Hi All,
I have installed 11.3.0 via appliance and it is running.
I downloaded the 11.3.1 update.
Copied the zip file to /tmp
Run zman sui zenworks_11.3.1_update.zip
Enter Username and password.
The following message appears.
"The file zenworks_11.3.1_update.zip can not be accessed by the zenworks user. Please move the file to a directory where the zenworks user has read access."

I have copied the file to /opt/novell/zenworks - same message received.
I confirmed the md5 checksum on the update file ok.
I'm entering the same username and password that I use to access the web interface.
There are no other users configured that I can see.
