The other shows up as C5173-4000 (incorrectly, as it also has two DLT7000 drives which LTT sees) and refuses firmware upgrade (from 4.04) as HP has only firmware 3.05 as the newest firmware for the -4000.<BR /> <BR /> So either someone flashed an incorrect firmware or someone changed the mainboard of the machine. But how got the 4.x firmware into a machine which only allows 3.x firmware?<BR /> <BR /> Is there any chance to <BR /> 1. tell the machine that it really is a -7000<BR /> 2. force firmware upgrade to 4.06 ?<BR /> <BR /> Any help greatly appreciated<BR /> rgds<BR /> Fussel<BR /> Fri, 08 Apr 2005 01:21:22 GMT https://community.hpe.com/t5/automated-backup/c5173-dlt-library-firmware-problems/m-p/516055#M685 CA1265488 2005-04-08T01:21:22Z https://community.hpe.com/t5/automated-backup/c5173-dlt-library-firmware-problems/m-p/516056#M686 It is possible to force the firmware upgrade using a factory override password for LTT which you can get from the HP call center.
