    That's because you don't need to backup /dev files. They are recreated when you install the OS anyway so there is no point backing them up and they are character special files (not text or binary)

    set-up a /usr/openv/netbackup/exclude_list and add /dev to it - this will then skip trying to back them up.

    Also add /proc to your exclude_list too.

     

    Here is a useful Technote:

    Excluding files from backup. Addendum to VERITAS NetBackup System Administrator's Guide for UNIX and Linux, Volume 1

    http://www.symantec.com/docs/TECH73478

    /dev/ is not mentioned here, but exclude it in your exclude_list file and re-run the backup

Probably bpbkar and not bpbkar32, right?

bpbkar is on Unix/Linux client. 
bpbkar32 on Windows.

I am sure you know by now what my next question is going to be... 
WHY NBU 6.5 on the client? 

Try to add 
IGNORE_XATTR = YES
to bp.conf on the client.

And please exclude /dev from filesystem backups - there is no point in backing it up.
Device files are automatically created during OS install and system reboot.

Please also verify that OS patches are up to date on the client.
We have seen that similar issues were fixed on HP-UX clients when OS patches were updated.
 

 

*** EDIT *** 
OOPS! ignore my IGNORE_XATTR... already set!

PLEASE upgrade NBU on this client, check that OS patches are up to date, and exclude /dev...
