Failed to install NetBackup Client v7.6.1 on MacOSX 10.11 El Capitan

And it would appear that the NetBackup installation script has changed the perms on the openv folder anyway:

hostname:usr root# ls -lash
total 8
...
0 drwxr-xr-x    16 root  kmem    544B Oct 20 21:18 openv

...and so in the steps above, perhaps the chown and chmod instructions should be:

4) When back in normal OSX start Terminal and enter the commands:

sudo su -
cd /usr
mkdir openv
chown root:kmem openv
chmod 755 openv
