We were restoring DB2v8 running SAP at our DR site with 3590 tapes . The restore ran until it got to the next tape then blow with an SQL2025N 40 error .. Stating could not access "TSM" media ..Clean drives and reran the restore .Failed again "code 14" .....I struck it up as a bad tape ...Is a SQL2025N error result of a bad tape or is it something else ....And were can I find on the net DB2 erros and messages ...
