2.16 Remote Copy Targets

Figure 2-8. Target Definitions (Single Pair, Bidirectional)
In the previous figure,
■ the Remote Copy target system is InServ2 for the Volume Group X on InServ1.
■ the Remote Copy target system is InServ1 for the replicated volume group Volume Group
X.r on InServ2.
■ the Remote Copy target system is InServ1 for the Volume Group Y on InServ2.
■ the Remote Copy target system is InServ2 for the replicated volume group Volume Group
Y.r on InServ1.
■ the target definitions are simply the names of the storage servers (InServ1 and InServ2) in
relation to each other.
The relationship between target definitions and the server pairs described previously holds
true for all valid Remote Copy configurations (bidirectional, unidirectional, N-to-1, 1-to-N, and
synchronous long distance). The server on which the volume groups originate (the primary
server), defines the target as its backup server.
