Breaking a mirror takes away a redundant mirror (or plex) of a volume and assigns it another drive letter. The data on the new volume is a snapshot of the original volume at the time of breaking. Breaking off a plex of the mirrored volume does not delete the information, but it does mean that the plex that is broken off no longer mirrors information from the other plex or plexes in the mirrored volume.

For further details on mirror break off, refer to the Storage Foundation Administrator's Guide.

Note:

To create the mirror break-off, the volumes must have been created with mirrored plexes.

To create mirror break-offs

Right-click on the volume from which you want to break a mirror. Click Mirror from the menu that comes up, and then select Break from the submenu. The Break Mirror dialog box appears.
Select the mirror you want to break off from the Break Mirror dialog box. Choose whether or not to assign a drive letter to the broken-off volume. You can assign a specific letter by selecting from the list or you can accept the default.
Click OK to break-off the mirror.

This mirror break-off volume gives you the data on the Secondary data volume up to the point before the mirror break-off operation was performed.
