DSNU1408I csect-name - SOURCE DATA SET dsname DOES NOT MATCH obj-type obj-qual.obj-name DSNUM n
Explanation
The COPYTOCOPY or RECOVER utility issues this message when the DBID or PSID of the source data set does not match the DBID or PSID of the table space or index space for which the copy is made. This error can occur if the data set was reused.
The UNLOAD utility displays this message when no records were UNLOADED from an image copy data set because the OBID for the tables did not match the information in the DBD. This can occur if the tables in the table space were dropped and re-created after taking the image copy.
The COPY utility issues this message when the DBID or PSID of the header page of the target object does not match the information in the DBD. In this case, the source data set dsname will be omitted from the message.
System action
RECOVER attempts to continue processing by falling back to the previous full image copy, if any.
COPYTOCOPY searches for the next available image copy data set with the same START_RBA value as the START_RBA value registered in SYSIBM.SYSCOPY for dsname. If COPYTOCOPY finds a data set, it uses that data set. Otherwise, COPYTOCOPY issues message DSNU1401I.
The UNLOAD utility completes with reason-code four.
If FROMCOPY is specified, processing of this object halts. COPY fails with RC8 and an image copy is not created.
User response
Determine why the data set was reused for the image copy data set that is registered in SYSIBM.SYSCOPY.
If FROMCOPY is specified, correct the COPYTOCOPY utility control statement. Specify a source data set that is an image copy of the table space or index space for which you want additional image copies.
If this message was received for COPY, try to determine how the header page of the object became corrupted, and fix it using the REPAIR utility, if possible. Otherwise, recover the object using a good copy.
If this message was received for UNLOAD, specify a source data set that is an image copy of the table space taken with the current table definitions.
Severity
4 (warning) or 8 (error)
