6.4.7 Creating groups

6.4.7.1 Conditions for the replication volumes that make up the group

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.

  

6.4.7.2 How to create groups

Groups are created using swsrpsetvol (Replication volume information configuration command).
Information for created groups can be displayed using swsrpvolinfo (Replication volume information display 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
