How to Configure Trust Between Two Clusters

Before You Begin

Ensure that the following conditions are met:

• The cluster on which you want to create the partnership is running.

• The geoadm start command must have already been run on this cluster and the partner cluster. For more information about using the geoadm start command, see Enabling the Sun Cluster Geographic Edition Software.

• The cluster name of the partner cluster is known.

• The host information of the partner cluster must defined in the local host file. The local cluster needs to know how to reach the partner cluster by name.

  If the clusters are in different domains, include the domain name in the entry, as logicalhostname.domainname. However, the cluster name itself must not include the domain.

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.

2. Import the public keys from the remote cluster to the local cluster.

   Running this command on one node of the local cluster imports the keys from the remote cluster to one node of the cluster.

   # geops add-trust -c remotepartnerclustername

   -c remotepartnerclustername[.domainname]

   Specifies the logical hostname of the cluster with which to form a partnership. The logical hostname is used by the Sun Cluster Geographic Edition software and maps to the name of the remote partner cluster. For example, a remote partner cluster name might resemble the following:

   cluster-paris

   If the clusters are on different domains, also specify the fully qualified domain name. For example, two clusters in a partnership that have different domains might resemble the following:

   cluster-paris.france cluster-newyork.usa

   When you use this option with the add-trust or remote-trust subcommand, the option specifies the alias where the public keys on the remote cluster are stored. An alias for certificates on the remote cluster has the following pattern:

   remotepartnercluster.certificate[0-9]*

   Keys and only keys that belong to the remote cluster should have their alias match this pattern.

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

3. Repeat the preceding steps on a node of the remote partner cluster.

   If you choose to use the Sun Cluster Manager, skip this step. The Sun Cluster Manager handles all nodes in a single operation.

4. Verify trust from one node of each cluster.

   # geops verify-trust -c remotepartnerclustername[.domainname]

   This command verifies the trust from the node on which you run the command to all nodes of the partner cluster. If you choose to use the Sun Cluster Manager, it verifies the trust from all nodes of the local cluster to all nodes of the partner cluster
