Checking the Runtime Status of EMC Symmetrix Remote Data Facility Data Replication

You can obtain an overall view of the status of replication as well as a more detailed runtime status of the EMC Symmetrix Remote Data Facility replication resource groups. The following sections describe the procedures for checking each status:

Displaying an EMC Symmetrix Remote Data Facility Runtime Status Overview

The status of each EMC Symmetrix Remote Data Facility 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 Sun Cluster Geographic Edition Software in Sun 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.

How to Check the Overall Runtime Status of Replication

1. Access a node of the cluster where the protection group has been defined.

   You must be assigned the Basic Solaris User 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. Check the runtime status of replication.

   # 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

3. Check the runtime status of data replication for each EMC Symmetrix Remote Data Facility device group.

   # clresourcegroup status sc_geo_dr-SRDF-protectiongroupname # clresource status sc_geo_dr-SRDF-protectiongroupname-srdf dgname

   Refer to the Status and Status Message fields for the data replication device group you want to check.

Displaying a Detailed EMC Symmetrix Remote Data Facility Runtime Status

The Sun Cluster 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:

# sc_geo_dr-SRDF-protectiongroupname

If you add an EMC Symmetrix Remote Data Facility device group to a protection group, Sun Cluster 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:

# sc_geo_dr-SRDFprotectiongroupname-srdfdevicegroupname

You can monitor the status of replication of this device group by checking the Status and Status Message of this resource. Use the clresourcegroup status command to display 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 EMC Symmetrix Remote Data Facility replication resource group is Online.

For more information about these values, refer to the EMC Symmetrix Remote Data Facility documentation.

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