identifier. UR or URz only.

• Mirror ID: Mirror identifier. UR or URz only.

• Capacity: Capacity of the volume.

• CLPR: CLPR ID of the volume.

• Encryption: Encryption information:

• Enabled: Encryption of the parity group to which the LDEV belongs is enabled, or a V-VOL is associated with a pool in which a pool volume has encryption enabled.

• Disabled: Encryption of the parity group to which the LDEV belongs is disabled, or a V-VOL is associated with a pool in which a pool volume has encryption disabled.

• Mixed: The pool to which the LDEV belongs contains both pool volumes for which encryption is enabled and pool volumes for which encryption is disabled.

Note: Encryption of data is not ensured in an LDEV with the Mixed encryption status. To manage data encryption, use an LDEV in which Encryption is Enabled or Disabled.

For an external volume, a hyphen (-) is displayed.

For V-VOLs of Dynamic Provisioning or Dynamic Provisioning for Mainframe, the pool to which the LDEV belongs is an external volume or blocked.

• Journal Encryption: Journal's encryption status. UR or URz only.

• Enabled: The journal contains encrypted volumes.

• Disabled: The journal contains unencrypted volumes.

• Mixed: The journal contains both encrypted and unencrypted volumes.

Note: Encryption of data is not ensured in an LDEV with the Mixed encryption status. To manage data encryption, use an LDEV in which Encryption is Enabled or Disabled.

A hyphen (-) is displayed if the pool to which the journal volume belongs is an external volume, created by migration, or blocked.

• T10 PI: T10 PI attribute of the volume.

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

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

(VSP G1000, G1500, and VSP F1500) A hyphen (-) is displayed if the emulation type is other than OPEN-V.

Copy Type (VSP G1000, G1500, and VSP F1500)

Type of pair:

• TC: TrueCopy

• UR: Universal Replicator

• TCMF: TrueCopy for Mainframe

• URMF: Universal Replicator for Mainframe

Remote Storage System

Information about volumes in the system connected to the system you accessed.

• Model / Serial Number: Model and serial number.

• Port ID: Port identifier. TC/UR only.

• Host Group ID/iSCSI Target ID: Host group identifier or iSCSI target identifier. TC/UR only.

• LUN ID: LUN identifier. TC/UR only.

• (VSP G1000, G1500, and VSP F1500) SSID: SSID number. TCz only.

• (VSP G1000, G1500, and VSP F1500) LDEV ID: LDEV identifier. TCz/URz only.

• Journal ID: Journal's identifier. UR or URz only.

Path Group ID

Path group identifier. Not shown for TCz.

CTG ID

UR only.

Consistency group identifier.

Fence Level

TC or TCz only

Whether the P-VOL can be written to when the pair is split due to error.

• Data: Cannot be written to.

• Status: Can be written to only if the primary system can change the S-VOL status to PSUE. If the primary system cannot change the S-VOL status, the P-VOL cannot be written to.

• Never: Can be written to.

Initial Copy Type

Pair creation operation type.

Copy Pace

TC or TCz only

Number of tracks to be copied per remote I/O operation.

Initial Copy Priority

Scheduling order for the initial copy operation. The range is 1 to 256, and the default is 32.

CFW Data (VSP G1000, G1500, and VSP F1500)

TCz only.

Whether CFW (DASD fast write) data is copied to the S-VOL.

• Primary Volume Only: Data not copied (default).

• Secondary Volume Copy: Data is copied.

This is displayed only for TCz pairs.

DFW to Secondary Volume (VSP G1000, G1500, and VSP F1500)

TCz only.

Whether the primary system splits the pair when the secondary system cannot copy DFW data to the S-VOL

• Require: Splits the pair.

• Not Require: Does not split.

Host I/O Time Stamp Transfer (VSP G1000, G1500, and VSP F1500)

TCz only.

Whether the host I/O time stamp is transferred from P-VOL to S-VOL.

Error Level

UR or URz only.

Whether to split all pairs in the mirror if a failure occurs during this operation:

• Mirror: Pairs in the mirror are split.

• Volume: Only the failed pair is split.

CFW (VSP G1000, G1500, and VSP F1500)
