Hi Daniel,
Thank you for your comments!
Let me clarify some points:
About LUN:

So, the lun, which I was provided with, it was too much blank?
Hehe - I only found
writing to them once helps in general. Call it
superstitous - its the first thing I do with a new lun in case there are
some 'leftovers'. But indeed it should work without it.
About multipathd:

I'm really sorry, I failed to point that my nodes are ovirt-node-iso installations,
not generic SO installations with ovirt added to them.
Sorry, I did not use node
very much (it lacked some drivers I needed)
and - because of things like this where I need a persistant change
(multipath.conf).
I was able to manually configure the nodes - the question is: this is the expected
behavior (manual configuration)?
I'll add Fabian for this question; persistant
changes to nodes from
node.iso are his area of expertise.
Some of my nodes I just restarted and then they were able to see the LUN correctly
without any manual configuration. As oVirt provide an iso for node installation, maybe it
is important to point such behavior in the oVirt documentation.
As I said -
multipathd should be running by default. If this is the
case, pathes to the same LUN are detected at statup and mapped
correctly; no intervention necessary.
In the end you might need some special settings depending on your
storage, though.
Cheers!
