I have a similar problem, I don't even get an error in BE admin console! Jobs just running infinite and tape don't move. Disk based backups have no problem.
Same setup: Windows 2008R2 x64 with (external) LTO-4 tape drive (Dell label, IBM hardware) and Backup Exex 2010 R2.
Have already an open case, but support has currently no clue.
Make sure the SCSI drivers are updated too and make sure the tape drive is not using SCSI id 0 and 1 as they are reserved for the bootable devices and the Library is not connected to a RAID controller . Also disable the removeable storage service .
Thank you for your answer, but no help for me. I had already talked to Dell and Symantec support. Dell even was so cooperative to change the drive with cables!
This is a dedicated "Dell SAS 5/E Adapter Controller" with up-to-date Dell drivers (see link). Because this adapter is not used for booting I do not see the need of changing the ID and I can't see where I could change it. It's probably not important for a SAS device that has a one-to-one connection, too.
Also disable the removeable storage service .
I thought there is no such a service in Windows 2008 any more. What's its exact name?
Any hardware issues are already excluded, except for software like Windows or BE. The drive works fine with Windows 2003 x86 and Linux x64, but not any more with Windows 2008 x64.
I have some interesting log data if someone whant to see them.
That's why I'm curious of any solutions here.
