Adding Data Replication Device Groups to an SRDF Protection Group

Language:

This section provides procedures for adding an SRDF data replication device group. For details about configuring an SRDF data replication protection group, see How to Create and Configure an SRDF Protection Group.

How to Add a Data Replication Device Group to an SRDF Protection Group

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, click Add. For more information about Oracle Solaris Cluster Manager, see Chapter 13, Using the Oracle Solaris Cluster Manager Browser Interface in Oracle Solaris Cluster 4.3 System Administration Guide.

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 4.3 Geographic Edition Installation and Configuration Guide.
Geographic Edition supports runnging SRDF in zone clusters by using Solutions Enabler client/server mode. If the protection group is in a zone cluster run the following steps:
1. On all nodes of the zone cluster create file /var/cluster/geo/srdf/srdfpgname_config.
2. Set the environment variables SYMCLI_CONNECT and SYMCLI_CONNECT_TYPE in the config file.
```
# mkdir /var/cluster/geo/srdf
# echo "SYMCLI_CONNECT_TYPE=REMOTE" >>  /var/cluster/geo/srdf/srdfpg_config
# echo "SYMCLI_CONNECT=SYMAPI_SERVER2" >>  /var/cluster/geo/srdf/srdfpg_config
```
  For an example illustrating a Solutions Enabler client/server configuration, see Solutions Enabler Client/Server Configuration Example .
Create a data replication device group in the protection group.
This command adds a device group to a protection group on the local cluster and propagates the new configuration to the partner cluster if the partner cluster contains a protection group of the same name.
```
# geopg add-device-group -p property [-p…] device-group protection-group
```
–p property
Specifies the properties of the data replication device group.

You can specify the following SRDF properties:
- DG_or_CG – Specifies that the device group is an SRDF device group.
  
  You must set this property to DG.
- R1SID – Specifies the primary (RDF1) EMC Symmetrix ID of the EMC Symmetrix devices.
  
  The data replication layer automatically sets the value of this property. You should specify the primary (RDF1) EMC Symmetrix ID of the EMC Symmetrix devices if you change the settings of the EMC Symmetrix host.
- R2SID – Specifies the secondary (RDF2) EMC Symmetrix ID of the EMC Symmetrix devices.
  
  The data replication layer automatically sets the value of this property. You should specify the secondary (RDF2) EMC Symmetrix ID of the EMC Symmetrix devices if you change the settings of the EMC Symmetrix host.
device-group

Specifies the name of the new data replication device group.

protection-group

Specifies the name of the protection group that will contain the new data replication device group.
For information about the names and values that are supported by Geographic Edition software, see Appendix B, Legal Names and Values of Geographic Edition Entities, in Oracle Solaris Cluster 4.3 Geographic Edition System Administration Guide.

For more information about the geopg command, refer to the geopg(1M) man page.

Example 6 Adding a Data Replication Device Group to an SRDF Protection Group

This example adds the SRDF data replication device group to the srdfpg protection group.

# geopg add-device-group devgroup1 srdfpg
