Validating a Hitachi TrueCopy or Universal Replicator Protection Group

During protection group validation, the Hitachi TrueCopy or Universal Replicator data replication subsystem validates the following:

• The horcmd daemon is running on at least one node that is specified in the Nodelist property of the protection group. The data replication layer also confirms that a path to a Hitachi TrueCopy or Universal Replicator storage device exists from the node on which the horcmd daemon is running.

• The device group specified is a valid Sun Cluster device group or a CVM device group if the Cluster_dgs property is specified. The data replication layer also verifies that the device group is of a valid type.

• The properties are validated for each Hitachi TrueCopy or Universal Replicator device group that has been added to the protection group.

When the geoadm status output displays that the Configuration status of a protection group is Error, you can validate the configuration by using the geopg validate command. This command checks the current state of the protection group and its entities.

If the protection group and its entities are valid, then the Configuration status of the protection groups is set to OK. If the geopg validate command finds an error in the configuration files, then the command displays a message about the error and the configuration remains in the error state. In such a case, you can fix the error in the configuration, and run the geopg validate command again.

How to Validate a Hitachi TrueCopy or Universal Replicator Protection Group

Before You Begin

Ensure that the protection group you want to validate exists locally and that the Common Agent Container is online on all nodes of both clusters in the partnership.

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. Validate the configuration of the protection group.

   This command validates the configuration of the protection group on the local cluster only. To validate the protection group configuration on the partner cluster, run the command again on the partner cluster.

   # geopg validate protectiongroupname

   protectiongroupname

   Specifies a unique name that identifies a single protection group
