ARC1231 Specific AMP RESTORE/COPY not allowed when re-hashing data
When re-hashing data rows during a RESTORE/COPY operation, all data must be loaded before the re-hashing/re-distribution/disk-sort operation can take place. Also, only all-AMP restores to the target machine are allowed. Therefore, there is no need to perform a specific-AMP restore in this scenario. The utility terminates in error if the user attemptssuch an operation as a reminder of this fact.
This is a FATAL error.
