Split Pairs window

Primary Volume

P-VOL information for the pairs you have selected to split.

Values:

• LDEV ID The P-VOL's LDEV identification number.
• LDEV Name The P-VOL's LDEV name.
• Emulation Type(VSP 5000 series) The P-VOL's emulation type.
• Attribute The P-VOL's attribute.
• Capacity The P-VOL's capacity.
• CLPR The P-VOL's CLPR ID.

Copy Type

The volume’s copy type.

Values:

• TI HTI pair

Snapshot Group

The snapshot group name.

Information is displayed for this item only if you have configured a snapshot group for the HTI pair.

Status

The pair status.

For more information, see Thin Image Advanced pair status definitions.

Secondary Volume

The S-VOL information for the pairs you have selected to split.

Values:

• LDEV ID The S-VOL's LDEV identification number.
• LDEV Name The S-VOL's LDEV name.
• Emulation Type(VSP 5000 series) The S-VOL's emulation type.
• Attribute The S-VOL's attribute.
• Capacity The S-VOL's capacity.
• CLPR The S-VOL's CLPR ID.

Pool Name (ID)

The pool name and identification number.

Mirror Unit

The mirror unit number.

Cascade

Indicates whether a cascaded pair can be created.

• Enabled Cascaded pairs can be created.
• Disabled Cascaded pairs cannot be created.

A hyphen (-) displays for non-HTI pairs.

Type

The pair type.

• Snapshot A pair with the snapshot attribute.
• Clone A pair with the clone attribute or diff clone attribute. Thin Image Advanced does not support cloning.

  In the TI Pairs window, if Diff Compare Volume displays the LDEV ID, the diff clone attribute is set for the pair. If Diff Compare Volume displays a hyphen (-), the clone attribute is set for the pair.

A hyphen (-) displays for non-HTI pairs.

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 root volume and the mirror unit number.

Split Type

The mode in which you want to split the selected pairs.

Values:

• Quick Split The pair is split and then remaining differential data is copied to the S-VOL in the background. Specify this value when you want to write to or read from the S-VOL immediately after splitting a pair.
• Steady Split The differential data is copied to the S-VOL and then the pair is split.

  Note: This value is only available if you specify the copy type as TI.

Default: Steady Split

Copy Pace

The speed at which the S-VOL is copied.

For Thin Image pairs with the snapshot attribute, this item cannot be selected. A hyphen (-) is displayed.
