Aloha AIXperts,
You might encountered the following error:
Could not create the NWORA resource lock file (2)
In my case, I used truss in order to find the reason which was the directory /nsr/tmp/nwora where the command should create a temporary lock file.
You can easily fix this by running:
mkdir /nsr/tmp/nwora
nsrnmoadmin -r list
If you have problems please post them in a comment.
