If data in a standard device used for the service is damaged while it is in sync with a BCV, data in the BCV is also damaged. In this case data can be restored from tape back to the standard device.
Data can be restored while the services are stopped and the application volume is not in use.
In this configuration, access cannot be gained from backup server Node3 to disk emcpower2. Therefore, after data held in emcpower1 is restored from tape while emcpower2 is detached temporarily, synchronization copying from emcpower1 to emcpower2 must be performed by reattaching emcpower2. When access can be gained from Node3 to both emcpower1 and emcpower2, it is not required that emcpower2 be detached temporarily since data can be restored from tape back to both emcpower1 and emcpower2.
