From an application perspective, what should be done prior to performing an SRDF Failback operation?
Before performing an SRDF Failback operation, it is crucial to stop accessing the R2 devices to ensure data consistency and avoid potential conflicts during the failback process. Once access to the R2 devices has been halted, the failback command can be executed. After the command has successfully run, access to the R1 devices can be resumed. This ensures a smooth transition and data integrity. Therefore, the most appropriate action is to stop accessing the R2 devices, run the command, and then start accessing the R1 devices.
stop r2, run command, start r1
Resumes operation back on the primary host accessing the source devices—R1s. All changes that are made to the R2s when failed over are transferred back to the source devices
