Expanding a volume that has a snapshot

If you expand a volume that has a snapshot or detached mirror, then you also need to consider increasing the size of the DCO volume that tracks the changes made to the volume. Increasing the size of the DCO volume allows for a more efficient mirror resynchronization process.

Before expanding the volume, you should perform snap back and snap abort operations on the volume. The snap abort operation should be done with the Convert into normal mirror option. This deletes the existing DCO volume and the snap volume becomes the mirror volume with a DCO volume. Right-click the volume and Select remove log to remove the DCO volume. After you expand the volume and prepare the volume for a snapshot with the Select existing mirror for snap option, a new DCO volume is created automatically at the optimal size for the expanded volume.

More information is available about snapshots.
