Re-Import Delivery Units that failed during SAP HANA Upgrade

Here are two possibilities exist.

You can re-import the failed delivery units via Modeler perspective [Modeler Perspective-->Quick View --> Import -->SAP HANA Content --> Delivery Unit --> Select System for re-import --> Select "Server" --> Select "Delivery Unit" --> Select Actions "Overwrite inactive objects" and "Activate Objects"]

Alternatively if many delivery units failed during upgrade you could just update the repository using the utility "hdbupdrep", you can find the utility on the OS under the path

/usr/sap/<SID>/SYS/global/hdb/install/bin>

Once the repository is updated log will be written under /var/tmp directory and will have the following naming convention.

/var/tmp/hdb_<SID>_UpdateRepository_<timestamp>/hdbupdrep.log
