Using snapclones to cascade data replication across three sites
NOTE:
An HP Business Copy EVA license is requir ed for the following procedur e.
This procedure allows you to move copies of your data to a second remote location using HP Command
View EVA and snapclones. The remote location can be an array without a replicating relationship to the
array where the data was created. Exact co pies of the virtual disks containing the data are created by
using snapclones, and these are placed into a DR group for movement to the remote system.
For example, in Figure 14 a production environment contains a DR g roup that replicates between arrays
at Site 1 and Site 2. The DR group contains two virtual disks (05–06vdisk1 and 05–06vdisk2) that are to
be archived on another array (Site 3). A snapclone of each virtual disk is created on the Site 2 array.
