[ovirt-users] iscsi data domain when engine is down

[Marcin Kruk]

OK, but what your script do, only add paths by the iscsiadm command, but
the question is if hosted-engine can see it.
I do not know how to add an extra path, for example, when I congirured
hosted-engine during installation there was only one path in the target,
but now there are four. So how can I verify how many paths are now, and how
eventually change it.
