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.
Groups are created using the swsrpsetvol command.
Information for created groups can be displayed using the swsrpvolinfo command.
Example
Two groups (called GRP1) consisting of a source volume and a replica volume are created.
# /opt/FJSVswsrp/bin/swsrpsetvol -Xgroup GRP1 /dev/hdisk10@SRC /dev/hdisk20@TARG-1 swsrpsetvol completed # /opt/FJSVswsrp/bin/swsrpsetvol -Xgroup GRP1 /dev/hdisk11@SRC /dev/hdisk21@TARG-1 swsrpsetvol completed # /opt/FJSVswsrp/bin/swsrpvolinfo -L Server Original-Volume Size Replica-Volume Size Copy Op-Server Group SRC /dev/hdisk10@SRC 4.0 Gbyte /dev/hdisk20@TARG-1 4.0 Gbyte bi-direction both GRP1 SRC /dev/hdisk11@SRC 4.0 Gbyte /dev/hdisk21@TARG-1 4.0 Gbyte bi-direction both GRP1 #
