A little history, we used to have an automated script that refreshed QA database from production using rman duplicate. They (UNIX guys) moved the TSM server and modified the configuration files on production to make the backups go to the new server. Nobody modified the settings or setup new settings on the new server for the QA machine to be able to read backups done by prod. Now when I updated my dsm.sys file to point to the new server, I get the following while running an rman duplicate. RMAN-03002: failure of Duplicate Db command at 08/17/2010 14:26:06 RMAN-03015: error occurred in stored script Memory Script ORA-19501: read error on file "oqllff55_1_1", blockno 1 (blocksize=512) ORA-27190: skgfrd: sbtread2 returned error ORA-19511: Error received from media manager layer, error text: ANS1314E (RC14) File data currently unavailable on server Am I missing something at the TSM server layer, like permissions, creation of new nodes etc? Any help would be much appreciated. Thanks. -Amit.
