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 fields displayed by executing swsrpvolinfo (Replication volume information display 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 GDS 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.
Groups are created using swsrpsetvol (Replication volume information setting command).
Information for created groups can be displayed using swsrpvolinfo (Replication volume information display command).
Two groups (called GRP1) consisting of a source volume and a replica volume are created.
