Torn Smart Copies
ASM/ME Smart Copy operations occur on a per-volume basis, which means that if you create a Smart Copy of a component,
ASM/ME copies the volume on which the component is stored. If different data sets are spanned across a common volume, the
resulting Smart Copy contains partial information for a particular data set. Dell recommends that you place related data sets on
separate volumes to avoid the possibility of creating a torn Smart Copy.
The following figure illustrates a torn Smart Copy configuration.
In the following figure, you can use ASM/ME to copy the data set indicated by Callout 1. This data set consists of data spanning
Volumes A and B. The resulting Smart Copy Set (A2 and B2, with the same data set as Callout 1) contains a full copy of the data
set.
Figure 8. Complete Smart Copy
Consider the configuration shown in the following figure. In this example, two data sets span three volumes. Volume B contains
data from two different data sets (Callouts 1 and 2).
Figure 9. Torn Smart Copy
You can use ASM/ME to copy Component1, indicated by Callout 1. However, ASM/ME performs its Smart Copy operations only
on complete volumes. As a result, ASM/ME must include all the data on Volume B, even though some of it is part of a different
data set (Component2, indicated by Callout 2).
