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

Status

The pair status.

A hyphen (-) is displayed 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 volume (root volume for Thin Image pairs) and the mirror unit number.
