Use the steps in this task to create and configure a Hitachi TrueCopy protection group. If you want to use Oracle Real Application Clusters, see How to Create a Protection Group for Oracle Real Application Clusters.
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 Hitachi TrueCopy Protection Group Configuration to a Secondary Cluster.
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.
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 partnershipname -o localrole -d truecopy [-p property [-p…]] \ protectiongroupname
Specifies the name of the partnership.
Specifies the role of this protection group on the local cluster as either primary or secondary.
Specifies that the protection group data is replicated by the Hitachi TrueCopy software.
Specifies the properties of the protection group.
You can specify the following properties:
Description – Describes the protection group.
Timeout – Specifies the timeout 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.
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.
This example creates a Hitachi TrueCopy protection group on cluster-paris, which is set as the primary cluster.
# geopg create -s paris-newyork-ps -o primary -d truecopy \ -p Nodelist=phys-paris-1,phys-paris-2 tcpg
This example creates a Hitachi TrueCopy protection group, tcpg, for an application resource group, resourcegroup1, that is currently online on cluster-newyork.
Create the protection group without the application resource group.
# geopg create -s paris-newyork-ps -o primary -d truecopy \ -p nodelist=phys-paris-1,phys-paris-2 tcpg
Activate the protection group.
# geopg start -e local tcpg
Add the application resource group.
# geopg add-resource-group resourcegroup1 tcpg
