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.

1. Navigate to the Local Replication window.

In Hitachi Command Suite:

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

2. 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.

2. 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 and Thin Image

• Number of Consistency Groups

The number of consistency groups that are in use and the consistency groups limit in a VSP G200, G400, G600 storage system.

• Snapshot Estimated Manageable Capacity

The HTI pair’s estimated manageable capacity, which is the estimated HTI pair capacity that you can create using the remaining SM capacity. This value varies depending on the amount of HTI P-VOLs you add or delete and the number or HTI pairs you create.

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

 This value is a rough estimation and changes as you add and delete HTI pool-VOLs or HTI pairs. This value does not guarantee that the HTI pairs of the indicated capacity have been successfully created.

• Number of Pair Tables

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

Values:

- SI/Volume Migration: The number of SI and Volume Migration pair tables in use and the SI and Volume Migration pair table limit in a VSP G200, G400, G600 storage system.

- HTI: The number of HTI pair tables in use and the HTI pair table limit in a VSP G200, G400, G600 storage system.

• Number of Differential Tables

The number of differential tables that are in use and the differential table limit in a VSP G200, G400, G600 storage system.

 Differential tables are not used in HTI.
