Unplanned switch operations

In Cascaded/SRDF, if the workload site fails, an unplanned switch operation is required to move the production workload to one of the target sites.

  • To switch production to the synchronous target site, convert the configuration to Concurrent SRDF/Star.

    Only local data can be kept because the local data is ahead of the data at the asynchronous target site.

  • When switching production to the asynchronous target site, the local data or the data at the synchronous target site can be kept.

The following image shows unplanned switch operations that are available from each state.

NOTE:

The rounded rectangles that represent the target sites after a switch are not color coded because the definition of the workload site and the target sites can change after the switch.
