Failed to execute SQL scripts for Database

Upgrade from Veeam Backup & Replication 7 to 8 may fail with "Failed to execute SQL scripts for Database <Databasename>"

 

The issue is caused by mediapools which are not linked to any library but still contain tape media entries. This may happen when the library or standalone drive was exchanged, and the tape mediapools and media were migrated manually into the new library / standalone drive without cleaning up old entries accordingly.

The logs show issues such as follows:
***Veeam*** SRV: [timestamp]:<00000001> [VEEAM|ERROR] ExecuteNonQuery failed for Database 'VeeamBackup'. (Microsoft.SqlServer.Management.Smo.FailedOperationException)
...
***Veeam*** SRV: [timestamp]:<00000001> [VEEAM|ERROR] Cannot insert the value NULL into column 'media_pool_id', table 'VeeamBackup.dbo.Tape.tape_mediums'; column does not allow nulls. UPDATE fails.

Execute the following SQL Script to finish the cleanup, after which you can proceed with the upgrade as usual.

USE VeeamBackup

DECLARE @id uniqueidentifier

DECLARE c CURSOR FOR
    SELECT
        t.id
    FROM
        [Tape.tape_mediums] t
        INNER JOIN [Tape.media_pools] m ON t.media_pool_id = m.id
    WHERE
        NOT EXISTS(SELECT * FROM [Tape.libraries] l WHERE l.id = m.library_id)

OPEN c
    
WHILE 1 = 1
BEGIN
    FETCH NEXT FROM c INTO @id
    if (@@FETCH_STATUS <> 0)
        BREAK

    EXEC [Tape.delete_tape_medium_from_catalogue] @tape_medium_id = @id
    DELETE FROM [Tape.tape_mediums] WHERE id = @id
END

CLOSE c
DEALLOCATE c

BEGIN
    DELETE FROM [dbo].[Tape.media_pools]
    WHERE
    NOT EXISTS(SELECT 1 FROM [dbo].[Tape.libraries] l where l.id = library_id)
END
