Introduction

Cross Vraid

Cross Vraid for Snapshot and Snapclone allow customers to change the Vraid type when creating snapshots or snapclones for better disk utilization when making redundant copies of data. Cross Vraid is supported in the following manner:

■Cross Vraid Snapshot (ADD SNAPSHOT) and Snapclones (ADD COPY) within the same disk group.

■Cross Vraid Snapclones (ADD COPY) across disk groups (including standard and FATA disk groups)

The SSSU v3.2 and Command View EVA v3.2 along with VCS v3.020 are required to support Cross Vraid Snaps.

Refer to ADD COPY and ADD SNAPSHOT for more information.
