Checking the Runtime Status of SRDF Data Replication

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

Displaying an SRDF Runtime Status Overview

The status of each SRDF 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.

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 Geographic Edition Software and RBAC in Oracle Solaris 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 SRDF device group.
    # clresourcegroup status sc_geo_dr-SRDF-pgname
    # clresource status sc_geo_dr-SRDF-pgname-dgname

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

For more information about these fields, see Table 2-4.

Displaying a Detailed SRDF Runtime Status

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:

# sc_geo_dr-SRDF-pgname

If you add an SRDF 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, where pgname is the name of the protection group and dgname is the name of the device group:

# sc_geo_dr-SRDF-pgname-dgname

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 SRDF replication resource group is Online.
