Difference in device files between 11.0 and 11.1

Hi,

I used Veritas NetBackup on openSUSE 11.0 64-bit without problems, but on openSUSE 11.1 64-bit it can not create the tape device. The installation is on the same hardware only different boot partition. When I create the tape drive in the application it fails with Invalid path and the detailed description shows No configuration device file exist. It uses the /dev/nst0 path which exist and in /proc/scsi all the files exist too.

Anyone know if there are any differences in creation of the device files between these two versions?

Thanks and Regards,
Horst
