The replication volumes that make up the group (the source volume and the destination volume pairs) must meet the following conditions:
The copy source servers and destination servers must have matching attributes such as size and device configuration.
The operational servers and the copy directions must all match. The values for the operational servers and the copy directions can be checked using the Op-Server and Copy columns displayed by executing the swsrpvolinfo command.
The replication volume information being registered must not be registered in any other group.
Source volumes and destination volumes must not be duplicated within the group.
A replication group cannot have both PRIMECLUSTER GD logical volumes and other types of volumes.
If a Logical Unit (disk) is specified, the information of the replication volume in a partition included in the Logical Unit (disk) must not be registered to another group.
If a Logical Unit (disk) is specified, the information of the replication volume in a partition included in the Logical Unit (disk) must not be registered within the same group.
If the Storage Cluster Continuous Copy function is used, all of the replication volume information in the group must belong to the same TFO group.
Groups are created using the swsrpsetvol command.
Information for created groups can be displayed using the swsrpvolinfo command.
Two groups (called GRP1) consisting of a source volume and a replica volume are created.
