Hitachi VSP G400 User Guide

1. Create cascaded pairs and distribute data in the P-VOL. Assign the clone
attribute to the volume to be a new distributor (S-VOL 3 in the figure).
2. Clone pairs.
By cloning pairs, S-VOL 3 and S-VOL 1 become unpaired volumes (DP-VOLs)
in the same status, and S-VOL 3 can be a new distributor. As a result, the
overhead of the Thin Image pairs can be reduced.
Workflow for creating groups and storing snapshot data using CCI
You can use CCI raidcom commands to create a consistency or snapshot
group and to split pairs to store the snapshot data for the group.
With Thin Image, ShadowImage, and ShadowImage for Mainframe, you can
create up to 2,048 consistency groups in a VSP family storage system.
The following figure illustrates how snapshot data is stored for a consistency
or snapshot group using CCI raidcom commands.
