Dears ,
wish you have a nice day
i have a directory exist on aix client , this directory contain 15 million files
making "ls" command on it not working , because the mechanism of how "ls " work because it is need to buffer output
i use "find . " to display files in it
the backup process on it hanged with status code 13 as it waits long time before it can't find files to backup
at first , i think the problem is from network , so i have to elimante the network by using this command , it also hang
/usr/openv/netbackup/bin/bpbkar -nocont /siebel/siebelfs/att > /dev/null

Try to add touch-file
# touch /usr/openv/netbackup/bpbkar_path_tr
add VERBOSE = 5 into bp.conf
and re-run bpbkar test

As long as the native ls does not work I don't think you can bring Netbackup to work on the full directory.
The options are as I see it:
1) Tune the file cache/OS so that ls works on this directory
2) Split up the backup of this directory, probably only makes sense if it contains sub directories
3) Reduce number of files in this directory, guess it contains some kind of attachments for siebel.
Normally I would suggest accelerator for many files, but as long the OS can't list the files I am not sure that will work.

You can try a raw backup of the file system but since its not able to even do an "ls" this might also not work.

Forget about getting NBU to work if "ls" doesn't work. The location /siebel/siebelfs/att is attachment folder. It looks to me that the sibel admin did not watch this directory and not its to big.
You can't and should not be responsible to fix this, they are doing it wrong. Instead Sibel admin should find a solution.
Some reference about same issue:
