When errors occur, the NEC Storage ReplicationControl SQL Option outputs the details of the standard
output, the standard error output, the event log and the operation trace.
The messages described in “NEC Storage Manager Message Handbook” are output to the standard
output, to the standard error output and to the event log. Take appropriate corrective actions in
accordance with the explanation in the messages.
In the operation trace, the messages output to the standard output, to the standard error output and to the
event log are recorded together with detailed internal information.
Operation trace is output to the same file as that of NEC Storage ReplicationControl. The data is
output to iSMrpl.log file in etc\trace folder, within installation folder of NEC Storage
ReplicationControl. Check the contents by using the text editor, etc.
When errors occur, Microsoft SQL Server 2000 outputs the contents of errors to the error log. For
details, refer to Microsoft SQL Server 2000 Books Online.

With the NEC Storage ReplicationControl SQL Option’s error output, if “iSM13689: Failed to snapshot
execution.” and “iSM13690: Failed to sql command execution.” are output without outputting other
error messages immediately before, a certain form of error has occurred at the Microsoft SQL Server
2000.
Take appropriate measures while referring to the error log of Microsoft SQL Server 2000.
In the event that the I/O is high for the disk, the snapshot backup may fail. In this case, if the error log
of Microsoft SQL Server 2000 is referred to, error code 844 or 845 is output.
The snapshot backup must be executed when the operations load is lowered. It is necessary to review
the operation if this error occurs.
