Hello, I have a 2008 server with sp2 X64. Have installed the backup exec 2010 in trial mode. Tape device is a HP DLT 448 ultrium. I have tried installed different drivers and i have got it to be listed under devices but under media the tape icon has a red mark over it. is there any problem with symantec tape drivers on x64 2008? After Reboot the system drops the tape and then suddenly it can find it again.
Could be driver issues themselves - I had similar issues with out PowrVaulr 114T under Server 2003 x86 R2 using anything newer than the OEM quantum drivers with BE 12.5. You may have luck completely uninstalling the tape drive and reinstalling using older or newer drivers - u might also try calling Symantec to ask of they have recommended drivers for your setup.
