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 information about how different Resource status values map to actual replication pair states, see Table 10–6.
You can check the status of the replication resources by using the scstat -g command as follows:
phys-paris-1# scstat -g |
Running the scstat -g command might return the following:
... --Resources -- Resource Name Node Name State Status Message ------------- --------- ----- -------------- Resource: r-tc-tcpg1-devgroup1 phys-paris-2 Offline Offline Resource: r-tc-tcpg1-devgroup1 phys-paris-1 Online Faulted - P-VOL:PSUE Resource: hasp4nfs phys-paris-1 Offline Offline Resource: hasp4nfs phys-paris-2 Offline Offline ... |
The aggregate resource status for all device groups in the protection group is given by using the geoadm status command. For example, the output of the scstat -g command in the preceding example, indicates that the Hitachi TrueCopy device group, devgroup1, is in the PSUE state on cluster-paris. Table 10–6 indicates that the PSUE state corresponds to a resource status of FAULTED. So, the data replication state of the protection group is also FAULTED. This state is reflected in the output of the geoadm status command, which display the state of the protection group as Error.
