A. Geographic Edition Properties for Hitachi TrueCopy and Universal Replicator
You can obtain an overall view of the status of replication, as well as a more detailed runtime status of the Hitachi TrueCopy or Universal Replicator replication resource groups. The following sections describe the procedures for checking each status.
Displaying a Hitachi TrueCopy or Universal Replicator Runtime Status Overview
Displaying a Detailed Hitachi TrueCopy or Universal Replicator Runtime Status
The status of each Hitachi TrueCopy or Universal Replicator data replication resource indicates the status of replication on a particular device group. The status of all the resources under a protection group are aggregated in the replication status. This replication status is the second component of the protection group state. For more information about the states of protection groups, refer to Monitoring the Runtime Status of the Geographic Edition Software in Oracle Solaris Cluster Geographic Edition System Administration Guide.
To view the overall status of replication, look at the protection group state as described in the following procedure.
You must be assigned the Basic Solaris User RBAC rights profile to complete this procedure. For more information about RBAC, see Geographic Edition Software and RBAC in Oracle Solaris Cluster Geographic Edition System Administration Guide.
# geoadm status
Refer to the Protection Group section of the output for replication information. The information that is displayed by this command includes the following:
Whether the local cluster is enabled for partnership participation
Whether the local cluster is involved in a partnership
Status of the heartbeat configuration
Status of the defined protection groups
Status of current transactions
# clresource status
Refer to the Status and Status Message fields for the data replication device group you want to check.
See Also
For more information about these fields, see Table 2-6.
The Geographic Edition software internally creates and maintains one replication resource group for each protection group. The name of the replication resource group has the following format:
rg-tc_truecopyprotectiongroupname
If you add a Hitachi TrueCopy or Universal Replicator device group to a protection group, Geographic Edition software creates a resource for each device group. This resource monitors the status of replication for its device group. The name of each resource has the following format:
r-tc-truecopyprotectiongroupname-truecopydevicegroupname
You can monitor the status of replication of this device group by checking the Status and Status Message of this resource. Use the clresource status command to display the resource status and the status message.
The following table describes the Status and Status Message values that are returned by the clresource status command when the State of the Hitachi TrueCopy or Universal Replicator replication resource group is Online.

For more information about the clresource status command, see the clresource(1CL) man page.
