When you change the SLP config, you create a new version.
So, if there is a problem with version x (same source and target STU) and you change this config to new STU, you create version x+1.
The job that ran against version x will keep on trying to use the incorrect STU as per version x config.
If you are happy that the new config is correct, you need to list version numbers, then modify the SLP version with incorrect STU to change to correct STU.
Start by listing all versions for this SLP:
nbstl Weekly_Oracle_TapeBackup -L -all_versions
