Table 108 Relevant Properties of RemoteStorageSynchronized (continued) Properties Description SyncInterval Specifies that groups that are in asynchronous periodic mode should be periodically synchronized in accordance with the specified value of the replication. 0 means synchronization will not happen unless it is done manually. SyncPolicy Specifies the policy of the Remote Copy volume groups for dealing with I/O failure and error handling of the replication. Valid values are: • no_fail_wrt_on_err - Specifies that if Remote Copy is started for the volume group and a write to the secondary system fails, then the Remote Copy operation is stopped and an I/O error is not returned to the host (default). This allows the application writing the data to continue, but makes the secondary volumes out of date with the primary volumes. • auto_recover - Specifies that if the Remote Copy is stopped as a result of the Remote Copy links going down, the group is restarted automatically after the links come back up. If this policy is enabled for a group while the group is stopped after link failures, it will be only be started when the links come up for the failed target. If the links are already up at the time the policy is set then the group will not be restarted at that time. • no_auto_recover - Specifies that if the Remote Copy is stopped as a result of the Remote Copy links going down, the group must be restarted manually after the links come back up (default). • over_per_alert - If a synchronization of a periodic Remote Copy group takes longer to complete than its synchronization period then an alert will be generated. This is the default behavior. • no_over_per_alert - If a synchronization of a periodic Remote Copy group takes longer to complete than its synchronization period then an alert will not be generated. State Transition During Normal Operation Table below shows the values of CopyState, SyncState and ProgressStatus for various CLI SyncStatus of the volumes under normal environment. "Normal" means that the CLI Target Status field shows "ready".
