Hi,

I am not sure if this is a udev or distribution issue.
In openSUSE 11.0 with kernel 2.6.25 and udevd version 120 I have following symlinks in /dev/tape/by-id:
lrwxrwxrwx 1 root root 10 Apr 21 15:06 scsi--nst -> ../../nst4
lrwxrwxrwx 1 root root 9 Apr 21 15:06 scsi-35123456000002710 -> ../../sg2

further in openSUSE 11.1 in the /etc/udev/rules.d directory there are no rules for the tapes, but the /dev entries for st*, nst* and sg* are created.

The problem I have, NetBackup will not recognize the tapes in 11.1, it complains about the Device File and the device path, but it works perfect in 11.0. Are there any considerable changes in configuration files between these two versions of udev for the tapes?

Thanks and Regards,
Horst Simon
