Checking the Runtime Status of Sun ZFS Storage Appliance Remote Replication

The Geographic Edition software internally creates and maintains one replication resource group for each protection group. The name of the replication resource group is specified by the user in the configuration as described in How to Create and Configure a Sun ZFS Storage Appliance Protection Group.

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

Overview of Displaying a Sun ZFS Storage Appliance Runtime Status

The status of each Sun ZFS Storage Appliance remote replication resource indicates the status of replication on a particular replication component. 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.

If you add a Sun ZFS Storage Appliance component to a protection group, Geographic Edition software creates a resource for each replication component. This resource monitors the status of replication for its replication component.

You can monitor the status of replication of this replication component by checking the Status and Status Message of this resource. Use the clresourcegroup status command to display resource status and the status message.

How to Check the Runtime Status of Sun ZFS Storage Appliance Replication

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.
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
Check the runtime status of replication for each Sun ZFS Storage Appliance component.
```
# clresourcegroup status zfssa-rep-rg
# clresource status zfssa-rep-rs
```
Refer to the Status and Status Message fields for the replication component you want to check. See Sun ZFS Storage Appliance Replication Resource Group Runtime Status and Status Messages for a list of possible status values and status messages.
List the status of components that are managed by Geographic Edition software.
```
# clresource status -t ORCL.repzfssa
```

Sun ZFS Storage Appliance Replication Resource Group Runtime Status and Status Messages

The following table lists the Status and Status Message values that are returned by the clresource status command when the State of the Sun ZFS Storage Appliance replication resource group is Online.

Table 1-3 Status and Status Messages of an Online Sun ZFS Storage Appliance Replication Resource Group

Status	Status Message
Online	Sending update
Online	Receiving update
Online	Idle
Degraded	The most recent replication update failed because the target system has reached the maximum number of concurrent replication updates.
Degraded	The appliance failed to contact the remote peer. There might be a network connectivity issue or the management software on the target might have failed.
Degraded	A remote procedure call failed on the remote peer. The target system may be running incompatible software.
Faulted	The most recent replication update was cancelled by an administrator.
Faulted	The most recent replication update failed because replication is disabled globally or disabled for this package on the target appliance.
Faulted	The most recent replication update failed because there is insufficient space on this system to create a new project-level snapshot.
Faulted	The most recent replication update failed because the target is running incompatible software.
Faulted	The most recent replication update failed because the target package contains data from a previous replication update that could not be used for an incremental update.
Faulted	The most recent replication update failed because no replication package exists on the target for this replication action.
Faulted	The appliance could not verify the identity of the remote peer.
Unknown	The most recent replication update failed. No additional information is available. Check replication status on the target system. See the replication documentation for more details.
Unknown	Replication is disabled for the project.
Unknown	Continuous mode is set to `false` for the project.
Unknown	Failed to obtain replication key for the project.

For more information about these values, refer to the Sun ZFS Storage Appliance documentation.
