MSDP 250GB /etc/nbapp-release missing

hello,
 
Here is my netbackup rev details
 
[root]# cat /usr/openv/netbackup/version
HARDWARE LINUX_RH_X86
VERSION NetBackup 9.1.0.1
RELEASEDATE Tue Aug 24 17:26:47 CDT 2021
BUILDNUMBER 0040
 
###
I recently created an MSDP pool as per the tech note:
 
 
 
however ... I forgot step #3 : Create a touch a file /etc/nbapp-release if it doesn’t exist.
 
There is no explanation as to why the above file is required is required.
Everything appears to work fine ... and it is only during my review that I realised my mistake above.
 
However, the MSDP pool is now in use so I am worried about the implications.
 
I need to understand if I need to destroy / rebuild the MSDP pool?
I cannot find a great deal of information on this file.
Have I created a future problem for myself? Can I touch touch the file and reboot the media server. Or perhaps there is a command I need to execute to "fix" it?
 
Can someone help? Many thanks
Linux

    Hi pmj1 

    First up I'll say I do not know for sure the purpose of this touch file. As you have discovered all seems to be okay without it. The requirement for this touch file has been around ever since BYO media servers were allowed to have more than the single mount point. 

    It may be that as the usage of pool is probably low at present, only one mount point is being used, so the lack of the file is not a problem. I would see no problem creating the touch file and restarting NetBackup on the media server. Try running the command "/usr/openv/pdde/pdcr/bin/crcontrol --dsstat 3" and see what shows for each mount point.

    Also I think it may be required for is when using some of the MSDP utilities (e.g. msdpcheck etc.) that the existance of the file is required to ensure all mount points are checked (that's my best reading of some internal articles). 

    Really though you should contact support and ask for advice.

    Please report back if you do get an answer. 

    Thanks
    David

    In the past you were not able to add a second partition to a MSDP pool unless the file was there. You got an error. But you were able to create very large partitions and run into problems that way. Just this week I saw a client with a 90 TB partition.

    If your pool is UP and running, backups working I don't see a reason to worry. Add the file just to comply and move on.
