Using the Volume Snapshot Feature
104 VERITAS Volume Manager User’s Guide - VEA
To reattach a snapshot mirror to the original volume, do the following:
1. Right-click the volume whose snapshot you want to reattach.
A context menu is displayed.
2. Select Snap > Snap Back.
3. Specify whether the snapshot volume is resynchronized with the original volume, or
the original volume is synchronized to the snapshot volume and click OK.
Note One situation where you might want to resynchronize to the snapshot volume
rather than the original volume is the case where something has happened to the
original volume so that its data integrity is no longer sound.
The snapshot mirror is reattached to the original volume and the snapshot volume is
deleted if it is the last plex of the volume. (If the snapshot volume has other mirrors
associated with it, it is not deleted.)
Dissociating a Snapshot Volume (Volume Snap Clear)
The volume Snap Clear procedure permanently breaks the association between a
snapshot and its original volume. The snapshot volume becomes an independent volume.
Snap Clear permanently removes a snapshot mirror from a volume. Snap Clear can be
specified only after the snapshot command has been issued.
To permanently remove a snapshot mirror from a volume, do the following:
1. Right-click on the volume, whose snapshot mirror you are removing.
A context mirror is displayed.
2. Select Snap>Snap Clear.
A message box is displayed asking you to confirm the snap clear operation for the
specified volume.
3. Click Yes.
The snapshot mirror is permanently disconnected from the original volume and is no
longer displayed on the Volume Manager console.
