If a data table without fallback (or from a specific-AMP archive) is restored while one or more AMPs that must also be restored are offline, restore the data table to each of the offline AMPs as soon as the AMPs come back online.
The exclusive utility lock is automatically placed on the data table for the all-AMPs restore and on each offline processor when the AMPs return to an online status. The lock allows Teradata Archive/Recovery Utility to finish the restoring process before the table can be accessed.
