The following table describes the items in this table.

olh-note.gif The Selected Pairs table appears on the Confirm window and the Split Pairs window of the Split Pairs wizard. The table for the items on the Confirm window is displayed with that window.

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.

  • (VSP G1000, G1500, and VSP F1500) Emulation Type: The P-VOL's emulation type.

  • (VSP Gx00 models and VSP Fx00 models) Attribute: The P-VOL's attribute.

  • Capacity: The P-VOL's volume capacity

  • CLPR: The P-VOL's CLPR ID.

Copy Type

The types of pairs.

Values:

  • SI-L1: SI L1

  • SI-L2: SI L2

  • (VSP G1000, G1500, and VSP F1500) SIMF: SIz

  • TI: HTI

Snapshot Group

HTI only.

The snapshot group name.

If the pair is not a Thin Image pair, a hyphen appears.

If the pair is a Thin Image pair and the snapshot group is not set, a blank appears.

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.

Secondary Volume

The S-VOL information.

Values:

  • LDEV ID: The S-VOL's LDEV identifier

  • LDEV Name: The S-VOL's LDEV name

  • (VSP G1000, G1500, and VSP F1500) Emulation Type: The S-VOL's emulation type.

  • (VSP Gx00 models and VSP Fx00 models) Attribute: The S-VOL's attribute.

  • Capacity: The S-VOL's volume capacity

  • CLPR: The S-VOL's CLPR ID

Pool Name (ID)

HTI only.

The pool name and identifier.

For pairs that are not Thin Image, a hyphen appears.

Mirror Unit

The mirror unit number.

Cascade

(VSP G1000, G1500, and VSP F1500)

Indicates whether cascade pairs can be created.

Enabled: Cascade pairs can be created.

Disabled: Cascade pairs cannot be created.

A hyphen appears for pairs that are not HTI.

Type

(VSP G1000, G1500, and VSP F1500)

The pair type.

Snapshot: The pair has the snapshot attribute.

Clone: The pair has the clone attribute

A hyphen appears for pairs that are not HTI.

Topology ID

(VSP G1000, G1500, and VSP F1500)

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.

Split Type list

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.

For HTI, this value is not shown.

  • Steady Split: Splits the pair after all of the differential data is copied.

For HTI, only Steady Split: can be selected.

Copy Pace list

SI and SIz only.

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.

For HTI pairs with the snapshot attribute, you cannot select the copy pace and a hyphen appears.
