2840 Data rows discarded due to inconsistent hash codes

Explanation:

During a restore operation, some rows were discarded because of inconsistencies in the row hash codes.

Generated By:

Restore.

For Whom:

End User. Site support representative.

Notes:

Two situations cause this error to occur: 1) During an attempt to restore a row, a row with the same rowid but different data was found on the disk. 2) During a specific-AMP restore, the AMP received a data block containing a row that it does not own, even though reconfiguration has not taken place since the dump. The situation may be caused either by a software bug (the rows were mis-distributed when the dump was taken) or a user error (updating the table before the table was completely restored). In either case, the restore continues unaffected, except that the offending rows are discarded. Associated with this error is a count of the rows discarded.

Remedy:

If the error is caused by an operational error, start the restore process over or accept an incomplete table. If there were no operational errors, contact your Support Representative.
