Selected Pairs table

Item

Description

Local Storage System

Information about volumes in the accessed system.

  • LDEV ID: LDEV identifier.

  • LDEV Name: LDEV name.

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

  • (VSP Gx00 models and VSP Fx00 models) Attribute: LDEV attribute.

  • Capacity: Capacity of the volume.

  • CLPR: CLPR ID of the volume.

Copy Type

Type of pair:

  • TC: TrueCopy

  • (VSP G1000, G1500, and VSP F1500) TCMF: TrueCopy for Mainframe

Status

Pair status.

Copy Priority

Order that pairs are resynchronized.

Remote Storage System

Information about the remote system.

  • Model / Serial Number: Model and serial number.

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

  • LDEV ID: LDEV identifier.

Path Group ID

TC only.

Path group identifier.

CTG ID

Pair's consistency group identifier.

CTG Utilization

Whether the consistency group is shared by multiple storage systems.

  • Single: The consistency group consists of a single pair of primary and secondary storage systems.

  • Multi: The consistency group consists of multiple storage systems.

Preserve Mirror Status (VSP G1000, G1500, and VSP F1500)

  • Blank: Indicates that it is a Preserve Mirror status without any problem or it is not a Preserve Mirror pair.

  • Withdrawn: Indicates that pair volume data does not match due to suspending copy of Compatible FlashCopy® V2.

Copy Priority

Order that pairs are resynchronized.

Setting Fields

Item

Description

Primary Volume Fence Level

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

  • Data: The P-VOL cannot be written to.

  • Status: The P-VOL can be written to only if the primary system can change the S-VOL status to PSUE (TC) or Suspend (TCz). If the primary system cannot change the S-VOL status, the P-VOL cannot be written to.

  • Never: The P-VOL can be written to.

Copy Pace

Number of tracks to be copied per remote I/O during the operation. The default is 15. The range is different depending on the volume emulation type.

  • OPEN-V (TC): The range is 1 to 4.

- 1 is slow. This setting limits the impact on host I/O to maintain storage system performance.

- 2 and 3 is medium.

- 4 is fast. This setting increases the impact on host I/O and might result in decreased storage system performance.

If you enter a number from 5 to 15, the speed of 4 (fast copy pace) is used.

  • (VSP G1000, G1500, and VSP F1500) Other than OPEN-V (TCz): You can specify 3 or 15 from the list.

- 3 is slow. This setting limits the impact on host I/O to maintain storage system performance.

- 15 is fast. This setting increases the impact on host I/O and might result in decreased storage system performance.

  • For TC, the range is 1-15.

  • (VSP G1000, G1500, and VSP F1500) TCz options are 3 and 15.

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

TCz only.

  • Enable: The host I/O time stamp is transferred from P-VOL to S-VOL.

  • Disable: The host I/O time stamp is transferred from P-VOL to S-VOL.

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