How to Delete a Data Replication Device Group From an SRDF Protection Group

Language:

Note - You can also accomplish this procedure by using the Oracle Solaris Cluster Manager browser interface. Click Partnerships, click the partnership name, then click the protection group name. In the Data Replication Components section, highlight the data replication device group name and click Remove. For more information about Oracle Solaris Cluster Manager, see Chapter 13, Using the Oracle Solaris Cluster GUI, in Oracle Solaris Cluster System Administration Guide .

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.

Log in to a cluster node.
You must be assigned the Geo Management rights profile to complete this procedure. For more information, see Securing Geographic Edition Software in Oracle Solaris Cluster Geographic Edition Installation and Configuration Guide .
Remove the device group.
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
```
device-group

Specifies the name of the data replication device group

protection-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.
