Hi,

I am not sure if this is a udev or distribution issue. It works in
openSUSE 11.0 and before, but no more in openSUSE 11.1. I am too have seen
this problem with other distributions

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

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.

In openSUSE 11.0 with kernel 2.6.25 and udevd version 120 I have
following symlinks in /dev/tape/by-id:

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.

I don't know about any major changes, there was only  simple bug-fix:
  http://git.kernel.org/?p=linux/hotplug/udev.git;a=commitdiff;h‹739d

All rules which are not supposed to edited by users, are in
/lib/udev/rules.d/ now.

Hi Kay,

The NetBackup device configuration wizard gives the error "No configuration 
device file found". I think it has to do with the new symlinks in /sys/class 
scsi_tape.

In the working configuration it has no symlinks under the scsi_tape directory, 
the entries are directories for nst* and st*.

In the not working configuration the entries are symlinks and this I think 
confuses NetBackup and cannot find the device configuration files. Is it 
possible to create rules to change it back to directories?

Regards,
Horst
