This relationship between target definitions and remote-copy system pairs is true for all valid
remote-copy configurations:
•
unidirectional
•
bidirectional
•
M-to-N
•
SLD
For the system that contains the primary volume groups (the primary system), the target system is
the same as the backup system. For the system that contains the secondary volume groups (the
backup system), the target system is the same as the primary system.
Figure 31 (page 100) illustrates target definitions in a bidirectional remote-copy pair.
Figure 31 Target Definitions for a Bidirectional Remote-Copy Pair
In Figure 31 (page 100) , the target definitions for each volume group on each system are shown
in Table 5 (page 100) :
Table 5 Volume Group Target Definitions (One Bidirectional Remote-Copy Pair)
Target Definition/Target System Volume Group and Location
System2 For volume group groupX on System1
System1 For secondary volume group groupX.r11 on System2
System1 For volume group groupY on System2
System2 For secondary volume group groupY.r96 on System1

Remote-Copy Target System
Because the primary and backup roles can change, HP 3PAR Remote Copy uses the term
remote-copy target system to refer to the other storage system in a remote-copy pair.
For example, in a remote-copy pair composed of System1 and System2, the target system for
System1 is System2, and the target system for System2 is System1.
