C.2 Bidirectional Synchronous Disaster Recovery Example
The following example contains a disaster recovery cycle for a bidirectional Remote Copy pair
(InServ1/InServ2) with synchronous mode volume groups. The following information
applies to this bidirectional disaster recovery example:
■ The members of the Remote Copy pair are an eight-node cluster called InServ1 and a
four-node cluster called InServ2.
■ Information for InServ1 is as follows:
◆ System ID: 96
◆ Links:
IP address 172.1.1.96
IP address 172.1.2.96
◆ Remote copy nodes: 0 and 1
■ Information for InServ2 is as follows:
◆ System ID: 11
◆ Links:
IP address 172.1.1.11
IP address 172.1.2.11
◆ Remote copy nodes: 0and 1
■ Two virtual volumes on InServ1 called localvv.0 and localvv.1 are the only members of
sync_group_1.
■ Two virtual volumes on InServ2 called remotevv.0 and remotevv.1 are the only
members of sync_group_1.r96, the secondary group that is automatically created at the
same time as sync_group_1.
■ Two virtual volumes on InServ2 called localvv.0 and localvv.1 are the only members of
sync_group_2.
■ Two virtual volumes on InServ1 called remotevv.0 and remotevv.1 are the only
members of sync_group_2.r11, the secondary group that is automatically created at the
same time as sync_group_2.
