Cool. This is actually working, right?
Probably, we put this info somewhere (like under doc directory).
I've copied 'README.iscsi' to README.passthrough.
I'm about 3/4 done updating README.passthrough with this information and
will submit a patch (hopefully tomorrow)
I also plan on running some tests using NetBackup. I was hoping I was
going to get time today, but 'work' got in the way.
Hopefully in the next couple of days I can run some load testing..
Anything / any status you would like collected while running ?
