The following steps summarize the process for failing back to the source site. For command examples, see Detailed steps.
- If the source site was not available for a period of time, return the configuration to the source site for composite group HANA_CG:
- Set the SRDF mode to adaptive copy disk to minimize the performance impact of a full restore.
- Restore data from the remote PowerMax to the source site.
- Set data protection to synchronous or asynchronous.
- Re-enable consistency using composite group HANA _CG.
- Swap the personality of the devices to return the configuration to the source site for composite group HANA_CG.
Note: A scheduled failover will have minimal changes between the source and target site.
- Fail over composite group HANA_CG.
- Swap the personality of the composite group HANA_CG.
- Establish the composite group HANA_CG.
- Re-enable consistency using composite group HANA _CG.
