Sun Cluster Geographic Edition Data Replication Guide for Sun StorageTek Availability Suite

Recovering From a Sun StorageTek Availability Suite Data Replication Error

When an error occurs at the data replication level, the error is reflected in the status of the resource in the replication resource group of the relevant device group.

For example, suppose a device group controlled by Sun StorageTek Availability Suite that is called avsdg changes to a Volume failed state, VF. This state is reflected in the following resource status:


Resource Status = "FAULTED"
Resource status message = "FAULTED : Volume failed"

Note –

The Resource State remains Online because the probe is still running correctly.


Because the resource status has changed, the protection group status also changes. In this case, the local Data Replication state, the Protection Group state on the local cluster, and the overall Protection Group state become Error.

To recover from an error state, complete the relevant steps in the following procedure.

ProcedureHow to Recover From a Data Replication Error

  1. Use the procedures in the Sun StorageTek Availability Suite documentation to determine the causes of the FAULTED state. This state is indicated as VF.

  2. Recover from the faulted state by using the Sun StorageTek Availability Suite procedures.

    If the recovery procedures change the state of the device group, this state is automatically detected by the resource and is reported as a new protection group state.

  3. Revalidate the protection group configuration.


    phys-paris-1# geopg validate protectiongroupname 
    
    protectiongroupname

    Specifies the name of the Sun StorageTek Availability Suite protection group

  4. Review the status of the protection group configuration.


    phys-paris-1# geopg list protectiongroupname 
    
    protectiongroupname

    Specifies the name of the Sun StorageTek Availability Suite protection group
