Figure 2-15 ShadowImage cascade connection and configuration file

ShadowImage

Since ShadowImage is a mirrored configuration within one storage system, it
can be described as a volume of the cascading connection according to two
configuration definition files. For a ShadowImage-only cascading connection,
the specified group is assigned to the mirror descriptor (MU#) of
ShadowImage, specifically defining "0" as the MU# for ShadowImage. Figure
2-16 Pairdisplay on HORCMINST0 on page 2-32 - Figure 2-18 Pairdisplay on
HORCMINST0 on page 2-32 show ShadowImage cascading configurations
and the pairdisplay information for each configuration.
