Figure 2-14 Management of Pair configuration by Mirror Descriptors
Correspondence of configuration file and mirror descriptors
The group name and MU# that are noted in the HORCM_DEV section of the
configuration definition file are assigned to the corresponding mirror
descriptors. This outline is described in the following table. "Omission of
MU#" is handled as MU#0, and the specified group is registered to MU#0 on
ShadowImage/Copy-on-Write Snapshot and TrueCopy/Universal Replicator/
global-active device. Also, when you note the MU# in HORCM_DEV, the
sequence of the MU# can be random (for example, 2, 1, 0).
