How to Modify a Hitachi TrueCopy Data Replication Device Group

Steps

1. Log in to one of the cluster nodes.

   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.

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-settings [-p...] \ TC-device-group-name protection-group-name

   -p property-settings

   Sets 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.

   TC-device-group-name

   Specifies the name of the new data replication device group

   protection-group-name

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