How to Replicate the Hitachi TrueCopy Protection Group Configuration to a Partner Cluster

Before You Begin

Before you replicate the configuration of a Hitachi TrueCopy protection group to a partner cluster, ensure that the following conditions are met:

• The protection group is defined on the remote cluster, not on the local cluster.

• The device groups in the protection group on the remote cluster exist on the local cluster.

• The application resource groups in the protection group on the remote cluster exist on the local cluster.

• The Auto_start_on_new_cluster property of the resource group is set to False. You can view this property by using the scrgadm command.

  # scrgadm -pvv -g apprg1 | grep Auto_start_on_new_cluster

  Set the Auto_start_on_new_cluster property to False as follows:

  scrgadm -c -g apprg1 -y Auto_start_on_new_cluster=False

Steps

1. Log in to phys-newyork-1.

   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.

   phys-newyork-1 is the only node on the secondary cluster. For a reminder of which node is phys-newyork-1 , see Figure 2–1.

2. Replicate the protection group configuration to the partner cluster by using the geopg get command.

   This command retrieves the configuration information of the protection group from the remote cluster and creates the protection group on the local cluster.

   phys-newyork-1# geopg get -s partnership-name [protection-group]

   -s partnership-name

   Specifies the name of the partnership from which the protection group configuration information should be retrieved and the name of the partnership where the protection will be created locally.

   protection-group

   Specifies the name of the protection group

   If no protection group is specified, then all protection groups that exist in the specified partnership on the remote partner are created on the local cluster.

   Note –

   The geopg get command replicates Sun Cluster Geographic Edition related entities. For information about how to replicate Sun Cluster entities, see Replicating and Upgrading Configuration Data for Resource Groups, Resource Types, and Resources in Sun Cluster Data Services Planning and Administration Guide for Solaris OS.

The following example illustrates how to replicate the configuration of tcpg from cluster-paris to cluster-newyork:

# rlogin phys-newyork-1 -l root
phys-newyork-1# geopg get -s paris-newyork-ps tcpg
