Configuration definition for cascading volume pairs
The RAID Manager software (HORCM) is capable of keeping track of up to seven pair associations
per LDEV (one for Continuous Access Synchronous/Continuous Access Journal, two for Continuous
Access Journal, three for Business Copy/Snapshot/Snapshot, one for Snapshot). By this
management, RAID Manager can be assigned to seven groups per LU that describes seven mirror
descriptors for a configuration definition file.
Figure 25 Mirror Descriptors and Group Assignment
Correspondence of the configuration file and mirror descriptors
The group name and MU# which are described in HORCM_DEV of a configuration definition file
are assigned the corresponding mirror descriptors, as outlined in
Table 18 (page 89) . "Omission
of MU#" is handled as MU#0, and the specified group is registered to MU#0 on Business Copy
and Continuous Access Synchronous. Also, the MU# that is noted for HORCM_DEV in
Table 18 (page 89) reflects a random numbering sequence (for example, 2, 1, 0).
