How to Modify a Hitachi TrueCopy or Universal Replicator Data Replication Device Group

1. Log in to a cluster node.

   You must be assigned the Geo Management RBAC rights profile to complete this procedure. For more information about RBAC, see Sun Cluster Geographic Edition Software and RBAC in Sun Cluster Geographic Edition System Administration Guide.

2. Modify the device group.

   This command modifies the properties of a device group in a protection group on the local cluster. Then the command propagates the new configuration to the partner cluster if the partner cluster contains a protection group of the same name.

   # geopg modify-device-group -p property [-p...] TCdevicegroupname protectiongroupname

   -p property

   Specifies the properties of the data replication device group.

   For more information about the properties you can set, see Appendix A, Standard Sun Cluster Geographic Edition Properties, in Sun Cluster Geographic Edition System Administration Guide.

   TCdevicegroupname

   Specifies the name of the new data replication device group.

   protectiongroupname

   Specifies the name of the protection group that will contain the new data replication device group.
