137 perform a full volume copy operation from the master to the shadow. When the
138 copy completes, the shadow volume data is identical to the master volume data
139 at the moment that it was established. Create an independent shadow if you
140 require two physical copies of the data. An independent shadow volume must be
142 that the master and shadow volumes be the same size for environments where
143 resynchronization from shadow to master is a consideration.

149 Create a dependent shadow when you do not require two physical copies of the
150 data. A dependent shadow volume can be either the same size or smaller than the
151 master volume. A smaller shadow volume is called a \fBCompact Dependent Shadow
157 The following syntax allows you to create an exportable independent shadow

169 An issue arises when using a Compact Dependent Shadow Volume in that its size
172 exceeds the space allocated for the shadow volume, the shadow volume is marked
173 as out of space. It is possible to read from the shadow volume even after it is
175 requested. Once that happens, the read fails and the shadow volume is marked
181 Thus, if the size of the Compact Dependent Shadow Volume is too small, or an

303 \fIbitmap_vol\fR is used for tracking differences between the shadow and master

354 \fIvolume_set\fR is the Point-in-Time Copy shadow set containing the master and
355 shadow volumes. This option provides a fast resynchronization of the shadow
357 segments flagged as different between the master and shadow volumes. It does

384 creating an incremental copy of the shadow. This update copies all 32KB
385 segments flagged as different between the master and shadow volumes. It does
386 not copy all shadow volume data, only changed data. While the data is being
387 copied, the master is dependent upon the shadow volume.
