How to Create and Configure a Sun StorEdge Availability Suite 3.2.1 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 Sun StorEdge Availability Suite 3.2.1 Protection Group Configuration to a Partner Cluster

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. Create a new protection group by using the geopg create command.

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

   # geopg create -s partnership-name -d avs \ -o local-role [-p property-settings [-p...]] \ protection-group-name

   -s partnership-name

   Specifies the name of the partnership

   -d avs

   Specifies that the protection group data is replicated by Sun StorEdge Availability Suite 3.2.1

   -o local-role

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

   -p property-setting

   Sets the properties of the protection group

   The properties you can set are the following:

   • Description – describes the protection group

   • Timeout – specifies the timeout period for the protection group in seconds

   • Enable_volume_set – when set to true, specifies that the volume set will be automatically enabled at protection group creation time

     For more information about automatically enabling a volume set, see Enabling a Sun StorEdge Availability Suite 3.2.1 Volume Set.

   • Nodelist – Lists the host names of the machines that can be primary for the device group in the protection group.

   For more information about the properties you can set, see Appendix A, Standard Sun Cluster Geographic Edition Properties.

   protection-group-name

   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.

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

   Before creating the protection group, the data replication layer validates that the configuration is correct.

   If the validation is successful, the local Configuration status is set to OK and the Synchronization status is set to Error.

   If the validation is unsuccessful, the protection group is not created.

Example 7–2 Creating and Configuring a Protection Group

The following example illustrates how to create a Sun StorEdge Availability Suite 3.2.1 protection group on cluster-paris, which is set as the primary cluster:

phys-paris-1# geopg create -s paris-newyork-ps -d avs -o primary \
-p Nodelist=phys-paris-1,phys-paris-2 avspg
