This section provides the following information:
Displaying a Sun StorageTek Availability Suite Runtime Status Overview
Displaying a Detailed Sun StorageTek Availability Suite Runtime Status
You can obtain an overall view of the status of replication, as well as a more detailed runtime status of the Sun StorageTek Availability Suite software from the status of the replication resource groups. The following sections describe the procedures for checking each status.
The status of each Sun StorageTek Availability Suite 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.
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 -v avsdg-rep-rs
Refer to the Status and StatusMessage fields that are presented for the data replication device group you want to check. For more information about these fields, see Table 2-1.
One replication resource group exists for each protection group. The name of the replication resource group has the following format:
avsprotectiongroupname-rep-rg
If you add a Sun StorageTek Availability Suite device group to a protection group, the 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:
avsdevicegroupname-rep-rs
You can monitor the state of the replication resource to give you the overall status of replication. Use the clresource status command as follows to obtain the State and Status Message values for the replication status of the device group:
# clresource status -v avsdg-rep-rs
The State is Online while the resource is online.
The following table describes the Status and Status Message values that are returned by the clresource status command when the State of the Sun StorageTek Availability Suite replication resource group is Online.

For more details about these values, refer to the Sun StorageTek Availability Suite 4.0 Remote Mirror Software Administration and Operations Guide.
For more information about the clresource command, see the clresource(1CL) man page.
