If volume data is damaged, it can be restored from tape.
Data can be restored while service is stopped and the application volume is not in use.
In this configuration access cannot be gained from backup server Node3 to disk c2t1d1. Therefore, after data is restored from tape back to c1t1d1 while c2t1d1 is detached temporarily, resynchronization copying from c1t1d1 to c2t1d1 must be performed by reattaching c2t1d1. When access can be gained from Node3 to both c1t1d1 and c2t1d1, it is not required that c2t1d1 be detached temporarily since data can be restored from tape back to both c1t1d1 and c2t1d1. For details on this restore method, see "Backing Up and Restoring a Logical Volume with No Replication"
