How to Create and Configure an EMC Symmetrix Remote Data Facility Protection Group

Before You Begin

Before you create a protection group, ensure that the following conditions are met:

• The local cluster is a member of a partnership.

• The protection group you are creating does not already exist.

Protection group names are unique in the global Sun Cluster Geographic Edition namespace. You cannot use the same protection group name in two partnerships on the same system.

You can also replicate the existing configuration of a protection group from a remote cluster to the local cluster. For more information, see Replicating the EMC Symmetrix Remote Data Facility Protection Group Configuration to a Partner Cluster.

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. Create a new protection group that uses SRDF replication by using the geopg create command.

   This command creates a protection group on all nodes of the local cluster.

   # geopg create -s partnershipname -o localrole -d srdf [-p property [-p...]] \ protectiongroupname

   -s partnershipname

   Specifies the name of the partnership.

   -o localrole

   Specifies the role of this protection group on the local cluster as either primary or secondary.

   -d srdf

   Specifies that the protection group data is replicated by the EMC Symmetrix Remote Data Facility software.

   -p propertysetting

   Specifies the properties of the protection group.

   You can specify the following properties:

   • Description – Describes the protection group.

   • Timeout – Specifies the time-out period for the protection group in seconds.

   • Nodelist – Lists the host names of the machines that can be primary for the replication subsystem.

   • Cluster_dgs – Lists the device groups where the data is written.

   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.

   protectiongroupname

   Specifies the name of the protection group.

   For information about the names and values that are supported by Sun Cluster Geographic Edition software, see Appendix B, Legal Names and Values of Sun Cluster Geographic Edition Entities, in Sun Cluster Geographic Edition System Administration Guide.

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

Example 2–2 Creating and Configuring an EMC Symmetrix Remote Data Facility Protection Group

This example creates an EMC Symmetrix Remote Data Facility protection group on cluster-paris, which is set as the primary cluster.

# geopg create -s paris-newyork-ps -o primary -d srdf \
-p cluster_dgs=dg1 srdfpg
