Before You Begin
You might delete a data replication device group from a protection group if you added a data replication device group to a protection group. Normally, after an application is configured to write to a set of disks, you would not change the disks.
Deleting a data replication device group does not stop replication or change the replication status of the data replication device group.
For information about deleting protection groups, refer to Deleting Protection Groups and Data Replication Components in Oracle Solaris Cluster Geographic Edition System Administration Guide . For information about deleting application resource groups from a protection group, refer to How to Delete an Application Resource Group From an SRDF Protection Group.
You must be assigned the Geo Management RBAC rights profile to complete this procedure. For more information about RBAC, see Securing Geographic Edition Software in Oracle Solaris Cluster Geographic Edition Installation and Configuration Guide .
This command removes a device group from 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 remove-device-group device-group protection-group
Specifies the name of the data replication device group
Specifies the name of the protection group
When a device group is deleted from an SRDF protection group, the corresponding Oracle Solaris Cluster resource, sc_geo_dr-SRDF-protection-group-device-group, is removed from the replication resource group. As a result, the deleted device group is no longer monitored. The replication resource group is removed when the protection group is deleted.
This example removes an SRDF data replication device group srdfdg from the srdfpg protection group.
# geopg remove-device-group srdfdg srdfpg
