The following table describes the items in this table in the Confirm window of the Split Pairs wizard.

Item

Description

Primary Volume

The P-VOL information.

Values:

  • LDEV ID: The P-VOL's LDEV identifier
  • LDEV Name: The P-VOL's LDEV name
  • Attribute: The P-VOL's attribute.
  • Capacity: The P-VOL's volume capacity
  • CLPR: The P-VOL's CLPR ID

Copy Type

The pair type.

Values:

  • SI-L1: SI L1
  • SI-L2: SI L2
  • TI: HTI

Snapshot Group

HTI pairs only.

The snapshot group name.

If you have not assigned the pair to a snapshot group, a blank is displayed. For non-HTI pairs, a hyphen is displayed.

Status

The status of the pair.

For more information about pair status, select In-System Replication to navigate to the desired software and status information.

Split Type

The split type.

Values:

  • 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. For HTI pairs, a hyphen is displayed.

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.

Secondary Volume

The S-VOL information.

Values:

  • LDEV ID: The S-VOL's LDEV identifier
  • LDEV Name: The S-VOL's LDEV name
  • Attribute: The P-VOL's attribute.
  • Capacity: The S-VOL's volume capacity
  • CLPR: The S-VOL's CLPR ID

Pool Name (ID)

HTI pairs only.

The pool name and ID number.

For non-HTI pairs, a hyphen is displayed.

Mirror Unit

The mirror unit number.

Cascade

Indicates whether cascade pairs can be created.

Snapshot: The pair has the snapshot attribute.

Clone: The pair has the clone attribute

For non-HTI pairs, a hyphen is displayed.

Topology ID The topology ID, which indicates the layer of the pair based on the mirror unit. The topology ID consists of the LDEV ID of the volume (root volume for Thin Image pairs), which is the base of the target pair, and the mirror unit number.
