Viewing local replication summary information

You can view summary local replication information, such as the number of pairs for each software application you are using, in the summary section of the Local Replication window.

Procedure

  1. Navigate to the Local Replication window.

In Command Suite:

  1. On the Resources tab, click Storage Systems, and then expand the storage system tree.

  1. Right-click the target storage system, and then select Local Replication.

In Device Manager - Storage Navigator:

  1. In the Explorer pane, click Storage Systems, expand the storage system tree, expand Replication, and then click Local Replication.

  1. In the summary section of the Local Replication window, view the following information:

Number of Pairs

The number of pairs for each local replication software application type. The total number of pairs is shown on the Total line.

Default: ShadowImage, ShadowImage for Mainframe, and Thin Image

Number of Consistency Groups

The number of consistency groups that are in use and the consistency groups limit in the storage system.

Snapshot Estimated Manageable Capacity

The Thin Image pair’s estimated manageable capacity, which is the estimated pair capacity that you can create using the remaining shared (or control) memory capacity. This value varies depending on the number of Thin Image P-VOLs you add or delete and the number of Thin Image pairs you create.

If the value is less than 128.00 TB, the icon is shown.

Number of Pair Tables

The number of pair tables. This number varies depending on the combination of software applications you are using.

Values:

- SI/SIMF/Volume Migration: The number of SI, SIz, and Volume Migration pair tables in use, and the SI, SIz, and Volume Migration pair table limit in the storage system.

- HTI: The number of HTI pair tables in use and the HTI pair table limit in the storage system.

Number of Differential Tables

The number of differential tables that are in use and the differential table limit in the storage system. This number does not include the number of differential tables that FCv2/FCSE Relationships use.
