NetApp Plug-in For Oracle VM - python error

views-count 2119 Views

We recently updated hosts running 3.3.1 for the glibc GHOST vulnerability. A dozen other updates also went in.

It appears that python must have been updated as well.


The plugin now has python errors and cannot run:

# cat /etc/*release*
cat: /etc/lsb-release.d: Is a directory
Oracle VM server release 3.3.1
Oracle VM server release 3.3.1
Oracle VM server release 3.3.1

# python -V
Python 2.6.6

It looks like I probably need python 2.4. I have the RPM for that in my ULN mirror.

But it has so many old and broken/vulnerable dependencies that I'm afraid to go down that path and force it.

Any ideas how to fix this?

Ha ha! Fixed it. Isn't that typical, fixing it five minutes after you post?

At least partially fixed. See remaining question below.


Here was the fix -- the install of the plugin copies a few Na*.py files into /usr/lib64/python2.4/.

These are the NaElement it could not import.


  • [root@iss-vohmw2 /usr/lib64/python2.4]
  • DfmErrno.py NaServer.py OSCCache.pyo OSCPluginUtils.py PluginManager.pyc PyEnum.pyo site-packages
  • NaElement.py NaServer.pyc OSCPlugin.py OSCPluginUtils.pyc PluginManager.pyo san_linux.py
  • NaElement.pyc OSCCache.py OSCPlugin.pyc OSCPluginUtils.pyo PyEnum.py san_linux.pyc
  • NaErrno.py OSCCache.pyc OSCPlugin.pyo PluginManager.py PyEnum.pyc san_linux.pyo


I simply copied the Na*py files to the python 2.6 directory.


  • [root@iss-vohmw2 /usr/lib64/python2.6]
  • # cp ../python2.4/Na* .

But I do not know if I need any of the other files in that directory. Or are those from the older plugins that have been deprecated?
